Soooo I need some help
I noticed my XJ is starting to sag more in the rear now, one day i loaded some stuff and when i hit a bump the diff hit the floorboard and cut the fuel pump wires. Ive replaced the leaf springs about 4 years and maybe only connected a trailer 3 times to it and the leaf springs have no arc to them anymore.
So my question is what would be the better choice HD leaf springs or an air bag suspension?
Would like to hear ya thought and personal experiences with either one or both, also any specific brand ya recommend?

thanks!

This depends on a couple of factors. Is the Jeep staying stock height, or are you lifted? And do you plan on pulling more trailers/weight in the future or on the regular? If staying stock height, a good set of HD springs coupled with some air shocks or air lift bags will help. If lifted, there really isn't a lot for options other than adding an overload spring.

I plan on keeping it stock height wanna keep it as my daily, as for towing it wouldnt be an everyday thing but I every now and then i will be pulling a trailer nothing big but still.
Any specific brand name for the air lift bags?

Correct me if I'm wrong, but you might want to look at your rear bump stops to prevent future diff contact.

Pretty much personal preference and what you can afford as they are all made the same now. But me, I'd look at a company called Air-Lift first.

This is always a must. And I would recommend looking at the Daystar brand bumpstops.
