Shouldn't bother the ride to much, its just for the left right control of the rear axle.

Now, harsh I do agree. Put polyurethane front and back on a 62 impala once.....Big mistake! Hard ride and constantly squeaky!

I have oem up front. Prolly go OEM out back on the truck arms too but that'll be a job for a shop with a press and an air wrench and a flame wrench backup.

I've been other places but they wore me out!
