Fj80-Swapping out icon stage 3 rear springs for heavies...but which ones? (2 Viewers)

[TYM4FUN]

Doesn't seem to popular on here, but my TJM heavy's have been awesome with weight. 2,300lbs here.. 40k miles on the springs.

37

forgot to ask, can you give me the hub center - fender lip measurement please?

Both front and back are right around 24"

I swapped mine out with Slinky HD heavy...much better now.View attachment 2717293

The 35's are looking gooooooood!!!!!!

I can do that when i get home tonight. I also have 30mm spacers on all 4 corners as well.

Good info, so you essentially have a 5" lift from the sounds of it.

i think with the extra weight, the Icon 3" springs gave me about 2.5" of lift, without the spacers

..the new 35's

Thanks for everyone's feedback. Quick update- I'm now running Icon stage 3 shocks front and rear, 3" Icon springs in front and Slinky heavies in the rear. The ride is noticeably better with the slinky springs. I tossed some 315x75r16 Duratracs on as well and everything fits....but barely. I've got about .25" of clearance between the rear tire and bumper at full articulation -so 35s definitely would not have worked with this particular tire unless it's just a pavement queen.

congrats on your suspension upgrade. Could you please tell us the hub center to fender lip height dimensions for all four corners?

Cheers

those are good #s. Please update after you load up the rear before heading out for a trip.

will do. I'm heading to Ouray/telluride this weekend fully loaded. should be interesting to see

 

[alia176]

Awesome, you'll have a great time. There weren't any UTVs on the main road in Ouray and only a handful on the main road at Silverton when we were there last week.

I'm particularly interested in how much your rear end sags with camping gear.

Cool, hopefully we'll have the same luck. Yeah, I'm also curious about the sag. I almost went with the extra heavies given all the crap I have, but didnt want a super ridged ride when not fully loaded, since I'm not fully loaded as much as I am empty.

Would you mind providing the link for your Slinky heavies please? I didn't want to google it and then assume things. Thx.

Yeah, I actually called the official distributor directly, Mill Creek Overland, and ordered over the phone because they didnt list the springs individually outside of a kit on their site. They were amazingly helpful, had great service, and shipped right away:
