Hi all I’m a new member after some advice. I’m using a Sierra diff 3.77 for oval track racing and need a lsd for it. Crown wheel is 8 bolt. Standard Sierra crown wheel 10 bolt. Lsd will not fit middle of 8 bolt crown wheel. I could weld it to locked diff but that would ruin a rare diff has anyone no of a lsd that would fit this diff or had a standard Sierra lsd lathed to fit. Any help would be appreciated. Ian.

 

Bara Singh might know the solution. Bara motorsport 07970 197377.

a lot of people on here have swapped to the supra diff and many have used a 6 degree beam to improve traction / handling, would the rules allow that?

 

Hi thanks for the reply I race sierras so running gear has to be ford probably get away with an after market lsd.

 

ah, ok. I did wonder if rules would restrict the use. See what Bara says about lsd for yours.
