Need taller springs for my k30 dually
My k30s springs are sagging terribly and i need to source some replacements can i use a 4 inch lift spring spring from a k10? I only want it to go back up to stock heigh maybe plus an inch ive been looking for a used set of cucv springs since there usually low mileage i figure they wouldent be as beat as mine maybe add a zero rate to it but cant source any but cane across a set of 4 inch front and rear lift springs for a k10 pretty cheap id ony use the front but i was wondering if they would even fit under a one ton or hold the weight? Any suggestions

Re: Need taller springs for my k30 dually
I think the fronts will fit as I believe all the fronts are the same length. The rears are likely different (k10 used 52" springs, the K20/30 used a 56" spring in the rear). They wouldn't have the same load capacity as your K30 original springs.
I recently bought springs online from one of the spring dealers (mine was Michigan Truck Spring). I would suggest looking at some websites for replacement springs, delivery was pretty quick - less than a week from when I ordered. |

Re: Need taller springs for my k30 dually
I fit 37s on my 4 inch springs. I dont think thats what youre looking for. 2.5" might be more what you have in mind.
73-87/91 square body trucks all share the same front springs. 1/2 ton rears are 52" long where 3/4 ton and 1 ton are 56" with varying capacities. If the lift kit you found is blocks in the rear then they will fit your k30. Just ubolts are the only change.

These are replacement 4-leaf packs for the front of a K30.

Re: Need taller springs for my k30 dually
Thanks for that i think ill just order a set of those and if its a little to low add a zero rate i dont want it lifted just more level the rear springs were replaced by the p.o and the front are sagged so its super raked and i hate it. Plus the front bump stops are only 3/4-1" from hitting there so sagged
