‘21 Diesel w/ Mopar 2” lift. Bad Front Rake.

[2TH MVR]

Just like everyone posted. Add a front spacer. Had the dealership install the spacer same time the mopar lift was being installed.

Although there are a number of cheaper options, these are very high quality with dead simple caster adjustments for 1.5” on up to 4” which require rotating a slotted washer vs removing bolts and shifting the brackets etc.

I get why there is rake. These trucks squat around 2 inches or so with a loaded trailer.

The Mopar lift has to work with any condition.

The Teraflex Spacer kit works great IMO. You might want extended bump stops to do it right though.

Mopar lift with 1.5” tereflex pucks. I had .5” puck in initially but added a bumper and winch then I had to put the other puck in.

Yeah but is yours a diesel?

It's not required necessarily, it's more of a preference. It just adds Caster which reduces bump steer, putting the jounce into the suspension rather than creating feedback into the cab and steering wheel. The additional Caster appears to make it track straighter & it seems that my Gladiator requires less steering input to drive than it did back when it was stock.

Yeah, I totally know what they do and why they exist. My JK was almost undriveable when I added the 3" lift, until I added the brackets, then it drove better than stock with the different spring rates and shocks dampening. I just kind of assumed/thought the new arms that come with the Mopar kit would have brought the caster back to where it needs to be...that's kinda the point of new arms, right?

If you just do the MOPAR lift, the new LCA's are designed to bring you back to stock caster. Others, like @HighTork (and myself) also added the spacers to the front, which brings it back out of spec.

Also, the stock caster is a little "light" IMHO: the geo brackets not only give you back some caster but also help with the angle of the LCA's which helps overall ride feel/quality.

100% agree regarding the new LCA's. The new LCA'S however, only put you barely within spec. Once you add an additional inch of spacer on top of the spring (seat of my pants quote here) you can in some cases tell something is off. Far too much wander for my comfort. I feel there is a bit more exaggeration with the diesel vs gasser. My associate has 3.6 and his didn't seem nearly as bad as mine had been. We lifted a week apart.

Absolutely agree. I'm no expert, just a fella who's had a lot of Jeeps over the years. And this truck without correction after the lift and spacer without adjustable LCA's (my opinion here) seems a chore to drive on longer trips. The drop brackets to me, offer additional benefits by decreasing the angle for better bump intrusion through steering. The energy is transferred to the spring & shock vs feedback through the rest of the steering and suspension components.
