With RacingDiffs Progressive LSD Conversion set, you will no longer suffer from losing grip!
The set is mounted on your standard differential, transforming it into a clutch-type 25% lock Limited Slip Differential.


There are 2 key points which differ RacingDiffs kit from any other on the market:

1. NO material warping. RacingDiffs engineers decided to make NO compromise on the material quality and made the plates from the highest quality tool steel, heat treated and nitrated to achieve the highest wear resistance and added Friction discs between plates and spider gears that are made from the same material as RacingDiffs LSD clutch plates. This solution successfully stopped metal shavings, which is the biggest problem of cheap LSD kits.

2. Maximum performance increase. The main goal of the kit is to achieve the progressiveness. RacingDiffs applied the design from ZF plated LSD units with Ramp Angles. The specific Ramp angle design allows for low pre-load, while still retaining a progressive lock capability; essentially, although the vehicle will feel like driving with an open diff in slow turns/street driving, it will transmit torque to both drive wheels under load (higher revs). Therefore, besides high load springs, RacingDiffs LSD conversion set relies on Dynamic lock from ramp angles.

With these improvements, the RacingDiffs LSD conversion set is the most advanced LSD kit on the market.

The set contains all parts necessary for installation.

No more one-wheel spin on start, and sloppy turns around the corner!
With this conversion set, you will gain the true performance of a proper limited slip differential.
