Front and Rear Control Arms & Polyurethane Bushings

[91RS]

You’ll probably have to spread them out to get the arm in.

@signguy62 I did not run the DJM trailing arm relocation brackets in my setup. Sorry I couldn’t be of much help with that…

I would think @91RS suggestion could work as both parts are designed for stock OEM mounts and hardware.

Reviving an old thread...
So you are saying the Sponh boxed lower trailing arms with poly joints will fit the DJM trailing arm relocation brackets?
I have the DJM kit installed and I purchased the Spohn boxed arms. But they don't appear as though they'll fit. The Spohn poly bushings don't want to go into the DJM brackets.
Any guidance you can provide would be greatly appreciated.

Thanks!

I ordered the Spohn kit (GMSUV-07-RK1) and it fit perfectly. Everything fit - I had a suspension specialist do the install since he is used to working on cars set up for the track. You don't need the DJM kit for it to work. The delsphere's on the Spohn kit relieve any possible binding.

I'm on a 4" drop out back and its all adjustable. Rear end is ridiculously planted. The ride is a bit harsher than I had hoped but she stays put. I started doing AutoX with the Burb this year and even the instructors were impressed with the big girl's handling.

I just bought @CMoore711 front UCA/LCA that he started this thread with. I'm gonna try and improve upon his idea and see what I come up with.

Wish me luck.

Just wanted to provide an update to anyone that may be interested in going with the Mevotech A-Arms and the Prothane bushings.

@CMoore711 was at the 1 yard line - I just took it in for a goal.

After consulting with my suspension guy as well as my mechanic, they both suggested I get someone to machine the proper bushings/sleeves.

OD is 1.030"
ID is 14mm as stated in the above thread.

Took the sleeves and measurements to a machine shop and voila! I'm $260 lighter but I have what CMoore was going for. Here are the units and here are them pressed in. I did not take a measurement of length. I'm going by what was posted earlier about them being the perfect length. I have some more parts I need to line up for my suspension but I will post a pic once they are installed and do a review. I'm interested in seeing how they fit and if there is any noticeable noise that OP was talking about when he did the "sleeve in sleeve" solution. I am hoping my outcome is better.

Will keep you posted.

Those are some nice looking machined sleeves, hopefully this is the answer to keeping them quiet and mounted snug.

All Done!!!

Mevotechs with the polys are in, along with my newly machined sleeves. Everything is tight and noise free! No clanking and no squeaks. A noticeable improvement in handling and I saved about 12lbs per side vs the factory stamped steel units. I replaced the swaybar end links with DJM poly's and they were a lot shorter too which also tightened up the front. I am awaiting replacement bushings from Eibach for the front sway where it mounts to the frame. That's the last thing to do. I am super excited to take this thing to the track now.

Wilwood came through and replaced my rotors and pads at no charge with a softer compound brake pad so the brake chatter would go away. Looking for some lightweight 20s or 22s with a custom offset so the wheels get pushed out a little further, and that should finish up my prep for AutoX season. Lots of trial an error from @CMoore711 and myself but I think we got everything we need now for a full poly/handling setup for our trucks.

Last thing to do is find someone making Poly body bushings. DM me if you want a parts list of everything I have on my truck. Lot of great info in this thread as well.

 

[CMoore711]

This set-up looks great @fozzi58! Glad to see the bushing sleeves you had machined worked out better; Having all new sleeves machined vs. inserting a sleeve into a sleeve made all the difference I bet.

Really glad to see Wilwood came through for you on some new rotors and pads at no charge! That's huge.

I bet your burb feels so much more solid and planted now.

I haven't driven it hard yet cause I am waiting for those replacement bushing for the front sway, but yeah its a noticeable difference. There's a little bit more harshness in the suspension but I am OK with the "Corvette-ness" of the truck. Looking forward to pushing this thing around some fast corners!
