KSP PERFORMANCE Caster/Camber Bolt Kit for Chevy GMC Silverado Sierra — Aluminium ±1.5° Adjustment, Includes Bolts & Cams

KSP PERFORMANCE caster/camber bolt kit lets you fine-tune suspension alignment up to ±1.5° to restore factory angles and reduce uneven tire wear on compatible Chevy, GMC, Yukon, Savana and Hummer models.

If your vehicle’s upper control arm hardware is worn, damaged or non-adjustable from the factory, this KSP alignment kit provides replaceable bolts, cams and nuts that enable incremental caster and camber correction. Built from high-grade aluminum, the components resist cracking and allow precise alignment without modifying control arms. The kit contains the parts needed for one side of the vehicle so you can repair or upgrade a single mounting point or order two sets for a full-axle adjustment.

How does this kit restore proper alignment on older or non-adjustable control arms?

The eccentric cams and replacement bolts are shaped to shift the vertical pivot point, giving technicians and DIYers the ability to change camber and caster within a limited but useful range. Installing these parts re-centers wheel position relative to the road, improving steering response and contact patch consistency.

• Includes 2 bolts, 2 lug-style nuts and 4 eccentric cams for one side
• Provides up to ±1.5° of vertical angle adjustment
• Useful on worn or factory non-adjustable upper control arms
• Aluminum construction reduces risk of cracking compared with cheaper alloys

Will this fit my truck or SUV and what models are supported?

The kit is designed to work with many Chevrolet and GMC platforms and selected full-size vans and Hummers where the upper control arm uses similar mounting geometry. It’s compatible with popular trucks and SUVs such as Silverado, Sierra 1500/2500, Yukon, Express/Savana 1500/2500 and Hummer H2/H3, but confirm fit by comparing your vehicle’s control arm bolt size and mounting style.

• Common fit for Chevy Silverado and GMC Sierra 1500/2500 models
• Fits Yukon and full-size vans like Express and Savana 1500/2500
• Compatible with Hummer H2 and H3 suspension mounts using similar bolts
• Recommended to verify part dimensions before purchase for uncommon model years

How difficult is installation and what tools are required?

Installation is straightforward for anyone familiar with basic suspension work: remove the original upper control arm bolts, swap in the new eccentric cams and bolts, then torque to specification and have the alignment checked. No grease is required on the bolts or cams; a professional alignment after installation is advised to lock in proper settings.

• Basic hand tools and a torque wrench are typically sufficient
• Installation replaces the original upper control arm bolt hardware
• One-sided kit — purchase two sets for both driver and passenger sides
• Final professional wheel alignment recommended after install

What does the package include and are there maintenance tips?

The kit ships with everything needed for one side: two bolts, two nuts and four cams to give you precise angular control at the mounting point. These aluminum parts are designed for durability, and they do not require grease; periodic visual inspection is enough unless you experience unusual movement or wear.

• Package: 2 bolts, 2 lug nuts and 4 eccentric cams
• Intended to replace worn or broken upper control arm hardware
• No lubrication required; inspect periodically for tightness and wear
• Buy two kits if you plan to adjust both sides of the vehicle

Who is this for: This KSP PERFORMANCE caster/camber bolt kit is aimed at owners and mechanics working on full-size Chevy and GMC trucks, SUVs, vans and compatible Hummers who need a reliable, non-invasive way to regain alignment control. It’s ideal for vehicles showing uneven tire wear, steering pull, or for anyone updating worn suspension bolts without replacing control arms. Professional installers, experienced DIYers and fleet technicians will appreciate the material quality and the ability to dial in alignment without major suspension modification.
