Ultimate Traction for GM Rear Ends

The Performance Engineering & Manufacturing Full Spool is the definitive choice for drag racers seeking maximum traction and consistent power delivery. Designed specifically for the GM 8.5-inch 10-bolt rear end, this spool eliminates differential action, ensuring that both rear wheels rotate at the exact same speed at all times. This is critical for straight-line performance and preventing one-wheel-peel scenarios.

Performance Benefits

• 30-Spline Strength: Engineered for high-torque applications and heavy-duty use.
• Full Spool Design: Provides 100% power transfer to both wheels.
• Durable Construction: Made from high-strength steel with a black powder coat finish.
• Precision Fit: Specifically machined for GM 8.5-inch 10-bolt housings.
• Weight Reduction: Optimized design to minimize rotating mass.

When you need to put all your horsepower to the pavement, a spool is the most reliable way to ensure both tires bite. Unlike limited-slip differentials that can wear out or fail under extreme load, this full spool offers a permanent, maintenance-free solution for your race car. Its robust steel construction is built to withstand the shock of high-RPM launches and aggressive gear changes. Improve your launch consistency and overall track performance with this high-quality component from GGCRACING.
