Speedway Motors 91634046 Details

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.

G-Body Soft Control Arm Bushings make yo

We saved money by buying the Speedway brand. The quality is excellent and they work perfectly. One caution for those of you that have never worked with soft bushings. Make sure that ALL other components of your rear suspension are completely secured before attaching the softies. We put them in first during construction and ripped one by over extending it.

Bushings are good for bite but do not la

I would not recommend the bushings unless you can replace them every other race. They do not hold up for more than 2-3 races. I for one will not purchase them again cause they just do not last long enough to keep the cost of the car down.

Would you use this bushing in the upper trailing arm or use them in the upper rearend bushing? Or would you use in all 4 locations in the upper trailing arm and upper rearend mount? So buy 2 or 4?
