I’m wanting to purchase RLCA (adjustable) for my 85 Tbird. CHE are a little less cost. What are the difference between these and Maximum Motorsport design. ? Anyone here running these with good results?
I believe CHE advertises the lower adjustable will raise the rear of the car 1/2" with the same springs.
I have the CHE adjustable on my car and changed my rear springs to Moog CC821 that are shorter springs. I am happy with the ride.
How long have you had the CHE units? Are you satisfied with them? They are less money than the other brand. Can you post a picture of your car? Curious about the ride height.
Thank you
I've had them on the car since ealy 2020 so two seasons on them. I did the upper and lowers with CHE.
My old control arms were completely shot so the car drives like a different car and so much better.
I am at stock ride height.

Car looks great. Like the wheel choice.
Hi Mike, car looks great, I miss mine. Did you get a lot of snow last Saturday? We’re getting a lot of sunshine here in Florida!
ISTLCRUZ, I had non adjustable Maximum Motorsports lowers on my 88 and boxed the uppers myself and replaced the bushings. I was also fortunate to score some Koni NOS lowering springs back in ‘01. I don’t think you would go wrong with the CHE ones.
Hey Rick! We got about 9" but I think your place got more being further east. Eastern CT got something over 1' to 2' so guessing Rhode Island got it worse. I am glad to hear you got some sunshine down there after that cold spell. I have not done much to my car this past year since we met. I've been riding more instead even got the studs on now.
ISTLCRUZ - Like Rick mentioned, I don't think you could go wrong with either choice. Find out the backorder time and go from there?
I run Maximum Motorsports extreme duty adjustable RLCA and stock uppers with new bushings. The lowers have spherical bearings on each end, so you want the stock uppers with rubber bushings to prevent binding in the rear suspension.
Just a FYI if you go with the Maximum Motorsports RLCA.
The spherical bushings on both ends of the RLCAs allow for all of the articulation that the rear susp. needs. Poly bushings are what can cause the binding.
Rubber in the uppers will help with some NVH, but aren't required to reduce binding.
I asked Jack at MM about putting poly bushings in the stock uppers or adding tubular uppers with poly bushings with their control arms and he said not to. I'd have to find the email conversation but it was related to them causing articulation issues, even with the spherical bearings in the lower arms. Stock uppers with rubber bushings were what he recommended. Jack knows his stuff so I did what he recommended ;).
I had poly bushings with my CHE arms, plus some sort of metal upper axle end things that I foolishly slapped in as well. Rode rough as hell, the susp was bound up, and even on slightly rough surfaces, cornering would cause the rear to kick out as if it were a leaf sprung truck.
When I did the Mustangs later on I left all the bushings poly (but did put new ones in) and they all have ridden so much nicer.
Lessons learned...as they say.
Your post was worded like the spherical bearings in the lowers was the issue, not poly in the uppers. ;) (You didn't mention poly until now). And yes, Jack for certain knows what he's talking about.
Yeah, poly bushings feel great...right up until they don't. Then you're skittering off into the ditch.
You need some sort of allowance for articulation in the rear suspension.
Yeah it came out kinda confusing. I was trying to explain that with the MM RLCA you want to keep the stock uppers and rubber bushings so the suspension continues to articulate correctly. Don't add poly bushings to the stock uppers or replace them with tubular uppers. Just don't use poly bushings in the rear suspension period.
Thank you everyone for the info. That helps a lot. My car isn’t a daily driver or high H.P car so I will probably go with CHE. They are less costly and they offer a 10% off thanks to Eric & CoolCats!
