One of the racers who have been caught up in the KOH whirlwind is Australian Ben Napier. Ben had been driving 4x4’s since he took his driver’s license test behind the wheel of the family’s 1972 Land Rover. Ben then stepped it up when a friend asked him to compete in the Australian W.E. Rock series, which he did, and they had great success. Ben was having fun in the WE Rock series but he had read stories and seen videos of the newly developed King of the Hammers race that really sparked his interest.

How to pick the proper shocks for your vehicle

Basic information needed when ordering shocks

General mounting information and guidelines

How shocks create heat

INTRO:

King Shocks has a comprehensive product line with shocks available for any application from stock trucks to all out race vehicles. Selecting the shock you need depends on your driving style, your vehicles specific configuration and its intended use. A shock that works well on a lightweight sand car or UTV cannot deliver the same results on a heavy 4X4 truck or unlimited race vehicle.

Stock vehicles are sometimes limited when it comes to shock upgrades due to clearance issues that may exist. If you have a stock or lifted truck, the easiest way to get a huge performance advantage is to install one of our bolt on OEM upgrade kits that are designed to work with your vehicle. The OEM upgrade kits have already been subjected to hours of real world testing to develop the correct damping curves and/or spring rates to match your vehicle. The same is true if you need shocks for your UTV, King has shock upgrade kits for stock or long travel UTV's that deliver incredible performance.

King Shocks makes many different shocks that are designed to work with your suspension. In order to select the correct shock you need to determine what each shock type does.

COILOVER SHOCKS:

A coilover shock incorporates a coil spring mounted around the outside of the shock body that holds the vehicles weight. A single coilover on each wheel will hold the vehicle up and provide damping. You can also run a coilover shock as a coil carrier when used with a bypass shock. When used as a coil carrier the coilover has no valving inside it only suspends the cars weight while the bypass shock does the damping. A third coilover configuration combines two shocks in one. It includes a coil spring on the lower portion of the shock body to support the vehicle weight with a bypass shock on the top portion of the shock body to control the damping. The Coilpass shock was developed for racing classes that are limited to one shock per wheel. Cars that run a Coilpass are usually designed to accommodate the additional length of the Coilpass shock.

BYPASS SHOCKS:

Bypass shocks provide externally adjustable damping. Bypass tubes are welded to the outside of the shock body that allow the shock fluid to flow around the piston. Each tube has a bypass valve that controls how much fluid can pass. When the valve is opened up, it allows fluid to pass easily (soft). When the valve is closed down, less fluid is able to pass (firm). The tubes are arranged on the outside of the shock according to the intended application. They are position sensitive, which means they are able to individually control the amount of damping in several stages as the piston cycles up and down. The bypass valves allow you to achieve non-linear damping curves which means you can have the shock soft at ride height for a smooth ride and progressively firmer as the shock compresses for the bigger bumps. Bypass shocks are used with an existing means of supporting the vehicle like leaf springs or a coilover. Bypass shocks are necessary if you are subjecting your vehicle to high speeds over rough terrain

SMOOTH BODY SHOCKS:

King Smoothie shocks are a major upgrade from your OEM shocks. They contain the same race-proven damping technology and superior construction that King's all-out race shocks have. Smoothie shocks are used with an existing means of supporting the vehicle like leaf springs, torsion bars or coils. They have adjustable valving and are serviceable with simple hand tools. Several reservoir styles are available. Smoothie shocks with external reservoirs can be fitted with the Wide Range Compression Adjuster that allows you to change the compression valving from very soft to very firm with the twist of a knob. The Wide Range Compression adjuster is the perfect addition for vehicles that tow or occasionally carry heavy loads or additional passengers. King Smoothie shocks are custom built in several lengths and mounting options to fit your vehicle.

AIR SHOCKS:

King air shocks provide a compact and lightweight option when used in the appropriate application. Air shocks ride on the pressurized gas charge inside (nitrogen). All air shocks are limited in their use by the physical properties of nitrogen gas. Nitrogen expands when it gets hot and contracts when it cools. In a lightweight rock crawler that only travels a few hundred yards during a full day of competition this is not a problem. If you plan on running on the trail or the street for any length of time it becomes an issue. When shocks work, they create heat. The heat causes the gas inside an air shock to expand which then extends the shock and changes the damping, it gets stiff. The same thing happens in reverse when the gas inside cools. If you are driving a competition only rig and are looking to save weight above all else, air shocks may be the right shock for you.

IN THE END:

Regardless of your application, King Shock's technicians have a solution to your damping needs. King Shocks will work with you to achieve the best handling and performance possible from your suspension. If a custom project is needed, King is the industry leader in advanced design, manufacturing and engineering. When it comes to your special engineering projects, King Shocks has the necessary depth of knowledge to deliver everything from conceptual design consultation to working prototypes, production parts or one off custom creations. Whether you are restoring a vintage racer, building a monster truck, or in the conceptual stage of a brand new chassis, we have the knowhow and the tools necessary to help you accomplish your goals.

