King coil springs are manufactured to our specifications in the USA using the finest quality, high tensile, chrome silicon wire available. Specifically wound for off-road applications, spring rates, wire diameters and coil lengths have been developed through extensive real world testing on all types of terrain.
Machined billet nylon coil sliders maintain proper spring alignment and silent operation while withstanding temperatures up to 450 degrees.
Progressive dual rate spring applications use lockable secondary nuts threaded onto the body to allow precise adjustment of secondary spring engagement.
Large 7/8” or 1” diameter shafts have a tensile strength of 100,000 pounds per square inch. They are induction hardened to 55-60 on the Rockwell scale to combat rock bruising and micro-polished to a 6 RA finish for extended seal life.
Our rod end attachment method has been in use for 14 years without a single failure. A heat treated stainless bung is pressed on then tig welded to the end of the shaft. The 7075 cold drawn aluminium rod end is then threaded onto the bung. This design is free of any stress risers created when threading the shaft and gives incredible strength.
Shocks cylinders are precision bored within x/- .001 then honed after zinc plating to remove buildup for a tight piston seal and optimum valving function.
Heat treated stainless alloy valve shims do not fracture like plain carbon steel and resist deformation at high temperatures providing consistent fade free performance.
Long lasting, Teflon impregnated bronze, wear band has overlapping ends for enhanced sealing and is preloaded with an additional Viton o-ring to create a tight seal with the precision bored and honed shock
Viton rod seals withstand temps up to 450 degrees. Wiper seals are machined with diamond tooling from a high temperature resistant carbon composite material.
Replaceable Teflon lined stainless steel spherical bearings will not rust and provide smooth articulation with no metal to metal contact.
Lightweight hard Anodised 6063 aluminium alloy reservoirs dissipate heat quickly and will not rust due to gas charging contamination. Several colours are available to match your vehicle.
Threaded end caps withstand high pressures and ease in maintenance. Several colours are available to match your vehicle.
Billet aluminium end cap with double sealed Schrader cover that mounts to the cap, not the valve itself creates a positive seal and keeps dirt and moisture out.
High quality fittings are mated to Aeroquip high pressure hoses which resist abrasion and allow a tighter bend radius without kinking like braided stainless or cloth lines do.
