OME 2864 or 2868 rear springs on my porky girl (1 Viewer)

[asutherland]

Hey all

I'm looking at the following:

FRONT: ARB2850J front springs for a total of 3" lift
REAR: ARB2864 or ARB2868 rear springs + 25mm spacer for a total of 3" lift

Plus ARB60071L and ARB60071L for shocks


So it's a toss up between the two rear spring setups. I don't believe the rear J's will work for me as the weight is too much. Without being loaded up she's ~ 7k lbs.

1HD-T diesel engine, dual batts, york210, etc
Front steel bumper and winch ~220 lbs
iKamper RTT, 270 awning 200lbs
Custom slide-out kitchen ~200+ lbs
30-40L drinking water ~85lbs
Factory sub-tank with fuel (50L diesel), ~120lbs
35" spare tire ~60lbs
Rear bumper with swing-out/propane jackall etc ~250+ lbs
2x steel skid plates
Steel sliders
Recovery gear, tools etc
Full off grid gear for family of 5 for a week+

I originally was set on buying the Dobinson's 2.5 VT (variable tapered) lift but waited too long - stock is out and prices are up. Not to mention $$ border fees and shipping. OME is easier to obtain here in Canada, and much cheaper. My current suspension is incredibly under rated for what I have in the truck, and worn out, and needs to be replaced ASAP.

I'm not looking to start a suspension thread because there are plenty of those already. Just curious on opinions of the 2864 vs 2868. Wasn't able to find much on here re. the 2868. Hoping an Old Man Emu specialist might be able to chip in! Thanks!

Anyone?

You can go J springs all around with a spacer in the front if you are heavy.

While the J's will probably do fine up front, I'm concerned about the rear specifically as I think that's where most of the weight is concentrated. 3400 KG is a LOT of weight.

I'm definitely leaning towards the 2868s in the rear, with a 24mm spacer to match the 3" J's in the front. With L shocks all the way around...

I had J’s all around. I ended up going with Slee 4” springs. Didn’t go with heavy’s in the rear. I wish I had went with Slee’s from the start. Slee has the heavy rears which my friend is running and likes them. I didn’t like how the J springs rode without being loaded up. I’m at 6,300 lbs without camping gear. The slee’s have a more controlled ride and and significantly reduced the extreme sway I would get with the J’s during lower speed rutted roads. I had the same shocks with both sets of springs. The slees flex very well also.

Another vote for Slee Springs. I’ve got the heavies in the rear. Truck rides so much better loaded. A little harsh empty but I don’t daily drive her.

Agree with Slee's if you're always loaded.... I run 64's with a 20mm Packer on my current rig and it sits well but I'm only 2 1/2".... I had the Slee's on my 40th and the ADS/ Slee shocks and it was a great combo......

Agree as well to go with the Slee 4” Heavy Progressive rear. At 7500# like your pic shows, it should put you near or just above 3” of lift (23” hub to flare).

Slee set me up with OME X-Heavies in the rear (not sure the p/n) in knowledge of an estimated 600# @/behind the rear axle.
I'm still short the 40L of water weight in the tank and there is already a tiny rear sag. The front end has tendency to lift in response to the rear compressing.
Unloaded 'Smitty' rides like a school bus on road, but that's the trade off with simple, sealed shocks.
Loaded up and off road tho...plenty satisfied with the springs (and shock's) ability to deal with the dynamic loads.
Figure a 25mm spacer in the rear will resolve the sag without too much problem.
