Lowering 70 C10 long bed ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

If I want to lower my 70 3" in front and 5" in rear, can I get away with just doing springs and shocks or do I need anything else. Thought I read somewhere if you go 5 or more you needed something else. Forgot what it was. Any help would be appreciated. Here is a picture of what Im working with. It is sitting with a 2" drop in the rear now to make it level. Thanks again for any input.

I would recomend a bolt in c-notch and adjustable pan hard bar in the rear, to go with springs.
Up front I would use spindles and springs, makes for a better alignment.
New shocks all the way around.
I run a similar set up on my 72 blazer just only 6 front and 7 rear, and I am vary happy with the way it rides and handles.

A bolt in c-notch will NOT be required for a 5" drop.

3/5" drop:
3" front drop springs
5" drop springs
Lowered Shocks
Shock Relocators
Super Trac Bar (AKA adjustable panhard bar)

That is all you will need, guaranteed!

Your right, not required. I never said they were required. I said recomend, with a bolt in notch you can regain some of the lost suspension travel. Therefore allowing the truck to still be used as a truck.

you can go w/o a notch with a 6" drop in the rear, but it will only leave you with about 1.5 inches of travel between the frame and the axle housing. i am currently running 4" drop springs, adjustable pan bar, shock relocators, new shocks and 2" blocks that i made from square tubing on the rear. In the front 2" drop springs, 3" drop spindles, and new shocks. hasnt bottomed out yet but i drive it slow and easy on rough roads.

just to let you, my brothers 71 dropped 5 in the rear when we installed 4inch McGaughy springs.
