Big update! I finished up my Titan Swap drop bracket lift this week. I'm at about 7-8" front lift and 5-6" rear. Basically, it's a full Titan swap that uses 2004-2006 titan brakes and hubs. The bracket lift is a Titan Rough Country kit that I custom powder coated. I built a powdercoating oven in my garage specifically for this, but that's another story for another thread.

Initial impressions are very good. Steering feels fine, which I was worried about after some feedback about the Fabtech kit. The ride is much more controlled than with the 1st gen Tundra 5100s (better damping from the 2.5" 6112s). I need to correct my axle mounting, because right now the centering pins push the axle forward. The wheels are noticeably shifted forward in the wheel well, and I have some contact between the tire and fender in that area.



I could get more flex if the rear tire wasn't bottoming out on the fender.


Greg at PRG built me some custom 6112 coilovers (2.5" diameter). They started as 2nd gen Tundra shocks with 650 pound springs. Greg cut and shortened the shock stem, then rewelded the lower eye to get the appropriate 23" eye to top hat height. Here is a comparison from stock Pro4X to 1st gen Tundra 5100s to the new 2nd gen Tundra 6112s:

These shocks have more travel than you can actually use with a titan swap. I built custom bump stops to limit compression travel and prevent the UCA from punching through the inner fender. They use Wheeler Offroad's progressive "Super Bumps". Of course, I sprayed a multi-layer candy powder coat over them 😁.


I matched the front coilovers up with some Bilstein 5165s and custom cut new lower shock eyelets for them. They are 255/70 damping rate, 28.5" long with 11.5" of shaft travel. I'm temporarily using 2" shackles, Deaver dual AAL, and 2" blocks to get the rear up. It doesn't quite match the front, but I'll get some proper springs eventually.

The wheels 18"x8", 23mm offset 2017+ Titan variety. Tires are 35x12.5r18 BFG KO2s. I should have regeared to 4.56 initially. The 4.10s and manual trans on 35s feels similar to 3.69s and 33s. Not totally unbearable, but low speed crawling is going to suffer.

I'm really impressed with the road manners of the KO2s. They are notably quieter than my Duratracs. Here is a side by side comparison of the 285/75r16 Duratracs next to the KO2s. In this pic the Duratracs are on a 7" wide rim and the KO2s were on a 9" rim.

Here is a bonus pic of my powder coating setup. My envelope is something like 36"x20"x14". The drop bracket components just barely fit.

Weird question but would you be able to measure the length of the RC knuckle? I have been wondering the knuckle length on this and the rancho 5 inch for some time know, curious what the difference is between this and my calmini knuckle. The stance you have is nice and wondering if I would gain much more lift/clearance than I already have.

It's about 26". I'm not sure what the Rancho or Calmini knuckles measure, but I'd be interested to know if you find out.
