Kings and spacers

So im looking at getting a set of kings for my 16 pro. The last set I installed on a truck came set right around the 2.5" lift mark. I'd really like 3" of front lift. Would it be better to preload the coil some more or use a shim from coachbuilder?
I run one shim on each side of my factory pro set up now and didn't see any negative affect.
If it matters I will be getting the extended travel kings from filthy motorsports.
Thanks

 

They are adjustable

 

Yeah I know that, thats why I asked if it were better to adjust the spring some more or add a spacer.

 

I would adjust it myself. The ride will be better at 2.5 inches vs 3 though, sometimes that extra little bit of downtravel helps

 

I would get the extended travel kings and add a little more preload, accutune off-road has a chart on their website measuring from the top collar to the bottom eyelet for the ideal ride height/quality, depending if you're going to be off roading I would not add the shim as the axles and steering will extend more during full droop and the shock will bottom itself out before the bumps, aftermarket coils were not designed for using shims.

 

Just add preload. .5" of ride height is only a couple of turns.

 

Kings come with 600# springs. You can also swap these for 700# springs and then you would need to add less preload.

 

Great point.

 

NOT a great point. Adding a heavier rate spring will not lift your truck more, in fact it may make it ride much worse. Don't over spring the truck just to avoid preload. Preload is a good thing.

Also like mentioned above, don't add spacers on top of the King coilover. You would be making the extended length on the coilover much longer and this will affect the steering geometry, cv angles and may cause the spring to hit the control arm, you also would need a bump stop spacer to keep the coilover from bottoming out.

 

Do you want more lift for clearance reasons or just cause?

 

I really appreciate you guys being here for advice. Maybe it's 'cause I'm LT but I run 700lb springs though even before, with MT, I ran 700lb springs. 700s are a fairly common application for the '07+ Tundras. I'll definitely listen though if you guys think different. Several of my LT friends are running 800lb springs but their trucks, loaded, are really heavy.

 

Well there i have it. Seems like a good enough answer for me. I'll check out the chart on ride height vs comfort.

Possibly both. I'm running 295 70 18s right now and just clear everything I need to clear. I'm looking to move up to a 35 12.5. Just want to make sure everything clears. Also my front is ever so slightly lower than the rear, want to level it off

 

I sure hope someone chimes in with a full answer, I too could use some knowledge on spring/preload vs spring rate

 

Don’t forget if you get extended travel coilovers, you have to get new UCA’s as well that’s an added cost. I’m on stock UCAs kings 2.5’s all around stock how it came in the box and I love them the way they are. Plush on the street and smooth off-road even when all 4 tires are off the ground. I vote leave them the way they are but you might have to adjust the driver side for the lean.

 

I run 700# springs on my Kings with zero issues, 2019 truck rides great on 37's. Everyone who gets in, comments on how good it rides.

 

I guess I just feel if I'm going to do it I might as well get the extra travel. Cant say I know ill ever need it but just don't want to wish I did it down the road.
And my truck has never had the drivers side lean. Stock it didn't and with my coachbuilder shim both sides sit dead even without a driver

 

It all depends on what you are really gonna do, that’s your decision. I can go 65mph on fire roads with some dips and didn’t feel like I needed extra travel, I also took off the front sway bar. Only on continuous whoops with varying sizes did more travel benefit me but that’s a specific case.

 

At 3” if lift you may need UCAs in order to get a good alignment. If you need to get UCAs anyway, IMO, you might as well get extended travel kings.

 

Another truck saved from the shims

 

@94slowbra

What wheels you running?

35s fit with proper wheel offset, proper alignment with as little as about 2.5" of lift on a 3rd gen.

Possibly, if running stock wheels and thinking of upgrading those in the future, look into upgrading those now and keeping the Pro suspension.

 

Thought these trucks come with 700lb springs? My foxes came with them. 600 seems to soft for the size of the truck.

 

Fwiw

 

I'm running Method 18x9 with a +25mm offset. It may fit but I also really want the truck perfectly level and the extra 1/2" is what it will need to match the back. Do I need Kings, probably not. Do I want them for just incase, hell yeah! Plus I want a true 35 and these should help with clearance
I just installed some kings with spc arms on my uncles truck and its a great set up. It got me thinking

 

This is what I dont get....you already spent a lot for the suspension and want to change it out. Sorry, I just dont get it. Might as well go balls out and get their 3.0 kit.

Why not shim it, toss a bump stop spacer - toss on 35s and call it a day?

 

Wescott makes a nice preload shim, it's not a top plate spacer.

 

Because I love modding man. I've run this set up for the past almost 3 years and I'm looking for something new. I just did a king set up on another truck and I liked it so I figured I'd give it a try.
Ofcourse I could add a shim to my current set up and probably be good to go, just want to try something new

 

Ok, I can understand being bored and the itch to burn some cash and change things up. That being th case, I stand by my balls to the wall - go 3.0 and really mix shit up.

 

Fox come with a 17" x 700lb spring, for stock weight sometimes we will go down to a 500 or 600. Depends on weight of the vehicle. For a long travel kit, with a larger motion ratio and more weight added, a 700 or 800 may be needed.

 

I don't understand you guys who chase a perfectly level truck. You know once you sit in it, or drive on a road that isn't flat, or hit the gas hard enough, or get low on gas, it's no longer level. Its almost like combing your hair before driving a convertible with the top down.

 

Funny, I have a vert too, and I always do my hair before I leave! Just want more front lift to match the rear, thats all
