The PEM Full Spool 8.5in 30 Spline 10 Bolt GM is a heavy-duty locking differential designed for serious off-road and high-performance driving applications where maximum traction and wheel spin elimination are essential. This full spool is built to replace the factory open differential in GM 10-bolt rear axles, providing the aggressive grip needed for rock crawling, desert racing, and extreme load hauling.
The spool forces both wheels to rotate at identical speeds under all driving conditions, eliminating differential action entirely. Its solid construction and precision spline geometry handle extreme torque loads without slippage, making it ideal for vehicles equipped with lifted suspensions, oversized tires, or high-output engines where factory differentials may fail under stress.
This product is particularly beneficial for those upgrading classic muscle cars, building dedicated off-road rigs, or maximizing traction in work trucks. The 30-spline design and 8.5-inch diameter ensure compatibility with many GM 10-bolt assemblies, making it a versatile choice for various applications.
