I have a set of unknown boxed rear LCAs for 82-02 F-bodies. The LCAs are powdercoated black with no visible markings or stampings, grease fittings at either end, and resemble the boxed QA1 or Competition Engineering LCAs. The poly bushings are worn and wallowed out allowing the inner metal sleeve to have between 1.5-2mm of free play leading to a clunk on braking. The ID of the bushing hole on the LCA is 45mm, the overall width is 50mm. The metal sleeve length is 62mm, OD is 19.25, and ID (bolt size) is 12.75mm. I've contacted Energy Suspension, and although they don't categorize their bushings by size we found kit # 3.2125G that will fit the LCA ID but would have to be trimmed by 5mm each for length. Prothane's website has a similar kit, 19-609 with the same issue. I've also seen recommended here to use MOOG K6178 for rear LCAs, but unsure if by removing the metal sleeve they'll fit or even work properly where they are only fluted on one side. I'm not looking to argue the merits of poly vs rubber bushings on a street car, I just need to know if anyone has run into a similar issue and what worked/fit. I would personally prefer rubber style.

 

Those look exactly like Lakewood LCAs

 

Their tech support just closed 30 min ago but will be calling them tomorrow! If these are theirs hopefully they can point me towards replacement bushings.

 

Looking at the Holley website they're not available anymore. But there's the number 2142 on the bushings themselves. Honestly they look identical to the bushing inserts for my BMR k member.

Might be able to get them thru energy suspension

 

Already tried them and Prothane, nothing direct fit. Would have to trim the installed length by 5mm per bushing to fit the width. Someone had to make the bushings, even Energy Suspension said none of the suspension manufacturers do them in-house.

 

Ahh I see. Might be worth it to just buy a newer set instead of going thru the headache of looking for bushings that may or may not fit properly

 

Thought that too, I can find several tubular LCAs for $90-$120, but boxed style is $300+ and stronger. Given that poly only lasts 5-10 yrs there has got to be a replacement out there.

 

That's just another reason I'm not a fan of poly bushings, especially in that location.

 

I had a set of Lakewood arms that looked identical to these for 10-15 yrs. I had wheel hop while pulling out of corners w lots of throttle as the car hooked up. I replaced them with a set of adjustable arms w roto joints from spohn. The new arms completely eliminated my wheel hop issues. The car also felt so much better in general than w the poly parts. I think there is just too much binding w poly. The roto joints actually ride smoother.

 

This helped! I found an older thread that discussed the Lakewood LCAs and replacing their bushings, and am fairly confident my LCAs are the same. While Lakewood does still offer these LCAs and DID have a replacement poly bushing kit for them, they have since discontinued it. I did reach out to them and found they were supplied from a company called Patriot Gauges LLC in Kentucky. Sadly their only listed phone # now reaches a medical company, so I can only assume they are defunct. Lakewood did however say that they know Patriot sourced them from Energy Suspension, so I've come full circle. As I've already confirmed they don't currently offer any bushing matching the Lakewood specs, dead end.

I did finally find urethane bushings by Currie for their Currectrac control arms that match the Lakewood bushing dimensions exactly.
ES-2142 Control Arm Bushing. I'm going to call these good enough, and in the meantime put my 19mm OD steel sleeves into 21mm OD X 19MM ID x 1mm wall thick brass tube to make up for the slop in my old bushings and get the car on the road.
