Need advice on rear spring choice
 

Looking for some advice on rear spring choices.

Current setup:
F: 5100's in 2nd notch with 2883 springs
R: 5100's with 2895e springs

New setup:
F: 6112 w/ heavy load springs and 1/4 or 1/2" top spacer
R: keep 5100's or get icon 2.0's Springs: ??, or MT extended travel kit

with the current setup and all the additional weight it is sagging quite a bit so I figured its time to upgrade. current fender to hub measurements are: 21.5F, 22.5R

Weight:
F: Warm bumper, winch, dual AGM batteries, ARB twin compressor, Magnuson Supercharger. Est 250-300lbs

R/center: RSG Sliders, RSG full steel armor underneath, rear leveling platform, fridge with slider, 8" sub, recovery gear, tool kit Est. 200lbs extra

I would like to end up with 3-3.5" front lift and 2.5" rear lift with all the current weight.

Current options I am looking at are OME 2896 or 2898 springs, Toytec Flex HD springs, or the Metaltech Extended travel rear kit with either medium or heavy springs.

Any advice appreciated.

My first suggestion is post this in the Dobsinon's thread and have Mike make you a suggestion on rear coils. You can still do your front setup and rear shock the same but Dobinson's has the most options for rear coils and Mike is fantastic at understanding your needs and making a solid suggestion. Metaltech is also a very good reference.


On a totally separate note, I would seriously reconsider lifting that much. The front IFS really isn't going to preform optimally with that much lift. You'll be sacrificing a lot of down travel. My opinion is stay at 2-2.5"

Also, I would lift equally in the front and the rear. If you eliminate the factory rake it will look good till you add any weight to the rear the you will have reverse rake which obviously looks goofy.

Yea I did look through the dobinsons thread but they dont have as many rear spring options it seems. especially in stiffer spring rates. the 2896/2898 are 318lb springs which would help with the weight.

The 6112's are sitting in the house already just waiting for install lol.

Yea i would like to do an even lift with 3" f/r if possible. I like that the metaltech kit has extended downtravel. I guess I didn;t notice after adding all the weight how low it currently is and i've already lost uptravel due to the sag in the current setup. I also think even with heavier springs I will get some sag due to all the weight. I forgot I also have an SSO rack and carry a RTT when camping.

yeah man, dobinsons is the way to go. They have both 2 and 3 inch rear springs.

I'm running 2 inch c59-329 for my super heavy rear butt....but they do make a 3 inch if i wanted to go extended travel.

I think they make a slightly not so heavy version c59-327 and a extended version of that too...

I've run toytec super flex and HD versions and still sagged, or was way undersprung and bottoming out on the trails. Went with dobinsons and am pretty happy.

As Comtn4x4 stated, i wouldn't go 3 inches either. I went full circle. Went with 3 inch and 33 to 2.5 inch and 34's to make up the difference. Believe it or not that 1/2 makes a difference...better ride quality, better grip, less sketchy during off camber drop offs.

yea a 2.5" lift F/R would be ideal. I am thinking the 6112's with heavy spring and 1/4" spacer will get me 2.5" after sag from weight. As for the rear it seems hard to find something in the middle. I'd like to go extended travel in the rear as well if possible which is why I was looking at the complete metaltech LT kit with either medium or heavy springs.

Dobinsons all the way!!! Call them or message them on their thread they have here. They have what you needs. Their Springs are superior to all other manufacturers. Icons came with my KING lift that I purchased. I had also ordered a set of Dobbinson Springs. The difference was ridiculous. More coils and heavier material. Needless to say I sent the Icons back. The ride quality is also excellent.

debating between 675 and 677v springs currently. I saw you had the 677v and was wondering if you think I would get too much lift with only 200-250lbs extra in the rear(larger spare, fridge/slider, leveling platform, tools, rack, armor and sliders)?

I did run the 677v before I switched to the 701v. IIRC the free length of both coils is the same so really it will be how much sag you get with them but I'd ask <!-- BEGIN TEMPLATE: dbtech_usertag_mention --> @Crikeymike <!-- END TEMPLATE: dbtech_usertag_mention --> about that. They will settle some but it takes quite a while. 500-1000 miles. On my rig the 677v was great when unloaded/day to day driving. However, when loaded to head out it was reverse raked. I do load up pretty heavy when the whole family and dogs are with me. Switching to the 701v has resolved that. The unloaded height didn't change but the ability to carry the heavy load improved. I think my actual lift in the rear ended up being 2 1/2" over stock. Obviously we're not comparing the same coils but I'd think it would be similar. My opinion is go with the stiffer coil. Seems like I am always finding another thing to make my rig heavier so it's kind of future proofing. And as well once you add your tent and gear to head out you'll probably want it. Rear coils are pretty easy to change and relatively cheap so if it doesn't work you can always swap them. Getting suspension dialed in is something of an experiment.

And actually I see you are near me, I have my old 677v's in the garage if you're interested. (I'm actually in Lone Tree) They have maybe 5,000 miles on them.
