🚗 Detroit Locker 913A561: Trutrac Differential for Ford 8.8" with 31 Spline - High Performance Upgrades Review

Absolutely love it, build it on my f150 and now I can fry both tires when turning or have 1 wheel spin faster so it doesn't pull on the wheel like a blocker.

If you have an open differential in your F-150 this is a great way to increase traction. Installation is easy and takes less than two hours. When installing I would replace the bearings and seals.

Wow! This Detroit locker is worth every penny I spent on it! I mounted it on my Ford F-150 pickup with 6 cylinder engine. Doesn't matter! Now I'm craving like never before! I highly recommend it. In addition, Locker fits very well in my truck. Installation was pretty easy too.

Update: I've been using this diff for a few years now and it's been flawless. Lots of road miles, countless drag strips, over 930 rwh and 9.90 @ 145 in a 4000 lb GT500. I will switch to 33 splines and use TrueTrac again. I have used many of the diffs currently available and this TruTrac is by far the best. It's incredibly durable, completely silent and easy to install. So far I've done 10.30 @ 137 on a 3950 lb GT500 with this diff. I've also ridden it in autoros and many kilometers on the road,

The differential itself is amazing. It's amazing how subtle it is until you need it. No disadvantages of a breakfast locker, but many advantages. I drive my truck pretty hard sometimes, even on the road and cornering it behaves like an open differential until the inside slips. You only feel it briefly when the power emerges and pulls you along. No crazy jams or wheel hops, chirps or anything else that would upset the balance, it just stays nice and smooth and stays in control. Love it, even in…
