Axiom Supply Zinc Plated Spindle Bolt — GM Truck (Silverado/Sierra, plus Avalanche, Suburban, Yukon, and Hummer H2) SKU: AXGM1571

Overview

This is a premium gold zinc plated spindle bolt from Axiom Supply, engineered to securely fasten the wheel bearing to the spindle on a wide range of GM trucks and SUVs. It torques to 133 lb·ft to create the clamping force needed to keep the hub assembly tight under load, and Axiom recommends replacing these bolts every time the wheel bearing is serviced.

Before ordering: This bolt is sold individually. "8-lug" and "6-lug" identify the truck class by its wheel pattern — they are not the spindle bolt count. Spindle bolt quantity is a separate spec tied to the wheel bearing hub flange: 8-lug-class trucks need 4 spindle bolts per side; 6-lug-class trucks need 3 spindle bolts per side. Verified fitment spans a wide range of Chevrolet, GMC, and Hummer models and years — some well beyond the 2001–2010 range referenced in the product name, including Silverado/Sierra 1500 through 2018 and Suburban/Yukon through 2020. Confirm your exact make, model, and year against the Verified Fitment table before ordering.

Required separately: This is a bolt only. The wheel bearing itself, and any other hardware needed for a complete bearing service, are not included.

What Is and Is NOT Included

Not included:

• Wheel bearing itself
• Other wheel bearing service hardware

Critical Compatibility

• Quantity by lug pattern: Sold individually. 8-lug GM trucks require 4 bolts per side; 6-lug GM trucks require 3 bolts per side. Confirm your truck's lug count and order the correct total quantity.
• Torque specification: Torque to 133 lb·ft. This is a high-torque application.
• Single-use recommendation: Because of the high torque applied and real-world exposure to rust, moisture, and road debris, Axiom strongly advises replacing these bolts every time the wheel bearing is serviced or replaced. Once a bolt has been torque-cycled and exposed to corrosion, it cannot guarantee the same clamping strength a second time.
• Multi-make coverage: Verified across Chevrolet, GMC, and Hummer H2 applications built on shared GM platforms. Confirm your specific make/model/year against the table rather than assuming cross-make interchangeability beyond what's listed.
• Broader range than the product name suggests: While the product name references 2001–2010, verified fitment for several models (Silverado/Sierra 1500, Suburban, Yukon) extends earlier and later than that range. Confirm your specific model and year against the table above rather than the product name alone.

Installation Notes

Torque to 133 lb·ft. Install a new bolt with every wheel bearing replacement — do not reuse spindle bolts from a previous service. No further step-by-step manufacturer installation instructions were supplied for this task; follow current manufacturer procedures for your specific wheel bearing service, including proper torque sequence, before returning the vehicle to service.

The Obsidian Take

The AXGM1571 is a gold zinc plated spindle bolt that secures the wheel bearing to the spindle across a broad range of GM trucks and SUVs, torqued to 133 lb·ft. Axiom's position is that these bolts should be treated as single-use, torqued once and replaced at every subsequent bearing service, since a bolt that has already been torque-cycled and exposed to the elements can't be relied on to deliver the same clamping force again. The two things to confirm before ordering are your exact model/year against the fitment table and your correct quantity based on lug pattern — 4 per side for 8-lug trucks, 3 per side for 6-lug trucks.

This Product Is For You If

• You own a Chevrolet, GMC, or Hummer H2 model whose exact make, model, and year appears in the Verified Fitment table.
• You are servicing or replacing a front wheel bearing and need new spindle bolts as part of that job.
• You know your truck's lug pattern (6-lug or 8-lug) and are ordering the correct quantity.

This Product Is Not For You If

• Your vehicle's make, model, or year is not confirmed in the Verified Fitment table.
• You are unsure of your lug pattern and have not confirmed the correct bolt quantity.
• You are looking to reuse existing spindle bolts rather than replace them — Axiom does not recommend this.
• You are looking for the wheel bearing itself or other service hardware — none of that is included with this listing.

Common Questions

How many bolts do I need?
8-lug GM trucks need 4 bolts per side. 6-lug GM trucks need 3 bolts per side. This listing is for a single bolt — order the total quantity your truck requires.

Do I need to replace these every time I service the wheel bearing?
Yes — Axiom strongly recommends new spindle bolts with every wheel bearing service, since a bolt that has already been torqued and exposed to corrosion can't guarantee the same clamping strength a second time.

What torque spec do these bolts use?
133 lb·ft.

What is the warranty on this part?
Axiom Supply covers this part for life against manufacturer defects, premature wear, and breakage, under the Axiom No-Nonsense Lifetime Warranty. Coverage applies to the original purchaser when purchased directly from Axiom Supply or an authorized dealer. See full warranty summary below.

Does off-road use, towing, or a lifted suspension void the warranty?
No. Axiom's warranty has no restrictions for normal vehicle use, modifications, off-road use, towing, hauling, oversized tires, or lifted suspension systems.
