RC 3.5inch level kit squatting issue

[DPQI4719]

I hired a shop to install a 3.5inch RC leveling kit on my 2022 Ram 1500 3.6L v6 about three months ago. The truck looked to be sitting higher in the front so I took some measurements. Turns out I was right and it’s sitting 1” higher up front. Unfortunately, I believe RC did not have a note, until recently, indicating the incompatibility of the kit with V6 models. I looked at the kit before the shop ordered it. The shop obviously looked at the kit before they ordered it. The fact that I don’t recall seeing the disclaimer, and any reputable shop would have noticed the note, leads me to believe it wasn’t there when we ordered the kit.

Anyway, here we are and my truck squats. I wanted to confirm my options. My idea was to simply replace the 2” rear spacer with a 3” rear spacer. Concern would be that the shocks are long enough to accommodate an added inch. Called RC and they think I’ll be okay with N3 shocks that came with the 3.5inch kit. Anything else I should worry about?

Of course, I’m also worried that the front was actually lifted 4.5inch instead of 3.5inch—is the new upper control arm that came with the kit even angled enough to accommodate a 1” higher lift than it was designed for?

what does your UCA angle look like?
if you're not offroading it should be ok, but if you want you can probably ask RC what the spring rates are for the front and swap to lower spring rates. but without the technical specs and measurements there's no way to calculate if softer rated springs will help or not. (this is why i hate RC and those 99 cent store level manufacturers... nothing technical is published or shared, can't even further fine tune it. but then again... people who do serious wheeling don't run RC)

Of course, if you run N3 shocks for the rear and the proper springs (not spacers, because it'd be a pain in the rear to put the spring in with 3" spacers... do your shop a solid don't put them under that kind of royal pain in the butt) it may push the front down a bit due to seesaw effect, but given that you're V6 and not v8 i don't think it's gonna make that BIG off a difference.

When I did the RC on my v6 I noticed the note about it not being for the v6. I called them and was told the cv angles might be too much if I were to use it because it would cause for more than 3.5” of lift. He advised me to get the m1 setup and since it’s adjustable to move the clip down 1 notch to compensate for the v6. I did that and got exactly 3.5” for the front.

Thanks for the feedback! I just took some pics of the front assembly (uploading attachments) and surprisingly the UCA angle looks okay. I’m now concerned about the angle of the CV axle. I think there is enough slack in the brake lines, but at this point I think the best option, aside from fully replacing the kit with another manufacturer, would be to swap out the N3 struts with the adjustable M1 struts.

@boogielander - this would avoid adding even more stress to the rear springs
@skyhawk42 - this would help alleviate the pressure on the CV axle. Did you just have to lower 1 notch out of the box? Do you happen to know how many notches there are, and which of them yours was set to? I will call RC again to ask the same question, but if you already know that would be greatly appreciated!

Also, for reference, I drove around the lot of my apartment and found a 5th gen ram to compare angles to. I’ll attach a pic of that as well.

Posted pic of CV axle of stock 5th gen ram in prior post—should be easy to tell which of the three pics that one is

I think there were 5 notches, but it’s been over a year so don’t quote me on that. Yes, I did just lower it by 1 notch from how it was right out of the box and that was RC that recommended that for the v6

swapping out the rear spring would do exactly the opposite of stressing the rear springs. swapping front springs to a lower spring rates would also not stress the rear springs, as you are actually decompressing the rear springs at ride height with no load in the back.

honestly, at this point, unless RC is willing to take what you put in back, that is probably the best option you can do. if RC is willing to take what you put in back, then go with the tried and true Bilstein 5100s and just leave it at 3" at best.

that CV does not look right at all.
