Q & A

What's in the Box

Allows you to install a bigger series gear set onto a smaller series carrier. Precision ground to ensure trueness and provide proper backlash. Fits 7.50" diameter ring gear with 1.438" diameter pinion (27 spline). Longer, LH thread ring gear bolts are included with this spacer.

Red Line 58204 Heavy Shockproof Synthetic Gear Oil, 1 Quart

Red Line Shockproof synthetic gear oil is designed for heavily loaded racing and street differentials that see heavy shock loading. It contains a unique solid dispersant that cushions gear teeth to help prevent breakage. Red Line Shockproof gear oil provides the protection of a 75W250 with the fluid thickness properties of a 75W90.

Ideal for use in sprint, midget, and dirt late model differentials as well as in rear ends using spools or lockers.

  • Fully-synthetic gear oil formula created from polyol ester base stocks offers excellent lubrication under extreme conditions
  • High viscosity-index to provide relatively constant viscosity and film thickness with varying temperature change
  • Ester base stocks and friction modifiers provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
  • Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oil
  • Exceed API GL-5 specifications
  • Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear
  • Not recommended for most synchro applications due to the product's extreme slipperiness
Richmond 92-0775-2605 Powertrax GM 7.5 10-Bolt Locking Differential

The 7.5 inch Powertrax Traction System is the latest design in traction adding differential technology. It combines the smooth operation of a limited-slip differential, with the traction performance of a locking differential. A precise synchronization mechanism eliminates the ratcheting sounds typical of other locking differentials. Special gear and spring design reduce the backlash and therefore driveline windup. An ultra-strength alloy material is used throughout, which is 67% stronger than titanium.

Installation is simple because no ring and pinion set-up is required. In addition, no special tools or oils are needed (installs in about one hour). Step by step model specific instructions are provided with every kit.
