Fitment, Shipping & Product Support
The Axiom Gold Zinc Plated Spindle Bolt (SKU AXGM1571) is a direct-fit replacement spindle bolt for the front hub assembly on 2001–2010 Chevrolet Silverado and GMC Sierra 1500, 2500HD, and 3500HD trucks (GMT800 and GMT900 platforms), also fitting select 2003–2009 Hummer H2 models. The spindle bolt retains the spindle and hub assembly — a worn, corroded, stripped, or undertorqued spindle bolt compromises front-end stability, causes premature bearing wear, and in severe cases can result in hub separation. Gold zinc-plated steel construction resists corrosion. OEM-style direct-fit replacement. Torque specification is 133 lb-ft. Lifetime warranty to the original purchaser. Replace during any hub or bearing service — do not reuse.

What Is and Is NOT Included
| Item | Included |

When to Replace the Spindle Bolt
- During any front wheel bearing replacement or hub assembly service
- When the bolt shows visible corrosion, thread damage, or deformation
- When the bolt cannot be torqued to OEM specification due to thread wear or stripping
- As a preventive replacement on high-mileage or rust-belt trucks during front-end rebuilds
- Any time the hub assembly is removed — reusing a previously torqued bolt risks thread fatigue and undertorque

Critical Compatibility
| Configuration | Notes |
|---|---|
| 2011 and newer Silverado/Sierra | Does not fit — different front hub assembly |
| Damaged or corroded spindle threads | Must be chased with a thread chaser or tap before installing the new bolt — do not force onto damaged threads |
| Worn hub bore | Will not retain the assembly correctly regardless of bolt torque — inspect before reinstalling |
| Reused spindle bolt | Risk of thread fatigue and undertorque — always replace during hub service |
Common Questions
What's the torque spec for this bolt?
133 lb-ft. Do not estimate — undertorque allows hub movement and bearing wear, while overtorque can strip threads or crack the spindle.
Does this fit my Hummer H2?
Yes, for 2003–2009 models.
Can I reuse my old spindle bolt if it looks fine?
Not recommended. Reused bolts may have lost clamping strength from thread fatigue, even if they appear undamaged. Replace during every hub or bearing service.
Does this fit a 2012 Silverado 2500HD?
No. The 2011+ Silverado/Sierra uses a different front hub assembly. This bolt is for the 2001-2010 GMT800/GMT900 platform only.
The Obsidian Take
The AXGM1571 is a small but critical fastener — the bolt that keeps the spindle and hub assembly together at the front wheel. Replace it every time the hub comes apart on a 2001-2010 GM 1500/2500HD/3500HD or compatible Hummer H2, torque it to 133 lb-ft exactly, and don't reuse the old one.
Backed by a lifetime warranty to the original purchaser — solid coverage for a part this inexpensive and this important to front-end safety.
Non-Returnable Notice: Once installed, this bolt is non-returnable. Confirm model year and torque to specification before completing the install.
