OME J Spring with 33" MTR's?? Anyone?

[Boston Mangler]

Gotcha, i am no where near that now or dont see myself at that point.

Example, we are leaving for a trip to baja this friday AM. my current setup is

rig = stock

gear = 2 tents, 2 ice chests filled with beer and food, camp chairs, , wood, 75lbs of tools, 5 people, all their "stuff" they bring, etc... that is going to be the main duty of my rig, trucking 4 or 5 folks camping, snowboarding, wheeling, etc....

probably wont do much or any towing

You'd be fine with the std. OME (850/863) or J springs weight wise. Your truck will have a slight rake (bug butt) stance. Many people solve this by using the slightly taller J springs only in the front, giving the truck a more level look. If you put J springs in the back, you'll be back to the rake problem, which is where spacers are used for the front springs, again bringing the truck to level.

I went with a little bit different set up. I did the OME heavies along with the caster correction bushings, and 2 OME trim packers per spring. I also added Slee SS brake lines, and 4.88's to help move the 315's--I ended up going with bfg M/T's as the the MTR's are on back order. It is a great set up I also have the arb up front.....

OK,

Lets do the math...............

863 = 50mm lift with 200 kg static load over stock.

863J = 75mm lift with 200 kg static load over stock.

864 = 40mm lift over stock with 400kg static load over stock. (actual observed lift on my vehicle when I switched to 864's is as follows):
The 864's lifted my vehicle an additional 32mm on top of the measured ride height with 863's when I installed them. It took 5,640 rounds of .30 caliber M2 ball in cans (420 lbs or about 200 kg) to drop the rear of the vehicle to the same height it was before the swap.

So, I postulate that the 864 "lifts" about the same as the 863J would in the case of an "unloded" vehicle but the 864 would support twice the additional weight at any given load vs lift with any given additional load. So, for example, 200 lbs additional load on top of this would drop 864's 1/2 as much as it would 863J's.

Gotcha

Thanks guys.

Seems standard J's might be right up my alley.

If i ran 864's and didnt have much weight in the truck, it would ride rather stiff, no?

That is an understatement.

I will expand:

When I first played with 864's I had Downey springs and stock shocks. At that time I had sliders and a stock rear bumper with an alloy wheel spare. When I was loaded I drug arse big time so I aquired 864's from a good friend. I installed them at work and had a helluva time compressing the rear axle far enough to be able to reconnect the shocks to the axle. To the extent that I had to chain the rear of the vehicle to the hoist to prevent lifting it clear of the hoist arms..

When I lowered the vehicle to the ground the rear suspension DID NOT compress enough to get the rear shocks off of full extention. It took two VERY LARGE fellows (close to 600lbs combined) seated on the tail gate to get the rear suspension to drop.

YIKES!!!

Thanks for all of your input!

I think J's all around would suit me just fine!

Are there any clearance issues with them and MTR's if i address the panhard rod issue?

Thanks

 

[Trunk Monkey]

No, you'll be fine. With J's you could even fit 35" (315) tires, but would likely rub off road. Like I said, your truck will sit high in the back. It really bothers some people.

piggybacking on...

850J fronts and 863 rears will equate to a level truck, even without bumpers/winch additions....and, down the road, adding those in tandem should also equate to a level truck....correct? (mental plan is to do the HD springs and force the issue of bumpers that much sooner )

Combine this with N73 front and N74E rear shocks....stablizer, normal CC bushings, damper, etc....

(yeah Dan, we had this talk this week....hard to write notes, eat dinner, and redial dropped cell service tho...lol)

 

[Trunk Monkey]

Yep, that combo will net you a truck that sits level. Dave Connors (dmc) just got an 80 with the 850/863 combo. He swapped in the J fronts and the truck sits almost level. When he gets a tire carrier on the back it will be level. I'll get him to post his before/after pics.

J's and 863s

Here is my set up per Cory's post. Woody I have the exact set up your referring to. The rear for me is a bit stiff in that I carry basically nothing. I am one of those people who do not like rake so once i add a rear bumper and long range tank I expect to be pretty happy with the stance.

Dave, looks like a slight rake with the J fronts and heavy rears....sharp truck....you do have the front bumper and winch tho, on my list, but more likely a bit down the road....from the look, a rear bumper/carrier outta level out things....

thanks for the pics!

More piggybacking...

So, correct me if I'm wrong:

850/863 with stock bumpers and an unloaded truck = forward rake.

850/863 with ARB/SLEE front AND SLEE rear tire carrier = still raked forward?


I'm gearing up a campaign to convince the wife that I need a new suspension. Thought I was going to go for the 850/863 combo, but now I'm wondering if I should go for 850Js and 863s. Not looking for more than a couple few inches of lift, but I would like a level truck--but not one that drops it but when I load up for a camping trip.

Sorry for the hijack, but there's still not a really difinitive discussion of the myriad OME options in the FAQs.

Doh.
You got those pictures in right before I got my post up.

Good looking truck.

Anyone got any pics of an 850/863 rig?

[Clutchee]

Boston-just go with the J springs! Wifes truck had 2.5 Med & after wheeling & camping in it we opted to go with J-springs because of weight we were carrying along with wanting the extra lift it provided.
*not to mention most people will lift a truck then see what they could have done & spend money twice trying to achieve what they could have done once!

JUST MY 02 cents!

[Hayes]

Man.

Sorry for not actually reading the post. My bad.

dmc, what else did you install on your truck to accomodate the 850J / 863 combo?
How does it drive?

I take it you're a Utard, no?

My before pic is 850/863 but with winch and bumper.

Here are two pics from CM this year with the 850/863 set up. The truck is loaded down with all my tools, camping gear, food and beverage for 2 people for 4 days. I'm sure every now and then i'll carry more but more often than not the load will be lighter. Still not sure why I had the spare birfs and inners for my 40 in my toolbox that trip.

Might try 850's in the front and 860's in the rear? The 860's are the same spring rate but slightly shorter than the 863's. On a light truck should net about 2.5" lift and sit level?

is another better/easier solution for folks planning to carry much weight in back or tow -but only infrequently- to get moderate weight springs giving a level truck and then adding air bags in the rear? Rather than planning on a rake when unloaded...

When Christo and I chatted on Tues, his recommendation for a stock front/rear bumper rig that towed was the OME Medium setup and airbags in the rear for towing....the "normal" airbags still work fine.

I'm still toying with too many options....building mine with mediums and running for another year or so, or "forcing" the front and rear bumper build project that I really don't have time for now, but want so desparately to do...lol

CDan said something funny when we chatted on Tues....some mumbo jumbo about only doing the work once...he forgets that I tear stuff down on my 40 just to have something to do...swapping springs would be a enjoyable evening for me


despite everything, I'll bet I just do the Med setup for now....might have the springs for sale used in a year or so tho
