I had them on my duster and liked them. I "upgraded" to hotchkis Fox shocks and am not impressed with the change. Maybe I got lucky with my exact combo i don't know. I can't say there is no difference, but I also can't say the upgrade was worth it.
The car is a 74 duster with 400bb, t56 trans, 1" t bars hellwig cromo front bar, delrin spring eye bushings, hd leafs, offset control arm bushings and a borgeson box. 245 45 17 front and 315 35 17 rear. I put the car together as a driver 10 years ago.