BASIC INFORMATION NEEDED WHEN ORDERING SHOCKS

If you are building your own chassis or upgrading to King Shocks on your existing vehicle you will need to know some technical information before you place your shock order. The suspension will need to be cycled from full extension to full compression so usable suspension travel (including articulation on straight axle applications) can be measured. You will need to determine the desired ride height, which is measured from the lowest point on the chassis to level ground. You need to determine the location of the ride height in relation to the suspension travel. It's common to set the ride height at mid-travel but you can increase droop by sitting lower than the mid-point or conversely increase up-travel by sitting above the mid-point of travel. The weight of the vehicle will be needed to help determine spring rate. If you have access to wheel scales you can check each wheel separately. Is the vehicle front engine, mid engine or rear engine? What is the front to rear weight ratio? What size tires are you using? What are your track width and wheelbase dimensions? What speeds will you be running? What type of terrain will you encounter? The more detail you can provide the easier it will be to design your shocks.

GENERAL MOUNTING INFORMATION AND GUIDELINES

King Shocks is dedicated to leading the way in design and technology through continuous testing and product development work with top teams worldwide. One of the characteristics that sets off-road apart from other forms of racing is the lack of "belly-button" cars that are identical with the exception of a headlight decal or fiberglass body panels. Regardless if you are Rock Racing, Crawling, or racing Short Course, Rally or Desert Off-road, most chassis designs are totally unique to the builder and change frequently as new technology is continuously evolving. There is one constant that never changes, King Shocks can and will, build whatever shock is necessary to provide the maximum suspension performance for your vehicle. King Shocks got their start building custom shocks over a decade ago and they continue to excel at it to this day.

King offers a multitude of custom options and features to choose from for each shock type they produce. The type of shock (or shocks) you need will be determined by several factors including their intended use, the weight of the vehicle, how the vehicle is suspended, in example leaf springs, torsion bars or coilover shocks, the speeds you will reach and the terrain you operate in. A Rock Crawler may travel only a mile or two at low speeds during an entire competition or trail run. A simple, light weight, airshock might be the perfect choice. Conversely, an 8000 Lb. Trophy Truck with over 30 inches of rear wheel travel reaching speeds in excess of 100 mph for hours on end needs extensive damping control, bypass adjustability and components able to withstand the elevated temperatures, incredible shaft speeds and dynamic loads generated.

Suspension design is difficult enough when the travel limits are 2-3 inches, when you are traveling 2-3 feet the variables grow exponentially. King Shocks won't go so far as to tell you how your chassis or suspension should be designed but there are a few general principles that will help to make your shock packaging more functional. Shock shafts extend and compress in a linear path while most suspension components travel in an arc. As a general rule, the shock should be mounted so the shaft is as close to 90 degrees, as practical, to the moving suspension member at full compression. During normal operation your King shocks can reach high temperatures. They should be located away from potential spills of flammable liquids like fuel, oil or transmission fluid. Shocks should be exposed to direct airflow when possible to aid cooling and isolated from external heat sources like coolers, turbochargers or exhaust pipes. Excessive heat exposure may damage the seals. Shocks and reservoirs should be securely mounted taking care to provide ample clearance between the shocks and the suspension and/or chassis throughout the entire range of motion to prevent damage to the shocks from contact, or excessive side loading or binding. When clamping remote reservoirs locate the hose clamps at either end of the reservoir to allow expansion and prevent crushing the cylinder. Make sure hoses will not rub against the chassis or body panels or come in contact with sharp objects that may cut into the hose. Care needs to be taken when welding or grinding. Grinding sparks and weld splatter can damage shafts, hoses and shock bodies. When welding around your shocks, make sure the ground strap is directly adjacent to the area being welded. If the welding current is allowed to travel through the shock shaft and arc to nearby metals, permanent damage will be made to the hard chrome plating on the shafts.

HOW SHOCKS CREATE HEAT

Many are familiar with the outside of a shock but don't know what happens inside. Shocks are comprised of a body that is in the form of a tube that attaches to the chassis of the vehicle in most cases. The other end of the shock is a shaft that mounts to the moving parts of your suspension. The shaft moves in and out of the shock body as the suspension goes up and down. The shock body is filled with specially formulated fluid. The fluid has a high viscosity. Viscosity is the property of resistance to flow. Water has a low viscosity, honey has a high viscosity. A piston is attached to the end of the shaft. As the shaft cycles in and out, the piston is pushed and pulled through the fluid. The piston has a wear band on the outside diameter that allows the piston to slide inside the bore and seals against the shock body forcing the fluid to go through openings in the piston known as ports. The ports allow a path for the fluid to pass through the piston but for the most part, they don't control the amount of fluid that is allowed to flow. Thin plates called shims are stacked on top and bottom of the piston covering the ports. The shims are made in different diameters and thicknesses. As the piston moves through the fluid, the shims flex, opening the ports and allowing the fluid to pass through. The ports open and close depending on the velocity or speed of the piston moving through the shock fluid. Thicker shims flex less allowing less fluid to pass making the shock firmer. Thinner shims will create less resistance making the shock softer. By restricting the high viscosity shock fluid as it moves through the ports, the fluid is subject to friction that in turn creates heat. The heat dissipates the energy produced as the suspension cycles. There are thousands of shim configurations possible to precisely tune the shock to match your vehicle and driving style. The right shocks will enhance all aspects of your driving experience including traction, braking and steering. If you are building a new vehicle or upgrading an existing one, King Shocks has what you need to get the most performance possible out of your suspension.
