The Strange Engineering 33-Spline Lightweight Pro-Race Spool is designed for racers who refuse to compromise on weight or strength. Engineered specifically for the GM 12-bolt 4-series carrier, this spool reduces rotating mass while providing the rock-solid reliability needed for high-horsepower applications. By locking the axles together, you ensure that every ounce of power generated by your engine is translated directly into forward motion.
When you are pushing your GM 12-bolt to its limits, the differential is often the weakest link. The D1549 Pro-Race Spool eliminates the internal spider gears that are prone to failure under heavy stress. This lightweight unit not only strengthens your drivetrain but also helps your vehicle get off the line faster by decreasing the inertia of the rotating assembly. It is the preferred choice for serious racers looking to shave seconds off their ETs while maintaining maximum durability. Upgrade your rear end with the best in the industry and feel the difference in your next launch. Find all your high-performance drivetrain needs at GGCRACING.
