Omix Heavy Duty Leaf Springs


NAXJA Forum User
Anybody have experience with the omix heavy duty leaf springs? I put on regular Dorman leaf springs last year and they are already getting saggy. I do occssional light towing with a flatbed trailer full of rafting gear, nothing crazy.

If you have used these, how much stiffer are they than oe leaf springs? Do they retain their lift very well over time or will they also get saggy within a few thousand miles? Thanks!
The Omix HD leaf springs are said to be similar to the Up-Country option factory leaf springs.

I have found that a stock XJ main leaf with the spring eyes cut off and installed into a stock leaf pack improves the load carry capacity and helps prevent sagging, without changing the ride quality.
