| | | Is There A Difference In G 10 & 20 Front Springs? | Joined: Aug 2009 Posts: 936 Likes: 36 old hand | OP old hand Joined: Aug 2009 Posts: 936 Likes: 36 | 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.

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

The is a 454, diesel, 350 & 305...they all used the same stock front & rear springs?

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.

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
