2014+ Leveling Kits

Big Whiskey · September 25, 2015

Hey guys what's the likelihood for the rear axle to shift when installing new lift blocks? And if it happens, how do I fix it? 4 wheel alignment? Unless I'm seeing things it appears my passenger rear is shifted forward about 1.5" compared to the driver side rear after I put in new 2" blocks. At least that's what the tape measure is showing me. Thanks.

There are holes in the block and dowels where they sit.. If the installer didn't line them up correctly it's possible. They only go on one way. You would have to loosen the u bolts and position the block in correctly

This. To the OP, can you tell if the blocks and u-bolts look the same on both sides? The blocks are probably tapered a little to adjust the pinion angle. The shorter end should be pointing towards the front of the truck. You should have the same amount of u-bolt coverage on both sides. And, the blocks have a centering pin that will make sure they're sitting on the exact same place on the axle. If any of these things are off, then your axle may have shifted.

Thank you for the reply.

We did make sure the taper angle was larger to the rear and all the pins line up. The one thing we didn't do when installing the blocks was to disconnect the lower shock bolts. Not sure if that really matters or not. But unless the actual truck bed is off square with the frame, the passenger rear tire sits more fwd than the driver rear tire almost 1.5". Thrust angle seems off a bit. Anyone know if this is corrected with 4 wheel alignments? Seems to ride very nice still.

BTW new BFG's going on today! Finally!

Well, if it none of those things...then I'm out of ideas. May have to take it to an alignment shop. I wouldn't think the bed would be off that much. Have you measured from the center of the front wheel to the center of the back wheel on both sides?

Haven't measured yet. I will tomorrow. Alignment report shows the thrust angle is off some. I'll post it tomorrow with some pics of new set up. Thanks guys.

Keep us posted! Good luck!

Ok so here's before n after pics.

Before: Stock height front = 36.5", Rear = 38.25"

After: 2" RC level front = 38.75", 2" Ready Lift blocks rear = 40.75"

& BFG AT KO2's (275/70x18). Truck now sits approx 3.5" higher. I like it.

As I mentioned before, this is my winter setup. Next spring will come 5" RCX lift and new 20" wheels n tires.

Ok so I measured front center hub to rear center hub. Here's what I got.

Passenger side = 143"

Driver side = 144"

Definitely a difference. And here's a copy of my 4 wheel alignment report.

So now what? Seems off by a degree?

im thinking about putting on toyo mt's 275/65/r20 with a 2inch rough country leveling kit. Went to my local dealer and they said it would fit with no scrubbing. id like to know what you guys think and your opinions on this. i want the biggest tire i can run, with no scrubbing or needing to cut anything out. im just curious because some say they will and some say they dont. if this size is to big then what size do yall recommend. like i said biggest tire with no scrubbing.

Got the level lift finished

Did they srub or rub anything at all im thinking about running the same size tires on my truck. Ive got a 2inch level on mine and was told these size tires wouldnt scrub. Have you had any issues?

Hey bud! I had a little bit of rub at full lock, so I had to zip tie the felt back in the wheel well and now I have zero issues with rub. You will not be disappointed!

I'm stumped dude. Did the alignment shop offer any advice? At least your truck looks really good, lol

For those of you with the RC 2.5" leveling kit, did you have any issues getting the camber back to where it is supposed to be? My shop guy is worried about getting the camber back to 0 (or whatever it is supposed to be) after the 2.5" Rough Country. I'm not sure if 0 is the right number, and I'm not really familiar with where everything is supposed to be. He's suggesting the Fabtech 2" and prefers Fabtech since he believes it is a better product. I really like the look of the 2.5", but am wondering if I should take his advice, even though lots of people in this thread don't seem to have any problems with there 2.5" kit.
