Pull the rear diff cover and weld the spider gears together locking the rear end up. It’s a game changer in how it will perform off road, I welded a few buddy’s up and it was a night and day difference. The last guys had a third member requiring a bit more work but it still worked like a champ. I ran spools in my Sammy’s but only because I regeared them and I had them completely apart anyway.
Bust out the spray paint and make it a sweet little rig
