Rubi vs sport s max tow front springs

[RufusMalloy]

Hi, I'm am fairly new here and I know this has probably been beat to death but I can't find any definitive info.

I will be installing an arb classic front bumper and winch on my sport s max tow jt. I know this will make my front springs will compress more due to the weight. I would be interested in gaining this difference back using rubicon front springs instead of spacers. I only want to swap the springs out if the spring rate on the rubicon are close to the sport s max tow or higher. I also know that the rubicon front springs are different for models with steel bumpers or plastic. (Also I understand that diesels are different as well). I have not been able to find any definitive info on spring rate between models to do a side by side comparison. I just don't want to trade the 3/4 to 1 inch gain for softer springs up front. I should also note that I have access to both of the gasoline rubicon front springs.

Thank you all in advance for any help

It might not even drop at all if the difference in weight isnt much.

My front bumper is currently plastic and I think the combined weight of the bumper and winch is 275lbs. Not sure what the stock plastic assembly comes in at but I'm guessing it's 100 or less. When I sit on the bumper the front drops so I know it will drop some.

What did you end up doing here? How big of drop did you see?

currently looking at a bumper/winch combo in the 180lb range also on a max tow. Thank you

I dropped 9/16. Used rubi front springs from one with a steel bumper. Kept the max tow shocks. Still lost an 1/8 all said and done.
