RennTech Limited Slip Differential Mercedes-Benz SLR McLaren 03-10

RENNTECH differentials are based on OS Gikens line of Super-Lock LSD which functions as a traditional open differential in low and normal-load situations, transforming smoothly into a 100% full lock as loads rise.

The Super-Lock LSDs clutch packs make the unit incredibly quiet and smooth, without the kind of chatter usually associated with limited-slip cars - similar to the AMG units, but better in every way.
