Fox stage 1 suspension support OME rear leaf kit

[Krudo]

Hi all new to the forums here.
I was pretty disappointed with the fx4 performance - felt too bouncy and floaty for my liking. So opted for the Fox stage 1 performance kit which I’ve been much happier with.

I use a camper on the back quite often weighs around 1100 lbs. Truck handles it well but in anticipation of getting it I had ordered the OME 2.2” leaf kit. I haven’t installed them yet, as I read something that concerned me that the travel of the rear fox shocks could max out or even exceed if I add that much lift in the rear.

Hoping the great minds here with far more experience with this kind of thing can help me out. Is this a bad idea for when the truck is unloaded? I’m assuming it’d be fine when loaded down just potentially a problem if unloaded and hitting maximum suspension travel in the rear?



Thank you for your time!

If I'm not mistaken the leaf spings you chose are meant for a constant load of 660 lbs in the rear at normal height. Without a load it could be a little higher. I myself have the Old Man EMU basic lift and the rear springs I have only lifted 1.6 inches. They handle load of trailers just fine but the main thing is how.much toung weight.

From your comment above I certainly hope you are saying the trailer weighs around 1100 lbs and not the toung weight as that would indicate a trailer the is way to heavy for the Ranger. If the trailer only weights 1100 lbs chances are you dont even have to worry.

Here is a picture of my truck with 5500 lbs of weight being towed.

hey frenchy thanks for the reply. I actually think your comment was the one I originally saw that spooked me, just found it again: https://www.ranger5g.com/forum/threads/thinking-of-adding-ome-rear-suspension.11488/post-219615

the camper is not a trailer but is in the bed of the truck

I will simply say that the Old Man EMU springs you have should be of since it is an in bed camper you have. With that said if you have the trick unloaded it will be a 50/50 chance of weither or not it will be an issue. The reason I say this is because when Fox first released thier suspension the rear shocks were rated for 1 inch of lift ar best. To.my understanding that was changed but who can say if it was supposed to be up to 2 inches or not.

I good indicator would be to compare the compressed and extended lengths of the OME shock model they recommend for their springs to your fox shocks.

 

[Metalshift]

The shocks will be fine. The concern is with compressed length. To run a longer shock you need to use longer bumpstops or lift blocks to prevent crushing the shock. The way the leaf springs are designed I doubt the shocks will be the limiting factor.

Yeah with the Old Man EMU springs he wont have to worry about the bump stops as the rear leafs get changed from parabolic to multi leaf. If I remember correctly for the standard leaf pack its a 4 leaf design and the one he has might he a 5 leaf design. With that said he wont have an issue on compression. His issue is going to be possible overextention.

Yep so heard back from fox sales:

Yes the shock will most like be too short. If you look at the specs online, we only make an application on the 2.0 for 0-1.5” lift.

For daily driving we would most likely not run into any issues, however when off roading, the shock will top out and be fully extend ¾ of an inch prior to the suspension being full extended. Continued use of the shock being the limiter on droop could damage the internals.

Kind of disappointing considering stage 3 recommended this combination of suspension parts to me.

Curious if anyone has reccs for what my options are here. I’ve installed timbrens and they are touching the frame once my camper is in the bed now with the fox 2.0. Would be great to get a bit more clearance in the rear.

Due to tue amount of load from the camper there really isnt a leaf replacement optuon that will help with the Fox Suspension. The basic Old Man EMU springs will take roughly 780 lbs before the truck is level. Mind you they lift the rear 1.6 inches. The mid level springs do have a little bit more but are designed for a constant load of 660 lbs while maintaining lift and that is what you were looking to get originally. My suggestion is simple. Either keep what you have and add air bags(not the best option) or simply swap to Old Man EMU and sell the Fox kit(I know you may not want to but it may be the better option).

alright, was guessing replacing with total ome solution would be the sensible route. What about just putting in the ome rear shocks https://www.stage3motorsports.com/6...u-nitrocharger-sport-rear-shock-standard.html but keeping the front fox coil overs?

 

[Frenchy]

You could but I dont recommend it for a reason. With the front and rear not being matched with the shocks(both brand and type) there can be some conflicts with the ride and handling. Enough to cause safety issues? Hard to say but still possible. Like tires you want to keep the same on all four or they will tend to fight each other. Make sense?

 

[Frenchy]

While I'm thinking about it there are the APG deaver spring to consider. Mide you they cost twice as much compared to Old Man EMU but I have seen reports on here from other members running them with Fox and Icon and liking the results.

 

[Mote]

Some information to consider:

OME 60156 rear shock (used with OME light and medium leafs) compressed length 15.16" Extended 24.6"

Fox 2.0 rear compressed length 15.49" extended 25.03"

if 24.6" fully extended works then 25.03" should also?....

Kind of curious where you got the information for the shock lengths. This is the first time I've seen the specifications on them

very interested in source for this as fox rep said above it could be an issue.

here’s a response from APG regarding their Deaver leaf springs paired with the fox 2.0 for any interested:

The shocks are usually the limiting factor on suspension systems, unless you are jumping your truck, I wouldn’t worry about fully extending them. Both our springs are designed to maximize travel and not be the droop limiter

interesting take as it’s a bit different from FOX’s above in that he’s saying shocks are expected to be the droop limiter. Could always chance it I suppose with the fox and replace them if/when they fail
