Can you clarify - did you use both the 10" and 12" springs?

Yes its a dual rate coilover.

Yes, 10" upper and 12" lower. These are dual rate shocks as mentioned above. The problem is, the upper is too short to allow the shock to compress enough before hitting the dual rate stop and transitioning to the bottom 300 lb coil, and if we move the dual rate stop up any higher, it blocks the tender coil from extending properly at full droop. The combined overall rate of 120 lbs per inch works great however.

Simple solution will be to trim an inch or so off of the dual rate slider so it contacts the dual rate stop later in the shock stroke.

I forget what I figured out for the rear rate, I think it was 125 over 175, 10" and 12" again respectively.

Normally both springs would be the same length as the shock travel (in this case 12") and would be preloaded at full extension, but when you short stroke the shocks (more downtravel than up travel) like this, rates get tricky because the overall rate would need to be way too soft to obtain preload, and a tender coil is required to keep the springs from being slack at full extension.

I've been busy tearing it apart for paint all weekend and installed my atlas. The atlas install was straight forward removed the 231 and slapped up the atlas. I had to grind a hair off the trans mount bracket to clear the tcase but nothing major. It clears the tub/bellypan like a glove with 1/2"-3/4" of clearance all around.


I also started chopping the tub to move the flare back to hide the 3" stretch. There's alot left todo this week mainly the tank issue, driveshafts, brakes and torque everything down.

I got both my front driveshaft shortened and lengthed the rear shaft this weekend. My rear shaft is a 1350cv out of a 90's dodge 2500 I cut it down to about 25" running length.

I also threw the stock tank in the back of the jeep with a couple ratchet straps for now. Just have to extend the fuel pump wiring and it'll run again.
The brakes are almost done and I've got a couple ideas for the exhaust. I changed springs on my coilovers to 170/250 and it looks to work alot better.

Its a driver!!

I drove it for the first real time this weekend 3 hours to RC. The suspension and atlas worked amazing. The coilovers really soak up the bumps. The waggy 44 didnt fair so well though. I broke both front shafts and ujoints making for as whopping 20 minutes of wheeling. Heres the few pictures we got

In the parking lot getting ready to FAIL

ON the ramp checking clearances

Nope no chromos. Might get some though.

After his broke we jumped in my buggy and went back out. Not long afterwards, I broke an axle joint in my 60 that took out a chromo stub shaft, and my last stock inner. Today was a bad day for axle shafts

Hi Chris, Do you no longer have the YJ?

Bummer about the shafts & joints. Good to hear you got out okay & limped home.

Joe I still have the blue YJ buggy you saw when I was out at hammers this year. It's working great but I might sell it next year and build something new.

Yea just stock shafts and joints that broke. Some ten factory shafts and excaliber joints should be here this week to replace the mess in my front axle. I'm going to pick up a set of stock shafts as spares if I can ever find some around here. My frontend should be set for 35's.

I got the new joints/shafts in and all buttoned up. So we took it today to a local friends property and beat the balls off it. Everything held together fine without any mechanical failures. I have to round up some pictures and videos from everyone. Here's the one picture that I have where I launched up a hill caught air and landed on a stump with my tierod. Chainsawed the stump and backed off it
