I put them back in so it wouldn't be so embarrassing driving around but that extra height drives me nuts; I can almost swear they add upwards of 1/2 inch instead of 1/4 inch even though i know better (stupidly didn't think of taking before/after measurements to confirm this afternoon)
I would love to even out my rake even just slightly but I really don't want to carry around a bag of sand or gravel - been there-done that, a year later I'm STILL vacuuming up sand and pebbles. Anyone got a trick up their sleeve? I'm assuming not since solid axles are dead simple and there's not really much to hide but I thought it would be worth asking regardless. I heard one user tried to slip a piece of tubing over the top of the coils which sounded like a smart idea, but apparently it fell out pretty quickly (and I imagine zip ties wouldn't last long with constantly rubbing against the body)
What I wouldn't give for these coils to be a hair shorter.... If they were wrapped a little differently I probably would've taken a sawzall to them by now honestly. Hell I'm still considering it a little bit, but I'm not that cheap and will probably get some new front coils if I can't think of anything

901 coils are for the rear of 2nd gens. 906 coils are for the rear of 3rd gens

For a close to level, daily driving, some wheeling, without lots of weight (stock skids and such)on a 2” lifted 3rd gen, it’s almost perfect. It’ll hit the bump stops more and more as weight in gear and armor goes on.

The 2890 ome did add a lot of lift though. Definitely has a rake now even with weight. I’m starting to rebuild the front end with all new Toyota lower arms, JBA uppers, and I’m planning to move the 6112 coils up to the 2.3” from 2” to see if that gets it about at the right ride height. It’s really cushy thought for the high speed rally stuff.

The 2890 did reduce the bottom outs greatly. It feels like a lot of travel was added since it’s not constantly hitting the Duro bumps now. A sway bar adjustment was needed though, which helped the added body roll greatly. I have an eimkeith PCK on order to hopefully alleviate the body roll since the added ride height with the 2890. I’m sure the rear end bushings are also shot.

I loved my 890’s when I ran them. They don’t have enough free length and high enough ride height for my setup, and like you said, they get overloaded quickly just because they don’t sit high enough to keep off my extended bumpstops & longer compressed length shocks when you have any real weight in the back. They work best with the 4Runner 5100’s or similar ext/ comp length shock from my experience. That way you do without the bump extension and maximize their bump travel before making contact with the axle.

There’s not much for options between 890’s and LC coils ride height-wise unless you’re mixing trim packers and/ or spacers. I wanted to try the Dobinsons but they seem like their options are just like the older aftermarket offerings (ARB & Toytec primarily). Either too short or too long for my ride height and spring rate preference. That’s why I settled for the older Toytec Superflex even though they’re a 240 lb spring rate and would have preferred 200-220 ideally. They have plenty of free length to prevent dropping a coil when using the longer travel shocks and also sit at a decent ride height to avoid contacting the bumpstops too easily and don’t sit at 4”+ lift unloaded. I had to settle on a heavier coil to get the other properties I needed out of a rear coil.

It’s a game of give and take the way the rear suspension on these vehicles work.

I plotted out the spring rate, and even though the 890s spring is a lighter 190 rate, the addition of free length comes into play and ups the ride height at a given load much better than the 2906.

Some force examples.

190x3 =570
220x2.59=570

190x4=760
220x3.45=760

I do sometimes wonder if a 220 rear spring rate is probably a better match for the 600 pound front spring rate with my 6112 shocks, slightly at least. But the issue is is getting the right freelength in that spring rate. Even when you go to the 891, you get a shorter spring.

Other reason for my decision to go with the 2890 was the sales guy at Wheelers said a coworker had 2891 springs in his 4runner and it rode like crap since there wasn’t hardly any weight on it. He said you better have some bumpers and a drawer system, otherwise you won’t like it. So I went the 2890 route.

My thinking was the rear springs are cheap enough to replace when/if I cross that bridge.

The reason I started this thread was to basically gather data, start discussion, and chat about the “perfect rear 3rd gen spring”. I still think a coil that rode like an 890 but had a longer free height would be a great rear spring option for our trucks. ~2.5” of rear lift with a small/medium load and the ability to run longer shocks would be so nice, all while keeping suspension geometry closer to factory at its static height. I should look into a GB for getting a custom run of springs made. I wonder who Toytec uses to manufacture their springs…
