Nice stuff man. Can I ask, are you coilover tabs on the top of the axle tube? And what are you running for uptravel/down travel? Total lift height? A guy local here runs 14" kings with tribe towers tucked to the bottom of the engine bay and axle tabs behind the tube. 3" of up travel, plenty of total flex on 37's.


It does load the bushings constantly, but seems to work alright so far.

I've also setup custom brackets for a friend for 14" travel shocks on a coil sprung suspension.


I'm curious why you chose to run 14's into the engine bay. I would assume to mount them to the top of the tube but.....

 

Those look like ford shock towers

 

That they are... F250 towers trimmed to shape and welded to the frame and coil perch.

Sorry for the mild hijack OP, just fitting 14's in is a mild art form in a JKunless you start moving things around in the engine bay.

 

My shock tabs are on top of the tube. To be honest,, went with 14's because they are 2" more bad ass than 12's. As stated before,, 12's would have probably worked for my purpose. Sorry I dont have a bunch of numbers to post, I never really measured the lift. My guess is I'm sitting at about 5". I'm currently working with Rebel Off Road trying to dial in the shocks. They were WAY OFF from King. I have gone down 2 spring rates from the 300# lowers the shocks came with. As a result of the softer springs my front end is dropping a little, which is fine with me because it was too high before. Not totally dialed in yet,, but as it sits right now I have 4 1/2" of up travel. The towers are 19" high from the top of the frame rail.

 

Very clean

 

I wasn't talking about more flex. I was saying the coil over flex will kill a non Johnny joint quickly.

 

Don't overthink this. Look at my build specs. I had no cutting into the body with my setup and I will put my setup against anything else with 37 s for capability.

 

I run Johnny Joints as well, but they're not the only joint that can handle the travel. A duroflex has so far proved itself to work just as well as the Johnny Joint so far in it's limited time available, and it is actually proven to be more street friendly in terms of NVH. Heims, Krawler joints, Ballistic Joints.... all can handle high travel as well.

It should be overthought. Look at big dr's posts, in particular about his coilover setup. He's on his second revision to get it right for his rig. Every rig is different.

 

This setup looks sweet. The crossover bar reminds me of a high horsepower racecar.

From a suspension design standpoint, do you want the shock at a 90 degree in front/back and left/right or is it better to have a slight angle in either of the directions? From one of your pictures it looks like there is a very slight angle from the top being a little more inboard than the bottom. Is this to help it fit or for performance gains?

 

Slightly angle out at the bottom helps a little with lateral stability. Slightly angled toward the center of the jeep at the top helps utilize more travel through the arc of the arms.
