It measures 68.375 in. compressed length, has a 69.375 in. drive shaft length, and uses bolt-on ends for straightforward replacement of the original rear shaft assembly. The design includes a 1 in. max slip, 0.083 in. wall thickness, and no slip yoke, making it a direct-fit solution for the specified rear 8.8 in. axle configuration.

Common Problems This Part Can Address
- Vibration from a worn or out-of-balance rear driveshaft

Installation Notes and Tips
Verify rear axle configuration and shaft length before installation. This assembly uses bolt-on ends and is phased at 90 degrees, so alignment during installation matters for driveline smoothness.
