Review: Worth it 9.5gm 15 bolt sf - Works perfectly in my gm 9.5in 14 bolt semi float axle for my 93 blazer. Read the instructions i installed it the hard way with the springs and pins installed when putting it into the carrier instead of slipping them in thru the side as it was designed. I got it for 367$ which beats summits price by about 300$ engages smoothly under load when I want it to but it is rough on the locking and unlocking when idling in gear thru parking lots but I think its only because its a manual. Seems pretty stout and fit with the original thrust washer shims that it came with and the cross pin fit better then the original. We'll worth the money. I might even consider one for my c1500 with the same axle for a street truck as the street manners is better than expected unless you're hot rodding it thru the turns then it'll chirp the inner tire or break both tires lose
Review: Works fantastic - Pros -it works great off road and in the snow, totally locks the diff up, easy to install. IMPORTANT axle end play specs, set them right!! Wife drives the vehicle and doesn’t notices it. on road works well also. Cons - install manual sucks, clunky at times, hard on tires. It is easy to install. Unfortunately in the Chrysler 9 1/4 diff I installed this on came with Posi case. And the original part I ordered was the one for the Posi case. I didn’t fit, called tech support to verify I had the right part, they were quick to help. Unfortunately I had to order this locker along with new open case $135 new spider gear set $70 “just for the shims” the backlash adjustment tool $25 bearing set $100, fee to get the bearing pressed on $40, and backlash gauge for $30. I installed this on a 1999 Durango 4wd. The installed required a lot more work also had to weld the abs/speed tone ring to the case because when installing the original ring gear to the new open case. The tone ring had enough clearance to spin free. Time consuming and annoy. But the locker works fantastic. On road it’s mildly noticeable clicking around turns and clunky at times. But overall not a big deal, my wife drives the Durango often and has never complained about it. Video upload was with vehicle in 2wd.
