Thread: nearly new Ford trac lok not working on ice?

    I've gotta do a better street test but I did a short brake stand in the driveway and only one spun...the passenger side rear. My experience in the burn box at the drags is that pass side rear will spin then the driver side will catch up. Kinda sucks. I'm told I'm probalby too heavy and powerful (over 700 HP to the tires) for a stock trac lok. Mine came from Ford Racing so it should have the carbon clutches...but doubtful it has the extra 2 clutches. Also doubtful it was set up tight. True Trac has been recommended at about $580, I did look at Torsens but they're more like $700.

    That's what I thought, I wasn't buying their bullshit. They made it right though, so whatevs. But, I believe I compared it to my Firebird or Town Car and yeah, I couldn't spin the a wheel by hand with the opposite on the ground. At least not without serious effort, can't recall the details..

    Well, if you've been ragging on it like that for awhile, the clutches are probably smoked now. Even with 700HP, it should still work both wheels, or at least try to up until the point it turns into a grenade.

    I'd expect the diff to blow up before the clutches had a chance to wear out at that power level.

    It you are powering out of corners, you ain't doing the clutches any favors. But something to keep in the back of your mind as a wear item if you like getting on it in anger around corners, the diff is going to try and diff and it will somewhat succeed, and succeed more as the clutches wear to the point you end up with a peg leg eventually.
