Differential drop options?

[BroncoDEPR]

Been looking for differential drop options and only see RC.... , what's everybody using, any suggestions are appreciated ? Currently running KO2 37's on Fox 2.5 coli overs on my 4dr SAS Badlands.

RC is the only one I've heard of. Demand looks to be pretty low but it seems like there's a little room in the market for a premium quality version. RC has only ever let me down.

I noticed the other day that superlift has one as part of their 3.5" kit. I contacted them to get some info regarding it and they informed me it would not be for sale individually.

Don't. Diff drops are not a good solution. You shouldn't be lifting an IFS that high to encounter issues anyways.

I saw the same thing and found Summit carries superlift replacement pieces. Coulnd't find any listings for the 3" lift components. The 5" lift diff drop looks like it requires the uprights.

The superlift 3" kit includes front and rear brackets. I think the instructions mention a spacer for the 3rd mounting location.

I disagree, the SAS package already puts the CVs at a angle at ride height. add 2" more lift or ride height and CV angle becomes an issue especially if you have a set up that keeps all of the available compression and droop travel. The CVs can and do bind and additionally the boots wear out MUCH faster.


A 1-2" diff dropped reduces the angle on the CVs and returns them to a near OEM condition at ride height.

on my setup Im using ford springs and factory shocks, and I have 12" of front wheel travel with ZERO bind 2" taller that SAS ride height and factory CV geometry at ride height. this is because of my diff drop.

as the video says near the end, a diff drop enables more droop than factory geometry allows for. I have 2" more droop than OEM. even with the ride height taller.

The part you circled on the right is the rear track bar bracket.

I have the RC diff drop bracket...its just a bracket and a spacer. Not much there for RC to F up. There was a member here that was working on one, but must have lost interest. Think his business is called AC fab?

@Oscargrouch323 i believe is his forum name and yes. ACFAB has one coming to market. In fact I think he brought a few to Colorado to install for people so go find him!

I’m trying to get my hands on one of his kits soon to run as I agree with @BigMeatsBronco 100%

thanks!

The front end geometric design envelope is pretty tight. Not much tolerance beyond SAS geometry. CV angles climb quickly. Surprised there is not more interest in diff drops. Hard to see how a small <2” diff drop doesn’t make good sense for >2” lifts (spacer or spring compression).

I’ve been waiting on the AC-FAB one also, but his last update on it was way back in May.

Yeah I was also waiting for more info on ac-fab diff drop. I thought the initial version only drops the forward two mounts but not the aft. ?? Definitely curious for an update.

I just spoke to him. Mods here banned him because people talked his product but he didn’t pay the admins a monthly advertisement fee.

Reach out to him on IG @ACFAB

Is anyone dropping the rack along with the diff to help those angles also?
Edit: Never mind I forgot about the effect on bump steer.
