looking into a way the “soften” up the ride on my 91 G-20 shorty. Wondering if anyone knows if there is a difference in the stock front springs between the G 10 & 20 vans?
Thanks


Recently purchased (10-2021) a 1991 Chevy G-20 “Shorty”. Past vans are a 1976 Chevy G-10 (purchased new in 1976 & sold in 1995). A 1978 Chevy G-20 Shorty purchased in 2010 and sold in 2015.

There about the same ... it depended on which motor was put in at the factory ..

Big motor G10 or G20 one set of springs and a 4banger or I6 in a G10/20 a different set.

What do you mean by "Big Motor"? The is a 454, diesel, 350 & 305...they all used the same stock front & rear springs?

Well a 454, a diesel or a 350 weigh more than a 305 or a I6 and the factory would have put in thicker coils. NOT ALL VANS WERE MADE THE SAME. Maybe the rear has the same leafs in a G10 and a stockier for G20's and even heavier for a G30 .... but the ft is a whole different animal.

If they had put a 454 in a G10 the ft the factory would not have put in I6 coils. A 454 would crush a set of I6 coils.

My experience with Chevy vans has shone that G10 front springs are weak and allow a lot of bouncing and the body can come down and hit (cut) very wide tires.
G20 springs are firm and the body will not hit the wide tires. I learned this lesson in the 70's with my first Chevy van and I added spring spacers to fix (sucked).
My current 77 Chevy shorty is a G10, but has the optional HD springs front and rear which are basically G20 springs and never hit my tires. Hope that helps
