Motive Gear Differential Bearing Kit Alloy Steel

Description

Product Overview

The Motive Gear Differential Bearing Kit is a comprehensive solution designed for Dana 35 front or rear differentials. Constructed from high‑grade alloy steel, each component offers exceptional strength and wear resistance. The kit includes a set of Koyo tapered roller bearings (carrier, front and rear pinion, and pilot where applicable), a full complement of 3/8″ ring‑gear bolts, a brush, cover gasket (or RTV), crush sleeve (or preload shim), and a premium seal. All parts are machined to precise tolerances, ensuring a perfect fit with the OEM specifications (part number R35JRMK). At 5.29 lb and measuring 11 × 12 × 2 in, the kit balances robust construction with manageable weight for easy installation.

Usage

Designed for both daily drivers and performance enthusiasts, this kit excels in demanding environments. Whether you are rebuilding a street‑legal truck, preparing a race‑ready off‑road vehicle, or maintaining a fleet vehicle, the kit reduces friction and eliminates play in the differential, resulting in smoother power delivery and improved handling. Ideal for applications that experience high shock loads, such as rally, drag, or off‑road racing, the kit’s roller bearings and reinforced seals maintain stability under extreme torque and temperature variations.
