King Compression Adjusters Upgrade
Add 16 levels of compression valving adjustments to your King OEM shocks with King's proprietary compression adjustable reservoirs. Easily switch from a soft, street-friendly ride to stiff, race-ready valving by simply turning the adjustment knob on the reservoirs. Includes custom valving.

Custom Colors and Finishes
While the standard King-blue components look spectacular, your custom color and finish options are only limited by your imagination. Available finishes include color anodizing, color powder coating, black zinc coating, chrome plating, and even gold plating. Contact us for pricing.

Camburg UCAs Camburg Racing Upper Control Arms
Camburg desert racing upper control arms feature welded and heat treated chromoly arms, over-sized uniball joints, and polyurethane bushings or heim joints for added strength, increased wheel travel, and improved long-travel geometry for aggressive off-road driving.

Camburg Steering Upgrade Kit
Camburg desert racing steering linkage upgrade kit is designed specifically to work with long travel suspension systems to prevent binding and bump steer while also increasing strength with oversize ball joints and rod ends. (Highly recommended.)

King OEM Performance Shock Upgrade Kits are direct bolt-on replacement shocks and/or coilovers for your vehicle and come custom tuned for the ultimate balance of on-road handling and off-road performance. They include all of the necessary hardware you need for a bolt-on installation that can easily be done over the weekend. Custom length shafts and cylinders are available to work with any brand and size lift kit. Additional options include compression adjusting reservoirs, custom colors, internal or external bypass tubes, and race-spec valving.

Servicing, Tuning, and Rebuilding
All OEM upgrade shocks and coilovers are hand-built with the same parts as all of King's other Performance Race Series shocks. They are completely serviceable, tunable, and rebuildable to last a lifetime and it only requires a few simple hand tools, a few hours, and the appropriate King replacement parts from Filthy Motorsports. If you prefer not to do the work yourself, you can always bring (or send) your shocks to us and we will service them for you.
