Rear Sag on New OEM TRD Lift

I just installed the OEM TRD lift and have a rear sag issue. The rear is about 1/2-3/4" lower to wheel well than the front. It doesn't sound like a lot but I can feel it driving and feels very noticeable to my eye. Anyone who has the OEM TRD lift have the same issue?

Did you install it or did the dealer install it?

It looks like the rear blocks were never installed, just the new rear struts.

 

I installed it. Rear blocks are there.

 

Can you show us some pictures of the rear leaf where the block is installed?

 

Time for an AAL. Ditch the blocks IMO.

 

Second this

 

On a side note what the hell is that buzzing sound that comes from under the gas tank? Stopped once I turned the key.

 

I am curious. The rear appears to be lower than front, but did you still get the desired or advertised lift in the rear? Maybe the front springs just need to settle? Not familiar with this lift, but just wondering if maybe the lift isn't sagging in rear and it's the other way around and the front is just sitting high.

 

Yeah, after looking at the pictures, the rear is fine. As clock11 said, something is messed up in the front. Give us some pictures of your front, did you tighten your front lower control arms while the truck was in the air, or did you put it down on the ground then tighten them up?

 

Advertised lift is 1" in the rear and 2" in the front. I am hoping it just needs to settle but it seems excessive. It is a sport so stiffer springs. Didn't measure before the lift.

 

stock your truck should be 1 inch higher in the rear. Thats why they sell it as a 2/1 lift, it just levels it out and provides a slight lift.

 

Oh and that buzzing noise is the leak detection pump. It just makes sure your gas tank doesnt have a vapor leak.

 

Do a few hard brakes. It'll settle the front .

 

I tightened them in the air but got an alignment before the new wheel pictures.

 

Nothing looks terribly off in the front there. I do know that if you tighten the front control arms while in the air they can stick causing what you have. The alignment shop should of loosened them, bounced the truck a few times then torqued them down.

Im not entirely sure here, but give it a week to settle, but it may end up being due to the sport springs.

 

Does something look minorly off lol... I didn't torque them to what they came as. Used two wrenches to break but only one to tighten so I really don't think its the LCA's sitting high on new bushings.

 

Not really, but I will let some of the more experienced suspension guys chime in on this one. Tomorrow you should get some more responses

 

You're not incorrect. It won't settle out on the front and the blocks aren't enough to even the truck out. I had read on several Wescot reviews that the funny ended up higher than the rear and especially on 2020 and newer trucks. Not sure what changed that year in the rear though.

I had bought the Icon AALs in case i needed them. I first installed the blocks with the front lift and drove it for a week. The front settled a tiny bit but was still higher than the rear. I installed the AAL's a week later and it brought the ride almost level (within 1/4"). I liked the ride better too but will say the AALs don't do as well towing a 5,000 boat as with the stock overload springs with or without the blocks.

I actually prefer the bed to be higher simply b/c you load the bed when going out so I'd still rather have it higher but I'll wait till i need to rebuild the shocks and do it right with longer travel and the RXT pack. I also have a Snugtop cap, some recovery gear in the bed and a matching spare so there's a little extra weight there too.

How that helps!

 

My mistake! I saw the TRD lift and assumed it was for the Westcot Pro lift. Just saw its not a Pro so I'm not sure on the results of this lift.

 

A better pic of the front shock/spring is needed. Focusing on the base of the spring (spring seat).
