Re: ‘78 K10 Suburban Suspenders... er... Suspension!
Ryan,
I have a 1990 V2500 (K20) Suburban that I have been driving for the past few years. My suburban was a 3/4 ton 4x4 that had the double shocks up front. It was a very rough ride. I worked with Deaver Spring ( my office is only about 5 miles from their shop) and I went with their 4" lift progressive rate leaf springs. I originally wanted only a 2" lift but they can't do a 2" lift with springs because the front springs are curved the opposite direction and a 2" lift would make the springs in the front flat.
I also went with a single front Shock and put in the Bilstein 5100 shocks.
This changed the ride completely, I still tow my car trailer without any problems but have a much more comfortable ride. Off road the Suburban handles the bumps and rock without any issue.
I did change the pitman arm on the front and did longer brake lines but I also upgraded to Wilwood Calipers up front.
The change over to the progressive rate springs was great.
