Sport max tow lift recommendations

[MrKnowitall]

Except Mopar/Jeep does not provide how much decrease in payload/towing you have because of the changed suspension. So there goes your truck abilities. I'd estimate because of the springs used you have Rubicon numbers: 1100lbs payload.

Chances are the lift springs are a higher rate, so it should carry just as much.

Mopar 2" lift is a much softer springs than the Max tow. The rear springs on a Max Tow are pretty stiff to accommodate the tow ratio. The best way to lift one to maintain tow rating is with spacer lifts. You will still lose some even with those.

Maybe a spacer lift and 33" until the warranty is out then. Either way the stock tires are garbage and need to replaced ASAP.

How do you know this?

On the max tow yes. But they are relatively light and help contribute to it’s tow rating. Falkens are quite heavy

Stock max tow tires are about 34 lb. You can get Falken AT3W in the same size and SL rating for 41.4 lb. In E rated, they weigh 51.4 lb. I opted for the 255-80-17 E rated Falkens which weigh 52.5 lb, still 10 lb. less than the Rubi AT3W's @62.8 lb. I wanted to minimize the impact on tow rating while substantially improving trail performance.

I considered doing the Mopar lift but my buddy at the shop compared the springs on mine to Mopar 2" lift springs and said that the rating was different, especially on the rear springs, where it matters. Towing capabilities is the reason I went spacer instead of spring lift. No matter what, adding larger tires and lifts will bring your tow rating down, adding a softer rated spring just going to bring it down that much more. I couldn't even begin to tell you how much though.

If you want a light 35, the BFGs I'm running in 315 70 17 are 62.4lbs a piece in E rating which is has the stiffer sidewalls. In C eating they are 63lbs. Actually height is right at 34 with 44psi in the tires. They ride great, and are great for off road use as well. Been running them for over 5yrs now.

I am sure I'll be happy with anything from 33-35" for a DD.

The tires absolutely reduce towing capacity. I would argue though that in the category these are in, the rear springs have little if any effect outside of maybe a payload reduction. Any travel trailer would not have enough tongue weight to where the rear spring rates would matter.

No real world experience other than what a 40yr off road guy told me about the Mopar springs compared to mine. Only reason I didn't install it and went with a Spacer lift, that and after I drove one that had the Mopar lift installed and felt how much softer the ride felt compared to mine. Both of these factors led me to do the spacer lift over the Mopar. I'm not sure how much towing you would lose, but I would imagine with softer springs in the rear your going to sag more than having the stiffer Max Tow Springs installed.

What spacers did you use? And what size?
Did you switch out the shocks ? Fox?

ReadyLift 2.5" SST lift kit and Rubicon Front take offs and Rubicon Take Off Fox Shocks. I'm riding on 37's now with 1.75" wheel spacers

3.5" skyjacker coil spring lift. It doesn't sag too much under a load and rides pretty good. Probably more than what you're looking for but just shows that you can do a spring lift and don't completely lose your "truck" abilities.

You definitely need a weight distribution hitch with what your towing there.
