33-Spline L/W Pro-Race Spool - GM 12-Bolt

Strange Engineering built this lightweight 33-spline Pro-Race spool for GM 12-bolt rearends used in dedicated drag cars and serious street performance builds. It swaps out the stock diff parts and locks both wheels to the same speed for hard, repeatable launches.

The 33-spline layout mates directly to GM 12-bolt ring gear and pinion sets, offering stronger load capacity and holding up under big torque. A lighter build drops unsprung weight in the rear axle, letting the suspension react quicker during hard acceleration.

This spool is made for competition use, not daily driving. Strange Engineering holds tight manufacturing tolerances, so it fits OEM 12-bolt housings like a glove. It is a solid pick for racers focused on pure performance.
