The frequent problem of preload shims loosening their spring load or being damaged due to overheating and poor oil usage means that replacing them when re-building your LSD is strongly recommended.
These shims are 30% stronger than the originals, so your LSD performance will increase significantly. Higher pre-load delivers better lock/traction.
They are extra hardened to 55 HRC for greater longevity and enhanced performance.
There are 3 different sizes. If you are not sure about the best fit, simply send us your VIN and we will check it for you.
