Description:

The Axiom Supply CV Axle Flange Bolt is a critical fastener designed to secure your CV axle to the differential flange under extreme load and constant drivetrain stress. These bolts are torque-to-spec hardware, tightened to 58 lb-ft, and are not components you want to reuse once removed.

Factory bolts stretch, fatigue, and corrode over time—especially on trucks and UTVs that see hard use. Installing a new axle with old hardware is a gamble. That’s why Axiom Supply always recommends replacing flange bolts during any CV axle service. Fresh hardware ensures proper clamping force, torque retention, and long-term reliability.

Each bolt features a zinc-plated finish to combat corrosion and oxidation, extending service life in harsh environments like mud, snow, road salt, and off-road conditions. This is the right way to finish a CV axle install—no shortcuts.

Includes:

(8) Grade 10.9 Flange Bolts (1 Axle Side)

Things to know/Tech tips

• Torque Specification: 58 lb-ft
• Thread locker recommended during installation
• Factory bolts use 15mm heads
• Replacement bolts feature a 17mm head, which may cause clearance issues with certain lift kits

⚠️ Important:

Not compatible with CV spacer kits

If running a lift kit with tight flange clearance, factory hardware may be required
