'78 Replacement shocks

What is their recommendation based on Gary?

Ride and handling.  The HD Bilsteins (B6) are softer than the Sport Bilsteins (B8). 

I would recommend the Bilstein shocks for your car. Probably HD's all around.

On my '80 I just recently replaced my stock AC Delco shocks with Bilstein HD's up front, and Bilstein Sports in the rear. I chose the sports for the rear since I have a stock FE7 steel leaf spring stack in the rear. Old shocks had zero pressure in them. 13k original miles and this summer was first time on road in 20 years. The ride now feels tight but the rear feels a bit bouncy, if that makes sense. Seriously considering putting in a single fiberglass leaf spring this winter, hoping it will eliminate the bounce. And by bounce I may be just describing feeling every bump in the road. This is my first Corvette and I just don't have anything like this to compare to.

I've had 4 C3's and found that KYB gas shocks are the best investment. Actual lifetime shocks. I've never had to replace a set.

My L82 '78 with F41 suspension owned over the past 20 years, came with worn out Delco shocks = BAD. Replaced with Delco = GOOD. Changed to KYB = BETTER. Then went with Bilstein = BEST.  Joe
