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

The only people I ever hear rave about the Crap-Lok never lift a tire, ie street driving, icy roads etc. Personally I think they're total garbage. You can shim them to be more aggressive but it's never gonna near the performance of a $300 LockRite (course you'd need a new open carrier, but I think the No-Spin will fit the l/s carrier).

Maybe I'm wrong but given the overall direction of this BBS (rock-crawling) I don't think you'll hear many kinda words about any limited slip.

I know I'm not totally answering your question but if you do the type of 'wheeling where you lift tires (and it sounds like you do), don't waste any more time or money on the Crap Lok, it's just not a locker.

Yep. It doesn't matter how you stack or shim the clutches. A limited slip is worthless with a tire in the air. It's no different than a plain open diff. BOTH tires have to have SOME traction for it to provide any traction assistance.

A locker is the only way your going to get any traction with a tire in the air.

If you truely want locker performance you need a locker. Since you stated this is daily driver I'd go with an ARB.

Now I have a 92 Bronco with an Aurbun LS in the rear and ARB in front. It works great for its intended purpose. Daily driving, snow and ice roads vehicle. This was it's purpose and that is why I installed what I did. Having the front ARB was the best thing I did. It's there when you need it and most importantly only when you want it.

If I were to have decided that this vehicle would be more of a trail vehicle I would have gone with ARB's front and rear or a Detriot in the rear and ARB in front (to save some change).

my 3 cents.
