Description

High Performance Axle Assembly. The rear axles, 12 bolt, 30 spline, 31 5/16 inches long, provide critical drivetrain support to ensure optimal performance and durability. These axles transfer torque from the differential to the wheels, making them essential for vehicle operation and handling under load.

Construction and Appearance. Crafted from premium alloy steel, these axles are forged using specialized tooling and induction heat-treated to maximize torsional strength. The surface is 100% magnaflux inspected to ensure structural integrity and defect-free quality. The design includes non-tapered axles with hardened bearing seats and machined C-clip grooves to meet original equipment manufacturer (OEM) specifications.

Installation. Installation is straightforward with no drilling required, fitting directly into the designated 12-bolt Chevy rear end housing. The precise machining of the bolt pattern and snap ring grooves ensures a seamless OEM replacement.

Application. Specifically designed to fit 1966 to 1970 Biscayne and Impala models equipped with 12-bolt rear ends, these axles maintain factory compatibility and performance standards for these classic GM vehicles.
