Leveling a Trailboss -- Drop Rear

[Derthax]

Has anyone swapped out the 2" blocks with 1" to level the trail boss?  If so, any issues? Any photos?  I need to level it -- but I don't want to raise the front.  Give me the good, bad and ugly.

I have not, but I see no issue with that. When i lifted (2") my previous RST, I experimented with 1" - 2" blocks and ended on the 1" block in the rear. Looks good.

I wouldn’t if you plan on towing anything

Go for it.

I pulled the rear lift blocks, shocks, and 2" bump stop spacers. Basically just removed the rear lift so it is the same as a non at4. I had 2.5" piggyback kings from my 2011 silverado and they bolted in perfectly. Make sure to get new u bolts. Also needed to adjust the headlights slightly- about 1/4 turn downward. End result was all fender heights are within 1/8" of each other.

I'll likely do this as well.  Swap blocks to .5 or 1.0", get new u-bolts, and done.

cheapest and safest way to level - we're already at 2" front.

What PN did you use for replacement shackles?  I talked to the dealer and they were being weird about giving me the proper number; said they HAD to order by VIN.  I almost walked into the lot and found one without a lift and gave them that..lol.  Also wouldn't tell me if they come individual or in pairs.

I didn't replace the shackles. Just removed blocks and bump stop spacers and replaced shocks with shorter ones.
 

I haven't looked at the shackles on this truck, but I did change them on my 2011 and it was not a fun task. I would avoid it, if possible. Removing the blocks, or going with shorter ones, is a better alternative since you also decrease the chance of getting axle wrap.

Removing shackles is easy-peasy, don't be scared of it.  You can remove and replace the rear blocks/shackles (4 bolts on each side of the vehicle) in less time than it takes to sit down and drink a soda.

I meant U Bolts.  What PN did you use for the replacement U Bolts and did they come individually or as a pair?

[Justinv113]

You can order them from an offroad/automotive shop of your choice. 9/16" square ubolts. Width of springs are 2.5". I think i got 7" long bolts and had to cut off around 1" after torquing everything down. Paid something like $40 for the set.
