rough riding YJ

I am rebuilding a 1988 YJ. I have replaced the entire suspension with new springs, shocks, etc. HOWEVER, it seems you can feel every pebble you hit on the road! How can I make this a more comfortable "street" ride yet let me do some light "mudding". I am not into rock-climbing!

Honestly, it's an old leaf-spring Jeep based upon a 70-year old design. Maybe softer seats or big tires with a street tread will help, but it is what it is.

If they are still on, you can pull the Track bars off, it will help a bunch. Particularly in the rear end.

I don't want to get into the whole "To Track bar or Not To Track Bar" debate again, but even the proponents of leaving them on can't argue that it does help smooth out the ride.
If you choose to say "plz" because it is shorter than "please" I choose to say "no" because it is shorter than "yes".

Recheck the torque reading on your shackle bolts.....most folks consider the factory torque settings to be too high. 45ft/lbs seems to be sweet spot.

Some aftermarket springs ride much stiffer than stock....not much you can do about that.

Run lower air pressure than max in your tires (tho it will hurt milage a bit).

Ditch the track bars, as stated above.

what shocks and springs are you running.

Ax on the shackles 45ft/lbs is a good place to start.

Experiment with the tire pressures. You don't have to run the max recommended which is what most places air you up to. My 88 on a RC lift runs at 30 lbs and no trac bars. More comfortable than 35 psi. Loosen up your shackles and cycle the suspension find a curb or a big rock and get them to flex. Retorque on the ground at 45 ft/lbs. I found the stock shackles just didn't seem to flex so I bought some booms and after install it was a real noticeable difference. On the trail I get down as low as 15 usually 20 psi to save my sidewalls or a belt separrating. It is a matter of experimentation on your Jeep and your lift to get the comfort.

Thanks a lot! changing the torque on the shackles helped a lot. I tried taking off the Track Bars but put them back on as I didn't feel comfortable with the ride. Like someone said: IT'S A JEEP!!!!!!!!!!!!!! and I love it!

Nitro shocks or heavy duty shocks can cause a hard ride too. Some of the lift kits come with shocks that are too stiff for a 2900 lb. Wrangler. I found reg. hydraulic shocks gave mine a much better ride. I also removed my front track bar permanently, I only remove the rear track bar when off roading, due to the roads where I live are very curvy. So with the front sway bar and rear track bar installed , it handles much better on the roads. I also never run more than 28-30 psi tire pressure. 15-20 lbs. when off roading

Just keep in mind that a Jeep Wrangler does not weigh much, just 2950lbs. stock, so it requires less tire pressure, spring capacity, shock pressure, etc. than say a 5000# plus truck.

Although I personally run my 3/8ths thick, custom made, greasable shackles torqued at 35-40 lbs., I personally do not see where shackle bolt torque would effect ride that much, due to the fact the pin rotates inside the bushing and the Shackle Bolt torque is applied against the outer ends of the bushing pin, not the bushing or the leaf spring. Now, stock shackles are rounded, concave, and shaped to the stock bushing, so I could see that maybe making a difference with torque settings.

Large tires will Carry more weight [a heaver load] at the same PSI than a small tire, so you can run them at a lower PSI to do the same job, making them ride a lot better.
