KSP PERFORMANCE Caster/Camber Bolt Kit for Chevy GMC Trucks — Aluminum ±1.5° Adjustable, Includes Bolts & Cams

Restore proper suspension geometry and reduce uneven tire wear without replacing the entire control arm. This KSP kit includes precision-machined cams, bolts and locking nuts designed to work where factory hardware offers no adjustment. Built from lightweight aluminum alloy, the components resist cracking while giving you the fine movement needed to bring a non-adjustable suspension back toward factory specifications.

How will this kit affect steering and tire wear?

Small caster and camber errors can cause pull, wandering, and premature shoulder wear on tires. Installing KSP's adjustable bolts lets you dial in vertical angle settings to improve directional stability and even out contact patches across the tread.

• Corrects camber and caster differences up to ±1.5° per side
• Reduces uneven tire wear and extends tire life
• Helps stabilize steering feel and return-to-center behavior

What exactly comes in the box and how many vehicles does one kit service?

Each set ships with the hardware required for one side of the vehicle: two bolts, two lug-style nuts and four cam washers. For a full-axle installation you must order two sets; the kit is intended to replace worn or broken upper control arm bolts and add adjustability where none existed before.

• Included: 2 bolts, 2 nuts, 4 cams (one-side coverage)
• Order quantity: 2 sets for both sides of a vehicle
• No grease required on bolts and cams during installation

How durable and precise are the KSP alignment parts?

Manufactured from high-quality aluminum alloy, the cams and bolts resist cracking and deliver consistent incremental adjustments. The machined cam profile provides repeatable angle changes so you can achieve precise alignment readings at the shop or at home.

• Aluminum construction balances strength and weight
• Engineered cam geometry for predictable angle changes
• Works with stock control arms on many Chevy, GMC, Hummer and GM-based vans/trucks

Who is this for? This kit is aimed at DIY mechanics, alignment shops and owners of Silverado, Sierra, Yukon, Express, Savana, Hummer H2/H3 and compatible GM trucks who need to restore or fine-tune caster and camber without swapping control arms. If your vehicle shows uneven tire wear, steering pull, or if you’re upgrading suspension components and want adjustable alignment points, this KSP bolt and cam kit offers an affordable, bolt-on solution.
