So, my F-150 has a stage 2 or 3 clutch, I forget which I bought back when. I also bought a LockRight branded “lunchbox” locker and put it in there because I was tired of the one-wheel-peel. I put a Solid nodular iron diff cover which tamps down the “clicking” but does nothing about the binding and banging. I’ve found myself clutching for sharper turns because it will bind up the driveline in 2wd resulting in banging and hopping and tire noise. I’ve gotten used to it, but it’s less than ideal. The rebuild of the F-150 will get an electric locker because the way I use that truck on and off road makes a locker ideal.
I also discovered that in low traction situations the locker has a tendency to want to push the truck in a straight line no matter what you do with the front tires short of engaging 4x4. So I end up using 4x4 a lot more.
My Choptop originally had a factory limited slip with extra clutches and that thing worked great until the 7.5” got tired of my antics and underwent rapid unscheduled disassembly. The only axle I had with the correct gears was an 8.8” with an open diff so I got my hands on a LockRight lunchbox locker and threw it in. It was a miserable experience in that truck, the short wheelbase and the lighter truck weight magnified the problems experienced with the locker. Then I had it refuse to grab either axleshaft a couple times within a few hundred miles. Opened up the diff and found that the locker was no longer in good condition, so it got yeeted.
A limited slip is the answer for street use. Period. Lockers and spools just don’t play nice on pavement.
