Rear end sagging

[Pescatoral Pursuit]

Same, synergy was spooled up to talk about its product, as was Rustys.... evo wanted no part of it....

Got ahold of someone at Evo.
They wouldn't give specs but did say this:

They only make 2 springs: Plush and HD.
They market the HD also as their diesel spring.
Their Plush is comparable to Rubicon Springs.
Their rear HD/ diesel springs ARE NOT a heavier rate. He said they have issues with heavy rate rear springs springing from their perches, so their rear HD/ diesel springs are ½" longer but same spring rate as their "Plush."
(Anyone else think of a 1970s sofa when they hear that word?)

Have you talked to Clayton yet?

Their triple rate rear springs might be what you're looking for.

Unfortunatly Clayton limits at 3.5, I'm already 4"+ with the Rustys so a 3.5 would induce an increased sag....

Clayton springs run tall.

Wouldn't surprise me if 3.5" Clayton springs are taller than 4" Rusty's springs.

I'll call them and ask for an unsprung height.... thanks

I've had good experience with Rusty’s that go's back to the lift kit on my XJ. I've been by Rusty’s place a few times. The lift kit I got for my JT is from them. I was there getting a set of shocks, the day after my lift kit shipped out. I had a few calls with Rusty’s when I was dialing in my XJ's suspension year ago. Customer service was always a high priority with them, in my experience.

I really do love my Rustys lift, I just overtaxed the rear springs with the cap and gear

I'd also talk to them about your specific setup. Maybe they have another customer who paired their rear springs with Rusty's 4" front springs.

I'll mention it, but even loaded the front springs have no issue..... the lift it self has been spectacular, zero complains on or off road, best buy I've made... but rears just really aren't overlanding springs if you load up....

Well that's good "or bad to hear" in my case. So I my be needing to look into different rear springs to, if I do I'll probably be added spacers in rear as stop gap.

What do you think that's going to do besides tell you what the unsprung height of Clayton springs are?

You may find this email reply from a certain company which sells gladiator coil springs, answering a request for their spring rates and unsprung spring lengths, helpful:

"Our Gladiator springs are designed to level the Jeep. So the 4.5" rear springs when installed wont give you the full 4.5" height. I'll list the specs bellow for both our 3.5" spring and 4.5" spring.

Unloaded and loaded length for 3.5"
24.0" and 14.75"

Unloaded and Loaded for 4.5"
24.0 and 15.75

Our springs use a progressive triple-rate with spring rates of 99.6lbs/175lbs/360lbs for the 4.5" springs
and for the 3.5" 85lbs/180lbs/360lbs."

Need some advice....

I have a 23 JTRD with a RUSTYS 4" lift and and a steel shell, it sits fairly level empty but sags when I start adding gear, it had a nice (required) rake before the addition of the shell and I need it back so I'm more level with gear and not doing the (fugly) Carolina squat....

What is a good solution?

Does it sag like that with only the canopy? How much does the canopy weigh?

With Clayton you would actually get about 9" of lift from a 3.5" spring. With about 700 pounds of weight it might sag 1/64 of an inch and it will ride like a log wagon, or a Toyota...trust me, I learned this the hard way
