99-07 4WD Front Coilover Conversion
#153
Anyone manage to mount a 2.5" dia. coilover with a 4" OD spring?
Also, is it a clearance issue with these upper mounts gussets and the procomp style adapters being mounted crooked/sideways in all of the photos, instead of parallel with the frame/perpendicular with the travel?

They crooked to having to fit between the gussets, so yea I guess its a fitment issue, albeit minor.
Ok so I got the new new uppers in and tacked them together to mock up. Literally moved it as far over as I could. It gained approximately 3/4" of an inch more clearance from the UCA and raises the mounting point 3/4" from using the procomp adapter. The only bad thing is these will not work with the factory shocks, so if you decided to go back to stock you will need to remove these first. These should let lowered guys use the next size up in shock, or go approximately 1.5" lower.


I dont have them fully welded yet or powdercoated, but hope to by the end of the week. I would really like someone that has a 6" lift to test these before I order more to make sure they work. I only bought enough to make 3 sets. PM me if you have a 6" lift and want to try them, and Ill give you a discount

I've got a 6" lift and already running your lowers, but I need a centralized upper mount in the bucket (more similar to what the old Brenthel or Rockcrawler kits were). I will be running a 2.5" coilover with a 4" OD spring so it looks like that placement in the above pics would not clear the spring on the frame. UCA clearance is not an issue for me. Honestly if that is an issue for anyone I would suggest tubular UCAs.
Minimized stack height is a BIG plus to me though, that way I can get max travel without removing factory frame mounts and welding on raised mounts.

The spring on mine has a 3.5" OD, so if yours is 4" that is 1/4" per side. I have some clearance behind mine right now, and the frame has a little tab that comes outward that could be shaved easily. I think these would work for you, but you may have to grind slightly on the frame for the clearance you need.
Otherwise, will the uppers you have not work with tubular UCAs? I guess im not understanding what you need.

Well, I want reinforcement for frame, but not at sacrifice of travel like your original uppers and adapters. Would like to eliminate my adapters but also have stronger mounts. I also need to retain placement of upper bolt for some shock hoops I already have, as additional rigidity.
Do you have a photo of the Brenthel upper mounts? I guess I'm looking for something like that but bolt in. As high up in frame mount as possible.

Nothing broken, never said there was anything "wrong" with the adapters, other than the added stack height. I have Synergy adapters by the way, but nearly identical to the Procomps.
Maybe I'm not being clear, but basically want stock placement, but added strength like your upper reinforcement plates but without the added stack height of combining your plates along with adapters. If you had some of your original reinforcement plates but with incorporated upper shock mounts placed as high up in the bracket as reasonable (just under bolt in stock location). That way I'm not reducing shock travel. I am not getting much bump (up) travel at my height with a 6" travel coilover, so I'd like to maximize that without going down to a shorter coilover.
Looks like you are already hybridizing the two here into 1 pc, which I like, but you are also altering the placement, which I do not need nor desire.
Here are images of the old no longer produced "Chase kit" from Brenthel posted by black04 on here in another thread:

Ah, I see what you mean. The thing is I dont there is a big enough market for that to justify making a run of those. I basically have to sell most of the batch to recoupe the money invested in the parts, much less that time, and I dont know if those would sell since its a very small niche of an already very small niche.
