XDDPRO Upper Control Arm Cam Bolt Kit for 1999–2018 Chevy/GMC (4 PCS) ±1.5° Alloy Steel Alignment Hardware

XDDPRO upper control arm alignment cam bolt kit provides a simple, durable way to restore and fine-tune camber, caster and toe on many 1999–2018 Chevy, GMC and Hummer trucks.

This kit includes precision-machined cam bolts, lug hardware and replacement eccentrics designed to fit upper control arms on a wide range of 6‑ and 8‑lug trucks. Built from heat-treated alloy steel, the parts resist deformation and are sized to deliver up to ±1.5° of alignment correction where factory slots are not adjustable. The set replaces worn factory pieces, helping you regain predictable steering and even tire wear without major suspension changes.

How will this cam bolt kit improve my truck’s steering and tire wear?

When the factory upper control arm pivot hardware becomes worn or was never adjustable, wheel angles can drift, causing uneven tire wear and loose steering feel. Installing adjustable cam bolts lets you dial in camber and caster and make fine toe corrections to match manufacturer specs or compensate for slight body sag.

• Provides up to ±1.5° camber/caster adjustment for better tire contact.
• Restores alignment range on non-adjustable factory pivots.
• Reduces uneven wear and improves straight-line tracking.

Which models and years will these bolts fit?

The XDDPRO kit is engineered for many Chevrolet and GMC 1500/2500/3500 platforms across model years and select Hummer H2 applications. Confirm fitment against your truck’s lug count and control arm layout before ordering to ensure compatibility.

• Fits 1999–2018 Chevy Silverado 1500 (6-lug) and GMC Sierra 1500 (6-lug).
• Compatible with 2001–2010 Silverado/Sierra 1500HD, 2500, 2500HD, 3500 (2WD & 4WD).
• Includes coverage for Suburban/Avalanche/Yukon XL 2500 and Hummer H2/H2T where specified.

What’s included and how durable are the parts?

The package delivers complete upper control arm alignment hardware so you have everything needed to replace worn eccentric bolts. Components are machined from alloy steel and treated to resist bending, preserving alignment settings under normal driving conditions.

• Total hardware: 16 pieces — 8 cams, 4 lug nuts, 4 lug bolts for a full upper-arm fitment.
• Heat-treated alloy construction for strength and long life.
• Designed as a direct replacement for factory slotted eccentrics.

How difficult is installation and what should I know before starting?

Installation is intended to be straightforward for anyone comfortable working on suspension pivots. These bolts replace original upper control arm hardware; minimal tools are required and no grease should be applied to the cams. If your truck uses a lift that repositions upper control arms, this kit will not correct the resulting geometry.

• Straight swap-in for worn or damaged upper-control-arm bolts.
• Do not grease cams — install dry to maintain proper friction and positioning.
• Not compatible with lift kits that relocate upper control arms.

Who is this for: The XDDPRO cam bolt kit suits owners of compatible Chevy, GMC and Hummer trucks who want an affordable, OEM-style way to restore alignment range and improve handling without replacing major suspension components. It’s ideal for technicians, DIY mechanics and fleet service shops needing a robust solution to correct camber and caster on older or high-mileage vehicles.
