I’m not sure if this will help anyone or not, but I’ve gotten so much info from this forum, I wanted to try to give back some. I recently purchased a 2021 Trail Boss LT, and just finished getting it level.
Here is what I ended up doing.
I went with the Rough Country 1.5 inch level instead of the Ready Lift 1.75. I’m sure the readylift would have been fine, but I read a couple things about it being bad for 4wd Auto and my thinking was that maybe 1.5 would be a little safer on the transfer case. Also, at 1.5, that I would have less of a control arm issue. Especially because the Rough Country kit did not include new control arms.
Well, I had the level installed, and I was not happy with the angles. I’m 99.9% sure everything would have been fine, but my 3 year old rides with me, and that .01% was driving me crazy.
I ended up purchasing the Rough Country control arms that are designed to work with their non trailboss/at4 3.5 inch lift kit. My thinking was, 2 inches from the factory, plus 1.5 level is equal to 3.5.
I just had them installed, and they are a tight fit with 295/70r18 Ridge Grapplers installed, but they do fit.
I’m attaching 3 pictures, from left to right it is control arm angle on factory ride with factory 275/65r18 Duratracs, then in the middle 295/70r18 Ridge Grapplers with RC 1.5 installed and factory controls arms. And then last picture on the right is 295/70r18 Ridge Grapplers with RC 3.5 inch lift kit control arms.
I’m satisfied with the angles now, and it could be all in my head, but I swear the ride is better now. I don’t feel every little crack in the road like I was.
Anyway, not sure any of this will help anyone, but figured I’d post it all in case.
Thanks!
