I seem to burn through rear bumpers in months. This is my third one this summer lol. Some of the extra parts come in very handy if you hold on to them.
I used the brackets from a 2wd slash rear and the plastic wheels only because my truck is blacked out. As you know, we have a red or blue alloy option that comes with bearings. I also took the rubber wheels off my alloys so I don't hear that ssscccrrraaapppiiinngg sound as they drag down the street.
If you try to add the wheels on without a spacer, it'll hit and rub the plastic bracket your adding on so I used the lil plastic standoffs from top off the shocks the small end fits in the wheel and the bigger end gives some space to rotate. Just use some washers and lock nuts to hold your wheel assembly together but don't go to tight or your wheel will bind. The other 2 holes will thread with a standard screw from your extras pile.
Im going to run it like this to see how it does but I think i'll be adding a cross brace between the wheels and ditching the lock nuts. Just want to see how much flex it has first. I think it'll be stronger with the extra brace.
This is how much lift you'll get with this set up. Looks like it's plenty for my needs.
