Info

These competition 305-106 quick-change rear ends from Winters Performance are designed for 305 Sprint cars! Built with a 42 Spline Ultralight Long Spline Axle, this assembly utilizes a REM® Finish 8” 4.11 Ring Gear that is 20% smaller and 20% lighter. From a performance standpoint, smaller cubic inch engines will benefit the most. This Direct Replacement Rear uses the same length Drive Shaft, Torque Tube and Inboard Brake Kit. Accepts 1-3/8” 10 Spline Quick Change Gears.

Thermal Dispersant Coating

While being 1/3 lighter than aluminum, magnesium acts as an insulator and holds in heat resulting in higher temperatures inside your rear. This very effective corrosion resistant coating helps cool your rear assembly by dispersing the heat, therefore resulting in cooler operating temperatures!
