Iv got a xr4x4 lsd 7", do people use these on the avon? thanks

If it has the sierra diff on now it whould fit

Hi, it's just a bare chassis at min.

My experience has been that a tired sierra viscous diff has been the second best mod to mine, 888's being the best. All the other improvements like brakes, power, shocks, quick rack etc meant to make it potentially go faster are less useful.

Externally no differnet from the non lsd bolt on shaft diffs so yes it will fit.
