The Hellwig kit (shown in previous post pics) provides parts to box the middle rails on the regular frame boxing it like a convertible, and it adds a additional mount inwards that helps with torsional stiffness. They recommend bracing the rails and adding a slight pre load to help with maintaining the dimensions, and to wled slowly to avoid warping. I haven't removed the braces yet so I won't know how well I followed that until I cut them off later this week, ha ha. I did take measurements throughout this fabbing and they remained consistent, which I'll take as a good sign. In addition to this I'm adding the following to the frame:
- bracing for the front lower control arm mount.
- gussets at the edge of the engine crossmember. my current frame was cracked here and I don't want this one to suffer this same issue.
- gussets from the middle rails to the transition in front
- gussets for the rear axle crossmember.
- gussets for the rear shock/ spring mount plate. this, being stamped sheet metal seems flimsy, especially as it's only riveted in some areas. I added weld to help strengthen them, too.
