Which 100 spring?

[Mxndrnks]

The 30 mm add around 1".

I was running the 860's from the Sleep medium kit with 30mm spacers. With a BOIR rear bumper, fridge and recovery gear, I was getting rubbing in the inner wheel well when in Moab. I recently went to 863's and the ride is stiffer. But it definitely ride better when loaded. I plan on putting in drawers which should balance everything perfectly.

The 860 and spacer combo rode and looked great until offload. They were just too soft with the New bumper.

I have 863's. They are stiff and tall. Even with a bunch of stuff in the truck they still don't flex that well.

I ran 863s in my old 1999 and thought they were perfect with a pretty good stock vehicle. I like a ever-so-slight stink-bug though. I never once had any flex issues with them, even unladen.

An OME 863 is about the stiffest spring available for a 100 rated for 3" of lift in the rear and 300-500lbs over stock setup. You shouldn't run these unless you have a heavier aftermarket rear bumper minimum.

Well, on my 2004 I have a rear Slee bumper and think 864s are now perfect for that. I don't think I come close to 3" lifted. I know for certain that loaded down for a trip and w/ 863s I'd be dragging ass like a cheap desert rat's pickup.

^^^ Same here...863's were inadequate once I filled the drawers and added the aux tank. 864's work great...until I drop the KK tongue on it...then it sags. I've been experimenting with nitro psi in the Radflos and that makes quite a difference (positive) when variable loads are applied to the rear of the rig. But not quite enough to fully compensate for the 350lb tongue weight of the KK. 3.0 shocks with a 1" shaft/piston might have been the extra lift for mine...
Ideally I don't want to put the air bags back in...but may have to for the trailer trips...

 

[Pskhaat]

Spresso, did you try the 868s? I used them when towing a large camper with my 80, worked very well and not higher than the 864s, just better weight.

 

[spressomon]

I haven't. Per Kurt's chart they're the same spring with the exception of the 868 having 1mm larger diameter wire. I spoke to Christo about his springs...hoping he had a coil with slightly larger wire diameter but shorter free height...but he doesn't. A couple buddies are using his progressive coil on the back of their 80's to very good results. But per Christo that spring would provide too much height for us...

FWIW, I'm selling my 868s as I'm no longer towing, but they did indeed work well:

Bump an old thread. I just bought some used OME 866's. Anyone running these and have feedback?

I had 865's with a stock bumper and loved them. I installed a Slee rear bumper w/ single swingout and lost about an inch of height and felt squirrely with a full load.

I switched to the 866's and thought they rode a lot like the 865s with the stock bumper. I've recently removed the swingout to regain easy access to the rear, and feel the ride is a bit rough onroad.

I have a hitchmount dirtbike carrier that I've used w the rear swingout attached, and it definitely sags the 866's...need airbags.

My $0.02....

 

[Mxndrnks]

Now you guys got me wondering if the 863's I just installed are going to be too soft once the drawers are built and filled...........

 

[petrotk40]

Pskhaat, I might be interested in your 863's

I'm getting a BIOR lo-pro bumper and am going to need to upgrade my springs. Will 863's be the ticket? Or should I go with the 866's? I'm 80% miles in town, no cargo.

After some searching, I think 866's might be the ticket. The 863's look too tall without 35's.

 

[Pskhaat]

Personally, I think the 863s are near perfect with a mild load. I ran the 863s without a rear carrier and just our stuff, it was the wife's DD and she had nay a complaint and liked the looks a lot. When I got the rear slee, I now run 864s....so just my opinion that 863s would be really good choice for most folks (probably less loaded than I) who run with a rear bumper.

PM me anytime, still got those brand-new 863s for sale

 

[petrotk40]

Do you have pics of your wife's truck on 863s? I'm not sure what 863s and 33s look like.

 

[Pskhaat]

I'm looking and though there should be SOME out there, I can't find them. However, here is a picture with a pretty average/minor load on a recent Utah trip. This is WITH the slee rear and they are 864s. Unladen and with rear carrier, you would likely sit like this:

 

[petrotk40]

Like a red x?

 

[bluecruiser]

I have a 4x4 labs bumper with tire carrier and maybe 120 lbs of drawers/equipment in the back. I run the 863's and have never seen another 100 sit as tall as mine in the back. It could be just the cut of the other bumpers, but I don't see you having any issue with 863's unless you are also considering aux tank...that is heavy...

 

[paflytyer]

I'm almost positive Romer runs 863's with 33's and a fully loaded rig. I've climbed in his truck, it's just right IMO. Although when I see his rig on the road, it looks tall, it just doesn't feel as tall when you stand next to it. Some photos of his rig are here.

I have been running the 866 springs for about three years. Moved from my 865's when I installed my Slee rear bumper. You will notice a difference in ride compared to the 865's. The rear will be stiffer but not a dramatic change. Ride height will remain the same in back.

Now after adding sliders and steel skid plates I'm thinking I need heavier springs. Got under the truck the other day and noticed that the 4 upper coils are all compressed and sitting on top of each other. Since the 866s are progressive springs, those are the softer coil section. It appears I'm riding on the heavier coils. Anyone else see this with these springs?

Not sure I want to move to the 863's as I'm not interested in cranking the front T-bars much higher. Slee has some of his own label heavier 2" inch lift springs that may work. Anyone running those?

I have been running those for a while and really like them a lot. Back when I was initially discussing my plans for my Cruiser (pretty much what my sig says now) those were the coils Christo recommended...I was already bouncing between the 866 and 863s. The only thing I have not done is do a run with the drawers fully loaded. I did have it loaded pretty heavily for the last Moab trip so I don't imagine there will be much of a difference.

 

[3rd Cruiser]

Bighead,
Except for the drawers our rigs seem to have the same amount of added weight. Both the Slee SOF2RH and 863 springs have a 300 to 500 Lb rating. I like the fact that Slees springs only lift 2 inches in the rear. Sounds like that should be the way I go too. What shocks are you running?

I'm running 866's on 34's without bumpers (yet). Ride is a little tight but not super stiff. I'd say BMW vs Buick rather than 1-ton vs Buick. My bet is that the BIOR will be just the ticket to smooth out the rear.

Where did you get your spacers?

Kind of a mouse trap but kicking around the idea of 1" spacer, 866s and airbags...

This way I get a 3" lift without the stiffness and when loaded I could pump the airbags..

I've added what I've needed to my 100 as new things are added or installed on my rig. My goal has been to retain the best ride possible and make necessary changes when more weight is added. For example I didn't replace my stock tbars until I added my aftermarket heavier front bumper. I've also been running OME 865's with 1" coil spacers to give me 3" of lift in the rear and help with clearance of my 315/75/16 BFG KM2's. The 865's have served me well with basically stock weight in the rear. I have OME 863's in the garage waiting to be installed at the same time I add a new rear bumper. The Slee website spring page is a good reference for anyone trying to determine what will work best with their setup and the amount of weight over stock you plan on running.
