Here’s some measurements I took today, measured from the ground to the bottom of the fender.
I think its important to include spring rate front and rear, tire size and pressure (or height as installed on the vehicle), just to provide some context.
BFG KO2 275/75-17 - tire height measured on vehicle - 31-1/4” tall
Preload on passenger side: 2.5 threads
Preload on drivers side: 0
Front coilover spring rate: 650
Rear spring rate: 315
Passenger front:
37-3/4” @ 230bar approx. 32psi
Driver side front:
37-1/4” @ 230bar approx. 32psi
Passenger rear: 39-5/8” @ 240bar approx. 35psi
Driver rear: 39-1/4” @ 240bar approx. 35psi
Truck looks fantastic. How does it ride?? I went with the King and have a front SSO slimline bumper and Winch, RCI sliders and Skids. The folks I ordered from didn't think I needed higher spring rates. They are 550. I had to crank major preload in, like 12+ threads, and still its got major rake. I get crazy nose dive, worse than my TRD set up.
IO have the 650 springs and I'm putting them on this eve.
I have a 2005 T4R and I am ready to upgrade to the king set up. I am currently running 5100's all around set at 1.75".
I have read through hundreds of threads and am trying to find some advice on what would work best for my rig.
I have no extra weight as its my DD, I want to have a level ride and would not mind a 1-2" lift front and rear. understanding that the kings with the 600lb springs up front would give me about a 2- 2 1/2 over factory but I cannot figure out the rear. with no extra weight daily, would the 2" superflex from filthy motorsports give me rear rake? I do not want to crank on the front coils to get lift so I can keep the ride on the road nice and smooth.
Long story short, just a little advice with spring rate front and rear.

Can you guys please list your final front ride height measurements, fender to ground?
I'm at 38.5 on driver and 39 on passenger on 600 pound springs - truck rides like ass - too much preload and my shocks are bottoming out.
I'm going to lower the front 1 inch on passenger and .5 inch on the driver this weekend and remove the internal spacer from the front shocks to get more travel.
So I am about to pull the trigger on Kings for my ride from Total Automotive. I am looking to get their "5GenK Stage 2A" kit while these black friday/cyber monday deal is going on. It comes with Icon delta joint UCA's. And I also plan to get Dobinsons C59-725 rear coils. The kit comes with 650lb extended travel coils and was looking to get 600lb instead. I PM'd Total Automotive if I can switch out the coils and they said just to mention the coils I want while checking out.
I would like any thoughts about this setup. I don't plan to add any front bumper upgrades, but want to reduce the brake dive as much as possible without the ride being too harsh. If I was to get a front bumper. I would get the C4 low pro bumper to retain that stock look that I like. But that would be a maybe. I already have C4 sliders and TRD skidplate if that makes a differance in weight for the front. I choose Dobinsons for the rears because of the idea of being offset to compensate for the KDSS lean. I just don't want to bother with adjusting the front coil or add any other spacers to correct the lean. I don't plan to add too much weight back there. Just keep my tools and recovery gear while daily driving. And any camping/off road gear when I do have time to go out with the family. So any thoughts?
P.S. Sorry for the long post.
ok guys I got my issues resolved.
solution for my almost factory weight truck:
wheelers t13 + one 1/2 inch spacer on the driver
600 pound king springs + 1 shim on the driver
reduced nitrogen pressure a little bit
reduced preload from 8 turns on 550 pound springs to 4 turns on 600 pound springs
rides much better now.
final ride height is level 38.5 on all corners.
thanks to everyone that helped me try to troubleshoot my issues.
moral of the story -> preload = bad.

Glad you were able to get it all working together well. Proof that the amount of preload makes a huge difference in the way a suspension performs. It’s always a good thing when you can change out a less expensive item (in this case springs and a little bit of nitrogen) to correct an issue.
BTW, do you not have the adjusters for your shocks? Or were you already at the softest setting and you needed to drop more pressure? What technique did you use to bleed the nitrogen?
