Just FYI, both me and moose have modified our Frankenlifts. I've lowered mine and Moose had to add bumpstop to fix the UBJ problem.
For being a kit sold to average users it shouldn't have these problems. Alot of people do not know where to start or look for these problems. They maybe relatively minor to someone that wrenchs on their Jeep regularly, but to some they are a big deal. If you know what to look for and how to correct the issues, they are minor. But some people do not have a garage, the tools, or knowledge to correct these issues.
That is why I would recommend Rustys to someone that wants a set it and forget it kit. I believe the Frankenlift uses better parts, but issues need to be addressed. If you don't mind tinkering with your Jeep the Frankenlift is a great kit.
DesertKJ you can still salvage the issue.
- First, you need to check to ensure the lower extension bumpstop is still in place. When I first got my Frankenlift it was not held on very tightly and slid off. Luckily, I caught it in time and was able to patch up the UBJ boot.
- Second, it will settle some but not THAT much. Maybe 1/2". However, your CVs and boots are more resilient that most people thing and will take a beating. If you are still not happy with the height, you can disassemble the strut and shave some of the spacer down. If you have the rancho struts you can slide the clevis up past the lift and loose about 1/2" of lift.
- Third, if you are not happy with the front and rear height discrepancy you can add an extra upper rear spring isolator. They cost $10 a piece at the dealer. You will need two, one for each side.
