Fantastic alternative to the boomerang Review by Neecko
For a while now I've had clunking sounds from the rear end whether it be the ball joint or the rubber bushings tearing on the upper control arm. I got tired of replacing the the upper control arm (boomerang) and didn't want to spend more money on another part I knew wouldn't last. When I saw this, I got excited as it was the solution I wanted. Well built, solid, and adjustable. First drive in to work this morning and no clunking and a solid feel, eliminated a lot of vague handling on the interstate in a construction zone that was hacking me off. The only unexpected aspect (but after thinking about it, completely logical) is a little more cabin noise now that the rear end is solidly connected to the chassis. Highly recommend this or the weld on version as a long lasting fix for anyone who's had issues with their rear end. (Posted on 12/3/2018)
Strong and does excelent job as a replacement for the weak tri-link Review by Tom Evans ( tommudd)
Great addition to the JBA lineup of suspension parts for the KJ . This is a well built/ strong replacement for the stock MOPAR tri-link. No noise at all from any of the parts while on or off road. (Posted on 10/2/2015)
