Extremely rough suspension

Hi,
I was hoping for some advise. I have a 85 cj7 seems to be lifted 3-4” (I got it this way). The ride is extremely rough, I have aftermarket corbeau seat which are very padded and comfortable. And after a 5-10 minute ride my back is absolutely killing me from the rough ride and bumps. I brought it to my mechanic and he removed 1 leaf and it helped with the roughness a little bit. Also deflated the tires slightly. Is there a new suspension kit I can order or that anyone recommends for a “comfortable” ride?
Thanks!

Always heard the Old Man Emu YJ conversion is the way to go. My plan for my 81 down the road is their 2.5 lift conversion.

check the tightness of the bolts on the shackles and what kind of shocks do you have? Both can make for a harsh ride on a light weight vehicle like your Jeep.

As already suggested, shackle torque and shackle angle, shocks, and tire design / tire pressure can have great effect upon the pavement ride.

Whatcha got for each ?


My CJ-7 BDS lift and BDS shocks ride great with the 31x10.5 tires at 28 psi.

A friend of mine had the same problem with his cj-7. We use to take turns driving to work in it one week on and one week off. He bought it from a mechanic that did all sorts of things to it. 2 weeks a month we had stiff necks. He tried high back buckets that helped a little shocks ,tires leaf springs nothing helped. It was built for off road with a 351 ford motor. Finally he found 2 air cushion seats like in a tractor trailer. It made it drivable on the road. the seats worked well. I'm not sure what he got then out of.

Thanks everyone for the responses. I’ve looked into the old man emu YJ conversion. I think that might be my choice for now. Does anyone have a part list they have used? Parts they really liked? Thanks!

Heres a kit from Rocky-road outfitters, i highly recommend this company. while they say its a 3-3.5in lift i got my in march 2020 and when i measure it was a total of 2.75in lift now its sitting about 2.5in. The jeep rides pretty smooth handles great with 33s and 31s, just make sure to get the correct castor wedges.

Side note i also installed the HD rear shackle hangers and long travel shock mounts up front, Ive broken a spring plate that they supplied in the kit, contacted the company and the only question asked was which side and front or back.

Awesome, thanks everyone! I’m going to go with the emu conversion. One more question. What shocks do I buy? CJ or YJ shocks?

Your fix may be easier and cheaper than you think.
Do yourself a favor, pull the shocks and take it for a spin. Most lift kits run waaaaaay to stiff shocks.

True, that’s a good thought. I’ll try that. And I run 33x10.5. Have 1” body spacer

Absolutely this!! That was great advice!!
Now I’m on to the OME YJ Sping conversion.

**Word of warning**
The springs are backordered big time!!

Don't let anyone talk you into buying high pressure gas shocks. I have Doeschtech 3000 series hydraulics and they ride nice.
