View Full Version : Higher spring rate coils

So I have re 3.5 lift coils up front and dodge van 5leaf packs out back. The rear has a great ride and flexes great when in extremes. I find the the front flexes quite a bit easier though. So I'm looking to get the front up to 4.5 inches. I already have the back worked out with shackle and relocation. I need stiffer front coil to make the rear work more and give more balance to the overall performance in the rocks. From my calculations the 3.5 re springs are around 200#. My research is finding that a lot of guys like running coils that are ~250#. I'm looking to order a set of coils this week and need to find some quick. Also wondering if it would be wise to try and find some 5.5 or 6" springs and cut them down to get a higher spring rate.

Your RE 3.5" springs are 240#, the taller RE springs are softer.

Thanks for that. I was looking for two hours last night trying to find some actual numbers.

So any ideas on where to find higher rated 4.5 springs? Or opinions on getting a taller spring and cutting to the height desired?

Before answering your question I have one of my own.

What shocks are you currently running on your rig? The issue you're having may be related to having the wrong shocks.

Up front I have some cheap and really stiff i might add white rockets. out back I have the cross enterprises shock hoop and basic procomp whites. The shocks are set at the outmost position on the hoop. The back end is really soft on the street.

When I go over speed bumps the front doesnt even cycle. The rear gets about one good cycle.


I will say that as soon as i can get this figured out I will be ordering new shocks from serious


In its current state. I can only stuff the rear tire if im going up hill and more of the vehicle weight is shifted back. On level gound it doesn't seem to work as much. because the front is softer. Its not a huge difference and I could probably live with it but I'm looking to get a bit more lift and cant find any 4.5" springs with a higher rate. I used to have spacers but I'm trying to get away from that.

My $.02

JKS ACOS and keep the 3.5" coils if you want to maintain the higher coil rate.

Better shocks too. Bilstein or RE monotube FTW.

i would look to soften the ride in the rear rather than stiffen the front. What is the spring rate on the rear leafs?

I would prefer not to soften the rear. As right now it is pretty soft and I haul equipment and tow periodically.

I have a set of 7.5" lift springs I'm thinking of cutting down so maybe someone can check my math a bit.

Here are the specs
Coil wire size .685"
Outside coil diam 5.45
Active coils 14
free height 23

My calculation put it at 204#

If I cut 2 coils off it should put it should end up being 238# and be about 3" shorter. That would land me about 4.5" and a higher spring rate.

Love my deaver coils

get your suspension where you want it, then get some decent shocks

This is indeed the plan

Does anybody have any input on this. I'll probably end up being a guinee pig. I'm ok with that though.
