I had a bunch of different setups on this 4R over the years I owned it - I don't remember for sure in those pictures what it was set at.

It's a 2015 Trail Edition with KDSS. (old TE is the same as TRD OR now, new TE is an SR5 + appearance package, not sure why Toyota recycled the name.)

Front was Fox 2.5 RR Factory Series set somewhere between 1 and 3 inches of lift depending on the year. Rear had fox 2.0 shocks.

Rear springs were a variety of stock height plus Airlift helpers, Stock height plus Firestone Airbags (better than airlift in this application), GX460 air springs with custom adjustable air system, Dobinsons 2.25" KDSS coils (no longer sold IIRC) and stock coils with 1.5" spacer plus firestone air bags <- that was my ultimate favorite setup for rear coils - just the right amount of lift, softer coils = more flex and better ride, air helpers for when I'm towing/hauling.

You can see about how well it flexes in this video. Does really well IMO on stock coil spring rates.



I towed a few thousand miles with the 275/60/20's too. Never had an issue with them. Doesn't mean they're the best choice for you. Just something that worked for me.
