Q & A

What's in the Box

These steel rear control arm bushings have spherical bearings in them, just like a rod end, which frees up suspension movements and eliminates binding. Fits '73-'88 GM midsize upper and lower rear control arms. 

Sold individually.  

Notes

This unit now includes black rubber inserts for both sides

to make the unit appear more 'stock appearing'.  Please note

that they can be removed to clean and disassemble and

re-assemble the spherical bushing as needed.

These bushings will unbind your rear end and make everything completely free. Squirt a little penetrating oil on them every so often and that's it for maintenance.
Yes, I recommend this product.

Very good product

May 24, 2014
I used this on a 91 camaro rear LCA , helps the rear end articulate around corners a lot more then stock or Polly bushings. The rubber bushings hold the bearing extensions in well. The only spot I wish they would improve on is having grease zerks so u could lube and preload the bearing slightly during normal wear.
Pros:
  • helps aginst rear end bind
  • Great price
  • improves traction
Cons:
  • needs grease zerks
Yes, I recommend this product.

better then stock bushings

March 12, 2013
This will deffently help you pro stock or street stock that just doesn't seem to have the rear end movement that you think it should these are the best fix for the stock 4 link bars and even if your rules say it has to be a bushing you can make rubber that will make these look like bushings
Pros:
  • more rearend movement
Yes, I recommend this product.

Do you sell rod ends for these bushings? Our rules allow us to run spherical bushings on metric chassis. We would like to build our own rear control arms utilizing these bushings.

Sorry we do not sell the spherical bearing that is in this bushing as a separate item. If the rules allow you to use a heim joint such as 15031008 or 15031208 you would be much better off both cost and strength wise.

To have a nice snug fit use 9/16" bolts with these bushings. Most of our customers typically use 1/2" bolts however. The 1/2" bolt will be a little loose in the bushing adapters but will not be a problem once bolted up tight into the frame.

These bushings are meant to be used on Street Stock and Hobby Stock cars. Without know your exact dimension on you ears on your rearend I could never guarantee a fit. If you could look at the dimension and compare them to what you have there it would help. The dimensions are as followed: · Hole through bushing: 9/16" ID · Length at center: 2.316" · Length at outside diameter: 1.955" · Outside diameter: OD of bushing has a step (as do original equipment bushings) Step measures 1.912" OD Rest of bushing measures 1.843" OD

Yes these will help any and all race cars that use this style of bushing since it will free up the suspension to travel without friction like a rubber or polyurethane bushing will.

If this spherical bushing is allowed by your rules then i would install them in all eight positions on the rear control arms. These bushings will significantly improve the articulation of the rear end and allow it to move freely.

Yes you should use some sort of lubrication such as WD40 or similar. Use the same lube as you would on a rod end.

Polyurethane 1964-1988 GM A/G-Body Rear Control Arm Bushings
(Part #91634045)
                        

Reduce wheel hop and axle wrap while improving the cornering capabilities of your 1964-1981 GM A-Body or 1978-1988 GM G-Body. Set includes bushings for upper and lower rear control arms.

  • Full-Floating, Non-Binding Design
    • Important when ride height is altered or greater suspension load is required
    • Especially important for both lowered and raised vehicles that have had drastic suspension geometry modifications
  • Superior Performance Over Time
    • Performance polyurethane control arm bushings do not rot or deteriorate from oils or atmospheric conditions such as ozone, smog, road salt, chemicals, and other corrosives
    • Will not deteriorate in a few short years and cause that mushy, uncertain response like rubber O.E.M. ones often do
  • Maintains Proper Pinion Angle
    • Weak rear control arm bushings will flex during launch and damage can occur to the U-joints
    • Polyurethane will flex, but it holds the rear drivetrain system in proper alignment

See Application tab to ensure these bushings fit your chassis. 

GM Midsize Offset Rear Control Arm Bushings
(Part #91634047)
                        

These polyurethane bushings have the center hole offset 1/4" to allow you to compensate for wheel or pinion angle issues. Fits 1965-88 GM midsize rear control arms.

Sold per pair. One pair equals two bushings. 

Seals-It GBTA1-09 Soft Control Arm Bushing
(Part #91034046)
                        
If your General Motors G-Body race or street car uses “stock” trailing arms, you need to take a look at this part! By using a softer elastomer bushing material in the upper control arms, you can significantly increase suspension travel and bite. This construction will satisfy many rule requirements requiring “rubber only” bushings. 

Fits GM G-Body Metric chassis (1978-88 Monte Carlo, Regal, etc.)  

IMCA approved for Southern Sport Mods only.
