Mini Spool 7.5 GM 10Bolt 26spl

The Mini Spool 7.5 GM 10Bolt 26spl by Allstar Performance is a compact limited-slip differential upgrade engineered for street and strip vehicles running a GM 10-bolt rear axle. This spool eliminates wheel hop and improves traction on acceleration by locking both wheels together during hard cornering and launch, making it an essential upgrade for anyone serious about consistent off-the-line performance and handling predictability in daily driving or bracket racing scenarios.

Constructed with precision engineering, the Mini Spool 7.5 features a 26-spline configuration that locks into your existing 10-bolt carrier without requiring complex disassembly or differential case modifications. The compact design weighs just 3.75 pounds, keeping rotating mass minimal while maximizing rigidity and power delivery efficiency. By converting your open differential into a true spool arrangement, you gain the advantage of equal power distribution to both rear wheels, dramatically reducing tire slip and improving launch authority while maintaining street-legal operation on public roads when driven responsibly.

This upgrade is ideal for Chevrolet, Pontiac, and Oldsmobile vehicles equipped with 7.5-inch GM 10-bolt axles—particularly third-generation F-bodies, G-bodies, and A-bodies that see frequent autocross, drag strip, or spirited street use. Installation requires basic rear-axle familiarity and standard shop tools; no exotic fabrication needed. Whether you're optimizing a resto-mod, building a weekend track car, or upgrading a street performance vehicle, the Mini Spool 7.5 GM 10Bolt 26spl delivers straightforward, affordable traction without the complexity or cost of a full locker conversion.
