i have a question for my 86 cutlass rear trailing arms? i have a 7in cups for the rear someone told me i could extend my arms the top 3in and the bottom 1 1/2in any info would help. thanks!!!!!

!!

any info will help thanks

for what i learned and experience for every inch and 1/4 inch to ur bottom trailing arm and double that for ur upper trailing arm. for example, i got a 4 inch lift, so i took my trailing arms to a race car shop and the extended my lower 1 inch and my upper 1 3/4 and it work out well. my tire is centered and my rearend and driveshaft are in straight line instead the angle use to be in. also u might have to extend ur driftshaft also which a race car shop does all the time if u have go shop in ur area.

We have just what your looking for.....


The long arms have R+L thread with lock nuts ,for fine adjustments after installation.. All the ends are machined for OEM bushings...... parts with bushings pressed in are available...
