Looking for Coil Springs That Allow the Most Travel (LJ Build)

[agboys02]

Building a long-travel LJ on 1-ton axles (front Currie 60, rear HP60). I’m keeping coil springs (not coilovers for now) and want to squeeze out as much travel as possible.
What coil springs give the most up/down travel without coil bind and still return to ride height properly?


Some context:

• 40s, LS swap
• Rear triangulated 4-link, front 3-link
• roughly 4” lift target
• Willing to raise coil buckets and already planning to adjust shock placement
• Front and Rear highlines

I’m not afraid to run long coils if it nets more usable travel. Just don’t want some flexy piece of spaghetti that rides like crap.
Ive looked into metalcloak and currie but haven't found clear numbers on travel

Currie/RockJock 4" is the go to coil spring for 11" front, 12" rear shocks. Look in the resources section for my big shock and spring spreadsheet.

Regardless of what you do, the springs have nothing to do with how noodlely crap your rig drives. That is the fault of your garbage shocks.

tough choice. My front gets 12-13 inches of usable travel, and 14- 15 inches in the rear. Really don't want to go to coilovers due to maintenance and $$$$

You're on 40s with an LS swap and now you're worried about things getting expensive?

If you want to use that travel, then you are looking at coilovers. Or you are building for springs that fall out of place at full shock extension.

I get that but i plan to go cross country on this rig. I bought my lj for 9,000. sold all parts I wasn't going to use which got me 500. for the swap I got lucky and only spent another 9000 (mostly through FB market place and self labor) so I'm less than 20,000 in. Not including my suspension as I'm not finished but I'm 2500 in including the skid, and control arms. Just need springs and shocks. Truth be told I have the funds I just don't want coilovers. Im sure they are better but... i just don't like them

I though about using spring retainers that catch the coil at full droop and mount my bump stop outside but that lowkey sounds like more work might just conclude to doing coilovers next year. Also has any one ran swaylocs front and rear. i plan on doing it

I put a lot of effort into my front and rear 12s not being a complete hack job, so I can't help you there.

I was unaware that ORO offered a rear SwayLoc. I have one on the front with a factory rear sway bar. The only change I plan to do is a rear AntiRock because it is stiffer with longer arms compared to factory.

They dont but ima make it work. I will likey use the jk one and fab some adapting plates

You’re in coilover world unless you want to severely limit your entire build.

A rear SwayLoc is the solution to a problem that I do not understand. And you don't want to build a proper suspension elsewhere.

I spoke with Steve at ORO about this, he said it's pretty impressive how well a rear swayloc works on a build. He was building a V8 TJ with one last time I was over there.

okay, ig ill run coilovers. my plan is to try out SDI's e-click system cus it allows for onboard tuning. We'll see how the Jeep does with body roll on the freeway and sharp turns before adding a rear sway lock. Anyone got recommendations for coilovers?
