Help me out here: Rubi shocks on max tow sport s

[Backwoodsraider]

I've read, non stop, and can't find a specific answer.

Max tow sport s, if i put rubi shocks on it, how will the ride be?

Rubi springs are longer in front, right? how will the shorter spring affect the life span of the longer rubi shock?

Rubi sprigs are shorter (???) in rear, or just softer? how will that affect the shock life?

Would love input from people who have actually done this

Thanks in advance

Wonder if Max Tow springs would work with Rubi fox shocks to keep the payload numbers up; not worried about the lift?

If you change the suspension/tires on a vehicle you change the geometry and thus things like towing and payload will be affected. I know for a fact by looking at the rear spring part numbers that a Max Tow Sport S has beefier springs.

The topic has been covered in at least three threads already, not including this one

You might be able to get better payload from a Rubicon if you change out the springs, but it is uncertain and unlikely. The Rubicon already has good springs. It’s towing capacity is lower from the Max Tow because it is heavier. The payload is less because it has a performance oriented suspension. But because you have a taller suspension on the Rubicon you cant just change out springs, you would need to replace all the components. How this will affect your rated payload may be as simple as increasing it a couple hundred pounds, or not at all. The best folks to confirm for warranty/liability purposes would be to email FCA

Rubicon sits higher. I can't swear to it but because of that I suppose it's possible the Rubicon shocks are a bit longer - maybe.
Why would the life span of the shock be impacted? It may be traveling LESS distance so should last just as long if not longer than on a Rubicon crawling over rocks and extending the suspension to the max and compressing it to the max.
Rubicon springs are not shorter - why would they be - it sits a tad higher.
Softer or harsher springs have nothing to do with shock life. The shock is a DAMPENER only- it dampens spring oscillations. If the springs are really soft I suppose the shock could be moved more and wear a bit faster but that's really getting out there - really reaching.
Shocks dampen the oscillations of the suspension. Stiffer shocks make it ride stiffer, or harsher, as they resist being compressed and extended while other shocks for comfort move more easily in either direction.
Drag race front shocks are a good example of how a shock can act for you - they are often 90/10 shocks - they extend outward really easily, but compress back far more slowly than others. Most shocks are closer to 60/40 or 50/50 extension vs. compression.
But springs should have little to no impact on shock life. And shocks will have no impact on payload or towing other than how the thing rides when loaded. They don't change capacity at all.

The payload numbers are not only springs. They are axles, ratios and other things. Swapping springs won't change your payload or towing ability. Might keep the rear from sagging, but won't boost your numbers.
And shocks have totally zero to do with payload and towing ability. You could put any shock on there you want and it won't touch the payload numbers one bit.
If the drivetrain - the axles, the bearings, axle tubes, axle sizes, that sort of thing aren't rated for it, springs won't matter much.
Max tow springs wouldn't lift a Rubicon - at least my understanding is the Rubicon is about an inch higher from the factory.

The shocks are the same length. The Rubi front has a higher spring rate giving it 3/4 to 1in difference over the sport height. This difference is negligible and irrelevant where the shocks are concerned. Swap away. If you can get the front springs from the Rubi too. It'll give you a slight level but keep your rear springs from the max.

 

[ShadowsPapa]

The shocks are the same length.

Not surprised as they likely would use the same LENGTH shocks, they just won't travel as far on the other levels of JT

So if I wanted to take a bit of the rake out of my Overland, Rubicon springs on the front?

If shocks have nothing to do with it then why did the engineers at Jeep give the Max Tow package a different rear spring? Per FCA changing out anything in the suspension will decrease towing.

ETA: if I am mistaken or misheard what Jeep told me, then I am ok with that. Anything that lets me upgrade my JT and keep the payload/towing capacities will be a win and I will be happy to be wrong

Nvm I meant springs and misread things.

Sorry, you confused me there - the shocks don't impact payload, springs do -
but you asked "if the shocks have nothing to do with it ...... why did the engineers at Jeep.....max tow.... different rear springs"
Max tow does have different springs.

You can change shocks and not impact payload, but the springs that's a different matter.
Or did I word my response poorly??

Shocks dampen spring oscillations - without them the vehicle would bounce like a rubber ball as the springs release energy.
Shocks don't support weight at all - because of that they won't impact how much stuff you can stack in the truck bed.
You could change shocks and not springs, springs and not shocks,
but changing the springs would, or at least could change payload rating. Changing shocks would not since they don't support weight.

Yep. 3/4 to an 1in taller

No, no, you’re fine. It was my mistake. I got confused by reading too quicku. Hence my edit thinking I was surely mistaken somewhere

THANKS! Good info as I AM thinking of taking just a bit of the rake out........ and eventually different tires but then only thinking 33s - something better for snow and crud.

Whew! I DO have to be careful as I have a condition where I get to typing and my thoughts and fingers don't line up and words can be transposed or left out. (and I stopped the drugs for it)

Look for a 255 80 17. Tall and skinny does better in snow

Concerned about skinny in the slush and ruts - tends to be pulled around in my experiences.
I don't mind the deep fresh snow but the tracks, it gets packed, then the slush - hit that and it can jerk your vehicle right off the side.
Was looking into more of the Falkens - as someone here said "with the mountain/snowflake" symbol.
Overland - 18" wheels.

But have never done a side-by-side as far as "tall and skinny" vs the others.
