Motive Gear Differential Kit Machined Aluminum

Description

Product Overview

The Motive Gear Differential Kit is a premium replacement solution designed for front or rear differentials on GM 8.5 axle applications. Constructed from high‑strength machined aluminum, the housing provides superior rigidity while shedding excess weight compared to traditional cast iron units. The kit includes a full complement of Timken tapered bearings – carrier, front and rear pinion, and pilot where applicable – ensuring optimal load distribution and reduced wear. A precision‑cut seal, durable cover gasket, and a crush sleeve complete the package, delivering a leak‑free, low‑friction environment that maximizes power transfer to the wheels. With a compact footprint of 11 x 12 x 1.75 inches and a weight of just 5.7 pounds, the kit balances robustness with ease of handling during installation.
