Bolt Kit for Alum Pinion Mounts

The Bolt Kit for Alum Pinion Mounts by Wehrs Machine is engineered for builders and mechanics who demand precision in their rear-end geometry and suspension setup. Whether you're upgrading a street rod, drag car, or high-performance street machine, this fastener kit secures aluminum pinion mounts with the exacting tolerances that dedicated chassis work requires. Pinion mount bolts are critical load-bearing fasteners that directly influence axle alignment, driveshaft runout, and overall suspension geometry—making quality hardware non-negotiable for any serious modification project.

Wehrs Machine has built its reputation on manufacturing hard-anodized aluminum components and matching fastener kits that work seamlessly with their mounts. This bolt kit is designed to mate securely with Wehrs aluminum pinion mount systems, using grade-appropriate hardware that resists vibration loosening and corrosion under the demanding conditions of a working drivetrain. The kit's compact footprint—measuring 5 x 1.4 x 7.95 inches and weighing just 1.53 lbs—reflects efficient packaging of all necessary fasteners, washers, and locating hardware required for proper assembly. Proper fastener selection ensures consistent clamping force across aluminum surfaces without galling or thread damage.

This kit is ideal for anyone installing or refreshing a Wehrs Machine aluminum pinion mount on independent rear suspension builds, vintage hot rods, or competition vehicles where repeatability and alignment accuracy matter. Mechanics and enthusiasts will appreciate receiving a complete, engineered solution rather than sourcing mismatched fasteners that could compromise mount integrity. Installation requires following Wehrs specification torque values and sequence procedures to ensure even load distribution and prevent frame-mount distortion. Verify your specific pinion mount model (WM205 or compatible) before ordering to guarantee proper fit and fastener compatibility.
