Has anyone rebuilt their Ford 8.8 LSD and shimmed it up to have a better performance? I know there are many different choices for traction devices out there for this rear end but im wondering if I could get marginal performance out of current one. First off it has 45K miles on it so it’s in need of a rebuild. Second im running 33x12.5 BFG MT’s so it has to deal with increased wheel weight and traction off road. This is my daily driver also. I did a test the other day by crossing a ditch and having one-rear wheel in the air and one stuffed 100% in the wheel well. I noticed that the one wheel on the ground was giving almost no power and the wheel in the air was spinning. What I want to achieve is to give that one wheel on the ground more power. So will this work? Its been brought up to me many times but I haven’t heard from anyone who has done it.

Thanks
