I take back all of my recommendations of JKS Bar Pin Eliminators
Background: I've run JKS bar pin eliminators (BPEs) since about 2004. The reason I got them is because the shocks from my Rough Country 4" lift kit were coming out of the bushings and clunking when off road.
I've since used them on two other sets of shocks - front and rear. My final opinion is that bar pin eliminators are merely a Band-aid fix for low quality bushings that are not tight enough. If you ever have to replace your shocks, BPE's will make that process extremely difficult. The rear uppers use socket head cap screws (allen key.) They will strip out, you will be cutting, drilling cussing, etc. I've had to do this twice.
Mine are currently rusted beyond any use. I had to cut them off. They are going in the trash. JKS will not honor the "lifetime warranty" because it is a "finish issue."
Advice: Buy shocks that have quality bushings that are pre-installed and you won't need to spend $100+ for BPE's. Avoid them.
and all the above is why I never recommend bar pin eliminators....also not surprised JKS won't honor their warranty either. if you think you need BPE's, something else is wrong with your low quality setup....
Strange? I've had them on the front of my TJ since 2005 and have been happy with them. We don't live in the rust belt though and that could be a factor. I did have to shim them with small O.D. washers to get the right "crush" on the bushings when running the RE monotubes. The Rancho 9-ways didn't need the shims. The rears are a different story and I wouldn't recommend them, largely due to the aforementioned allen head bolts. I can also see, that in some applications, they would be a mere band-aid to other problems.
