Fitment, Shipping & Product Support
This cam pin set will NOT work with the factory plastic cam guides installed. The plastic guides must be removed before this pin set will install and function correctly.
The Axiom Alignment Cam Pin Set (SKU AXGM86325) is a direct-fit replacement cam pin set for the upper control arm alignment slots on 1999–2026 Chevrolet Silverado and GMC Sierra 1500, 2500HD, and 3500HD trucks. Cam pins lock the upper control arm in the correct caster and camber position, preventing alignment drift under heavy load, towing, and rough terrain. Worn, corroded, or missing cam pins allow the upper control arm to shift position, causing caster and camber to drift out of spec — resulting in steering wander, uneven tire wear, and inconsistent handling. Includes 8 gold zinc-plated cam pins total — enough for both sides. Heavy-duty metal construction resists corrosion. Will not work with factory plastic cam guides — these must be removed before installation. Front-end alignment is required after installation. Lifetime warranty to the original purchaser.

| Worn or elongated UCA slots | Will not retain the new cam pins correctly — inspect before installing |
| Mismatched pin condition left/right | Causes unequal caster/camber settings — replace both sides simultaneously |
Common Questions
Will this work with my factory cam guides still installed?
No. The factory plastic cam guides must be removed before this pin set will install and function correctly. This is a mandatory step, not optional.
How many pins are in the set?
8 total — enough to service both sides of the vehicle.
Do I need an alignment after installing this?
Yes. A full front-end alignment (caster, camber, toe) is required after cam pin replacement. Do not drive until aligned by a qualified technician.
Should I replace my cam bolts at the same time?
If your cam bolts are also worn or seized, yes — Axiom's AXGM0026 cam bolt kit pairs with this set so both critical alignment hardware pieces get replaced in one alignment appointment.
The Obsidian Take
The AXGM86325 is for the 1999-2026 Silverado/Sierra 1500/2500HD/3500HD owner whose alignment won't hold — bent, crushed, or corroded cam pins are a common, overlooked cause of caster and camber drift. 8 gold zinc-plated pins, lifetime warranty, broad platform coverage across four chassis generations.
The one step that can't be skipped: remove the factory plastic cam guides first. This kit physically will not install or function with them in place.
Non-Returnable Notice: Once installed, this kit is non-returnable. A full front-end alignment is required after installation — do not drive until completed.
