King OEM Performance kits are custom tuned to provide your 2019+ Chevy and GMC 1500, Trail Boss and AT4 Coil-Over Kit with unparalleled levels of performance and ride quality.

 

Each kit has been subjected to punishing real world testing to develop the optimal damping curve and spring rate for your vehicle. Easy bolt-on installation for stock height or with custom kits for trucks running lifted aftermarket suspensions.

​

BODY

2.5” Shock cylinders are precision bored to within +/- .001, then honed after cadmium plating to remove buildup for a tight piston seal and optimum valving function.

 

VALVING

Wear bands are made from a Rulon composite that offers incredible wear resistance, low deformation under load and high compressive strength. Overlapping end design enhances sealing.

​

SHAFT

Large 3/4” or 7/8” diameter shafts have a minimum tensile strength of 100,000 pounds per square inch. They are hard chromed and micro-polished to a 6 RA finish for extended seal life.

​

MOUNTING

High strength rod end designed for proper clearance on your application. Steel Teflon lined spherical bearings for smooth articulation and long life with no metal to metal contact.

​

PISTON

Internally threaded top cap design threads over the shock body to enable maximum piston travel inside the shock body.

The heat treated 6061 aluminium alloy piston has our highly developed port configurations that contribute to the unique damping performance and famous King ride quality.

 

RESERVOIR

Lightweight hard Anodised 6063 aluminium alloy reservoirs dissipate heat quickly and will not rust due to gas charging contamination.

High quality fittings are mated to Aeroquip high pressure hoses which resist abrasion and kinking.
