I've seen other people have similar issues with Grizzly lockers and wheel hop and I'm wondering how they've handled them. Truck is my daily driver 2007 CCSB leveled with torsion bars lowered almost all the way. I have Fox 2.0 shocks and 72" Longhorn Fab Traction bars. I've never had an issue with wheel hop until after the Grizzly locker install.

During 2 wheel drive launches (straight) that induce wheelspin the rear end starts to hop violently. I've scoured the forums and have seen everything from clamping the front side of the rear leafpack, the backside, or both. I honestly just think I should have gone with a TrueTrac, or left the g80 in, as like I mentioned before, I've never experienced a problem with wheelhop.

Does anyone have a Grizzly in their daily driver that doesn't experience wheel hop during wheel spin? Should I start by adding a little more preload to the traction bars? Should I put back the G80 (it's in fine working order) or see if I can trade/sell the Grizzly and get a TrueTrac?

I'm such a research first, ask advice second type of guy, and I'd like to thank anyone who provides input in advance....it's much appreciated.

I have a 2013 Silverado RCSB with a 416 stroker that I also installed a Yukon Grizzly locker in and had really bad wheel hop afterwards where I didn't have it before. I went from a locked rear diff to the grizzly to make it more street friendly. I initially thought the grizzly was unlocking and locking causing the wheel hop so I disassembled it and removed the center piece that causes the left and right drive sections to disengage causing the locker to stay locked. I still had the wheel hop with it locked. I was pissed!!! I believe the wheel hop is initiated from the large slack that is built into the locker. The left and right drive pieces have to have the slack in order for the lock/unlock operation to work. I since installed a Torsen helical gear diff and now leave two solid black marks :) I'm sure the Grizzly is great for many applications but not mine.

Makes sense. I remember riding in White Lightning with a grizzly and caltracs. Mark had fixed wheel hop problem that was so bad that he described the marks in the road like a basketball dribble leaving rubber each time it came back to hit the street. When I ride in it, that was gone but it still had wheelhop that felt like a jackhammer in short hard hits. The caltracs were adjusted to achieve this improvement. FFWD to my truck - I did a Truetrac and expected to need to sort that same issue out, but did t have it with my long bars nor my caltracs now. I thought that it was because my truck is so much heavier than his, but maybe there's something to the above theory on the grizzly itself.
