1955-1967 Austin Healey 100-6, and Big Healey 3000

This Phantom Grip LSD Conversion is designed for the classic Austin Healey 100-6 and Roadster Big-Healey 3000 differentials.

Phantom Grip Limited Slip Conversion Kit installs into your non-LSD open differential, converting it into a proven, competitive limited-slip differential that enhances traction. Phantom Grip’s 1.5-way LSD will considerably improve handling in daily-driven street-strip warriors or full-race vehicles. All Phantom Grip products are constructed from only the highest-quality, hand-selected materials. With three decades of rigorous professional performance testing (street, drag racing, rally racing, hill climb, driving on dirt trails, skid pad testing, and testing in rain and snow, drift, and more), we have fine-tuned each application through specific heat-treating and Rockwell testing to achieve maximum performance and reliability. Each Phantom Grip LSD Kit is assembled with pressure-tested matched sets of progressive-rate springs to achieve equal load distribution to the LSD disc plates, which dramatically enhances reliability and performance.
