With full recognition of the abundant lift-related threads in the FAQ and beyond, I still can't settle on a satisfactory answer to the question that is rattling around in my vacant head:

What are the specific tradeoffs when increasing your lift with spacers, versus putting in taller springs.

Hypothetical example:

OME 850 N74 front end with a net 2.5" lift.

1. Add a one inch spacer and N74L shocks resulting in a 3.5" lift.
(Pretend that switching to L- shocks matches the additional lift perfectly)

versus

2. Switch to 850J springs and N74L shocks resulting in a 3.5" lift.


Throwing on spacers is obviously the budget solution to getting a little more lift.


I'm exploring the option of adding some spacers to my 850 and 863 OME springs. Burly Slee bumpers (the front is heavier than an ARB), 9000 lb winch, tire carriers, and a heavy cargo box have got my truck sitting almost level at about 2.5 inches front, about 3 inches in the rear. I haven't measured it, but when loaded up with family and associated camping gear, my lift begins to disappear. I plan on adding sliders sometime next year as well.
If I can add an easy inch with spacers (and L-shocks if appropriate), without losing travel, I'll do this sooner than later. If saving up for J springs or even something non-OME (FOR would be sweet) is significantly better, maybe I'll do both--spacers and new shocks (maybe even FOR eye adapters) now, and new springs sometime later.

Edjumucate me about running spacers.

I'll edjumacate you, Ryan...
get the new J's, and set me up with the old springs for my 80 :)








Kidding! You are my hero Hayes
 
well, there are spacers and then there are spacers...

you can just put in a cheap rubber spacer on top of the springs. Easy to do. But it'll squish rather quickly per posts here. Some better ones are available MAF, SOR etc but more expensive. Plus the spring is lowered wrt to the bumpstop so the latter may no longer be long enough (depending on shocks etc).

Or you can get the fancy metal spacers that you put in on top of the bumpstop. These lower the bumpstop so that's no longer an issue. (I'm running Christo's right now, real beauties...). Cory's were also very nice. I have a pair of those too.


Of course, if you run shorter springs with spacers and you're very heavy you could in principle squish the springs closed more readily than if you run longer more open springs of the same ratio (in reality not likely I would think, with bumpstops etc).

I went with the notion that I'd put spacers on top of the springs to see what would happen. When I'm sure all is well (height, caster, vibes etc) I may get longer springs. I'd hate to get longer springs and realize I'm in trouble... The springs are relatively easy to sell here actually, but the shipping costs are high compared to the spacers. Plus it would be smart to keep the spacers anyway since you'll inevitably want higher later on... :D

The typical tradeoff of a spacer vs. new coils is a spacer is static, so you aren't increasing the uncompressed length of the coil, and you also aren't increasing effective spring rate for the taller lift. For 1" of lift, this is fairly immaterial IMO as long as you aren't also trying to significantly alter suspension travel (L shocks on OME medium with a spacer would fall into the category of "significant" as they add 2" of down travel and may fully unseat your coils even with the 1" spacer).

In other words, if the extra lift is just for lift, and not for extra suspension travel, I wouldn't spend a penny on new springs. Now if you have suspension and/or tire goals, you really need to look at it as a system.

Same old story: are you moving to 35's and therefore need to space travel away from the body, effectively increasing down travel and wanting springs that match properly to the range of suspension motion? Or are you staying with 33's and want a bit of extra lift? In the latter, just get the spacers and forget about L shocks. In the former, lots of options (FOR/Slee/J's 'n L's), none of which IMO involve keeping any parts from your OME medium kit.

Do keep in mind that going much over OME medium really puts caster at the low end, and you'll probably want to address that eventually. I don't mind it, but I will eventually do the "washer" mod and a DC shaft because there is no good reason to live it except budgetary.

BTW - just looking visually, I think J's are more than 3.5". They are taller than the FOR kit unless my eyes deceive me as comparing my "unloaded" rig with FOR to rigs with just J's and winches/bumpers the J's are still a bit taller.

Would any of you guys mind listing a few sites where a newbie like me can order spacers that ship internationally?

I just need to top up a bit to get Elsie's fat a$$ off the sand :D
