Locked Traction for GM 10-Bolt Rear Ends

Eliminate wheel spin and ensure maximum power transfer to the pavement with the Strange Engineering 28-Spline Fullsize Spool. Designed specifically for the GM 8.5-inch 10-bolt rear end, this spool replaces your differential carrier to lock both axles together, providing 100% power delivery to both rear wheels simultaneously.

Performance Benefits

• Design: Full-size spool for maximum strength and weight reduction
• Spline Count: 28-spline compatibility for standard axle shafts
• Material: High-strength steel construction for extreme durability
• Application: Perfect for drag racing and dedicated track use

A spool is the ultimate solution for racers who need consistent, predictable launches without the risk of differential failure. By removing the spider gears and internal components of a standard differential, you reduce rotating mass and eliminate the possibility of one-wheel-peel scenarios. This unit is built to handle the torque of high-performance engines, providing a reliable connection between your ring gear and axles. If you are building a dedicated drag car or a high-performance street machine, this spool is a critical component for your rear-end build. Find all your essential drivetrain upgrades at GGCRACING.
