I'm thinking the valving is too stiff on rebound and possibly too soft on compression. I'm curious what others run for valving on this type of shock. Mine is a leaf spring(SS) car. Yeah, it's got a smallblock.

What tires are you using, how much power etc... Pretty hard to get a good solid answer when you don't provide much info about what you're trying to do with them.

Do you have a part #? Last edited by 440W8 Duster; 03/16/14 02:26 PM. 70 Duster W8 motor. 1.29 60ft 5.79 1/8 at 120 mph glide with 1.80 gear @3170 lbs.

A set of rancho adjustables would do the job as the car is 500hp, but I have clearance issues and would prefer a smaller body and also a softer compression. Yeah, it's got a smallblock.

I would pass... one set of valving wont cover all conditions

Caltrac Split mono and bar. Good luck I don't feel that the shock will work for you. You make to much power. Let us know how it works out, hopefully the slicks can handle it. I hope I am wrong.

Vi-king feels their rear shock with the aggressive valving option will compete with Santhuff shock.He said if they don't work for me they would take them back HEMI-ITIS has no cure.
