Mazda - LSD conversion set

Forget about the one-wheel spin! With our Progressive LSD Conversion set, you will no longer suffer from losing grip!

We currently offer LSD conversion kit for NB model (1997 - 2005). Other models are coming soon.

The set is mounted on your standard differential, transforming it into a clutch-type 25% lock limited slip differential. 

The set contains all parts necessary for installation. 

There are 2 key points which defers our kit from any other on the market:

1. NO material wrapping. We decided to make NO compromise on the material quality. So our plates are made from the highest quality tool steel, heat treated and nitrated to achieve the highest wear resistance. But that wasn't enough. We added Friction discs between plates and spider gears which are made from the same material as our LSD clutch plates. So we successfully stopped metal shavings which is the biggest problem of cheap LSD kits such as Phantom grip.

2. Increase the performance to the maximal level. How we did that? The answer is in the name - Progressive LSD conversion set. The main goal was to achieve the progressiveness. We 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). This Video shows how it works. So besides high load springs, RacingDiffs LSD conversion set relies on Dynamic lock from ramp angles.

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

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.
