Front Coil Springs & Shocks Replacement - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ralph (1970 GMC) · 12-10-2013, 05:26 PM

Due to rust I'm replacing the front coil springs & shocks on my 1970 GMC (1/2 ton). 25 years ago I replaced the straight 6 (250) engine with a V8 (350). I actually like the way the front end sits now (which seems standard height - please see photo) and want to replicate it. My concern is what to buy :

Coils : standard or heavy duty, and do I need a 'drop' to compensate for the motor (weight) change and the coil 'sagging' over time ?

Shocks : standard or heavy duty ?

Any advice & recommendations is greatly appreciated

What are you all using on your trucks (particularly 1/2 ton with V8's) ? Any advice & recommendations is greatly appreciated

I have CPP 1" drop springs and Monroe SensaTracs. They feel great. I also have CPP drop spindles but you won't need those with a factory stance, they don't effect the ride anyway.

Here's a good link for some different coils that helped Dero make his decision. Good info on coil loads and heights:

Should I go with a drop in the Coils and do I need Heavy Duty one's for my truck ?
