onlyinajeep726 Posted July 8, 2014 Share Posted July 8, 2014 Any of you guys have experience running Rusty's Offroad fixed LCA's? The rubber bushings are shot on each end on both my arms. I purchased a master bushing kit from Energy Suspension about two years ago and only put the UCA ones in. The kit is designed to replace the bushings in stock arms, but I was wondering if anyone knows if these poly bushings will fit in the Rusty's LCA's?I don't particularly want to buy four rubber bushings at $12/ea + shipping from Rusty's if these ES poly's will do the trick. I just want to help with on-road manners for the time being before I go long arms. Link to comment Share on other sites More sharing options...
Dillithium Posted July 8, 2014 Share Posted July 8, 2014 For the love of Jeep, do NOT go with poly bushings for lca's if you plan on DDíng your pick up. I have fixed LCA's with poly bushings and I loathe them, they handle great but they pass on a lot, A LOT of road and axle vibration. I'm going with WJ LCA's in the near future, should be good up till 3'' of lift from what I've read. Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted July 8, 2014 Author Share Posted July 8, 2014 I appreciate the reply and I am aware that the poly bushing will transfer more vibes, but at the moment, I just need to not have it wander about all over the road. Just need to know if they will fit or if Rusty's got a proprietary sized bushing. Link to comment Share on other sites More sharing options...
89eliminator Posted July 8, 2014 Share Posted July 8, 2014 Rustys arms use an OEM bushing size. they should work. Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted July 8, 2014 Author Share Posted July 8, 2014 Sweet, that's what I was thinking that I had read somewhere. Funny though that I just swapped my stock UCA's and the 27+ year old rubber is still tight and the Rusty's ones are shot in less than 7 years... If only rubber bushings were that good now.

skidoo_j Posted July 10, 2014 Share Posted July 10, 2014 It has a lot to do with the angle your new arms are functioning under. The truck probably sat stock height for 20 years. During those 20 years the Lower control arm sat parallel to the ground, so the only force on them was typically vertical and would be absorbed by the shocks. Once the truck was lifted those bushing now get beat with front to rear forces and the bushings are absorbing that transfer of energy. I ran rusty's arms for 2 years and burned through two sets of bushings. I then dropped my control arm brackets and have not had a single issue.
