Second Gen Lift

Could I get some help with measurements here? I have a 2013 crewmax and just installed Elka suspension, Alcan Springs and coachbuilder +1 shackles.

I finally got my front coilovers adjusted and the front end aligned and may have a rear leaf spring issue. Does anyone have stock measurements from the center of your wheel hub? All four corners would be even better.

I had Alcan make the rear springs 1 inch over stock and I'm starting to doubt that happened. At least on the drivers side. I have coachbuilder +1s. Those are good for .625 inches of lift. So I should have a total rear lift of 1.625 inches. I know the shackles are doing their job.

This is the final measurements from the center of my wheel hub.

FL 24.625 FR 24.75
RL 24.75 RR 25.25

You can see the rear driver's side is a half inch lower than it should be. And honestly im not sure the passenger rear is making the cut either.... Although I could be wrong.

Hopefully someone with a 2nd gen can help. I used to have these numbers written down before my first lift, but can't find them.

 

I took the Alcan springs out and measured. They both had exactly 6 3/4 inches of arc. So... At least I know the leaf springs don't have a problem. The front end is level within 1/8 of an inch. I guess it's either the weight or the way my truck was manufactured. If anyone has the stock measurements from the hubs, though, I'd appreciate it.

 

I don't have stock measurement without fender flares. There's quite a bit of variation in how much lift one actually gets. Mine is lifted 3.5 in the front and 1.5 in the rear. My rear is 1/8 inch higher than the front and my truck looks like it's nose-high. That's just the way the truck looks, I think.

 

That doesn't seem too bad at all. Remember you have your gas tank on the driver side. I'm at 25in in the rear on driver side and 25 1/2 on passenger side. Use Deaver u748's that are +2in and lots of extra weight with a steel bumper, rack, tent, and 2 spares.

 

Thanks for the replies. I need to whip out the tape measure again. I'm stumped as to why, but after I reinstalled everything, same places, my rear end looks like it's level now. ill iave to measure to confirm that, but I'm pretty sure about what I'll find.

The only thing I can think of that I did differently was getting the truck on the ground before I torqued the shackle bolts. They were moving before, so I don't think that was an issue. I have no idea.

One think I learned from David at coachbuilder, was the relationship of the front coilovers to the rear height. I may be the last person to have learned this, but I'll leave it here for anyone else.

When you add a shim or adjust a coilover to raise or lower one side up front, the opposite rear corner is either raised or lowered.

Example: if you raise the front left coilover, your right rear height will be lowered.

Anyway, this thread may not be helpful to anyone, but I'll post the final measurements as soon as I can.

 

Your stock measurements for the Tundra are suppose to be 22 inches in the front and 24-24.5 in the rear. So your measurements would be getting 2.6 inches in the front and not very much for the rear. I know the driver side is always a bit lower since the gas tank is on the left side. I wonder why you arent getting very much

 

Are those measurements for a 2nd or 3rd gen tundra? I've had people tell me 23.5 and 24 for the rear also. Seems to very quiet a bit.

As far at the front goes, I was shooting for 2.5 to 2.75 inches. So that worked out nicely. The rear was supposed to be 1.5 inches, technically 1.625.

I may end up buying my third set of coachbuilder shackles, +2s. So I'll probably put my +1s and +3s up for sale.

 

07 to current Tundras are the same measurements but the 18 and 19s have been a bit different.

 

I would think 07 to 13 would be different than +14 on up. Different fenders

 

We've measured several of the 19s as well just to make sure they've kept it the same and they have. Sorry I'm Anthony over at Toyteclifts, we do these all day lol

 

I have an extra coach builder shim 1/4” on the drivers side to avoid the ‘Tundra lean’

 

Oh ok, cool. Yeah, I need to re-measure my rear since it is leveled out. I think I'll be close to an inch and a half lift in the rear when it's said and done. You guys selling many of the Elka kits or your aluminum version? Between the full Elka setup and Alcan springs, its a night and day difference. I'm really enjoying them.

 

I used shims on my last lift, but decided to leave them out on this one. I'm starting to believe the reason I was having trouble with the rear leveling out was because I torqued the shackles while the truck was in the air. When I broke loose the rear suspension, I believe it let my front coilover adjustments take place to level out the truck. Worked like a charm.

 

Oh cool trick

 

Not something I came up with on my own though... David from coachbuilder taught me about the relationship between opposite corners of the truck and ride height. And @ColoradoTJ taught me about the truck acting like it has some kind of preload when you torque nuts while the truck is in the air.

I thought I knew what I was doing. Turns out I was just a chimp with a wrench... I'm grateful for all the help on this forum.

 

Just an update here. My rear end went back to leaning towards the driver's side a bit. The front settled about 1/8 inch on both sides. Even though it wasn't much of a difference in the rear, I couldn't stand looking at it.

So I found something that fixed my problem on the @Toytec Lifts website. This half inch shim/block. At first I was not excited about this idea. But the more I thought about it, I realized a half inch shim under my driver's side suspension wouldn't be a problem. So my final measurements are:

FL 24.5 FR 24.625
RL 25 RR 24.875

So... Of course I can't leave things alone. I've decided to buy my third set of coachbuilder shackles. Right now I've got +1s (.625) and I'm ordering a set of +2s (1.25). That should add .625 inches to my rear measurements.

My rear Elka shocks are made to work with up to 2 inches in the rear. So even if the rear stock hight was 24 inches, the extra .625 inches from the +2s should work fine.

Thanks for the info, Anthony @StrmTroop29
