Tundra 6112 Bilstein On 3rd Gen. Info & Install

[Ron Burgandy]

is it possible to run stockish ride height with the tundra 6112? my stock front shocks are destroyed and am gonna replace them with a shock that I can adjust later when I’m ready for a full lift.

Yes Ron, if you look at the pics 99 posted on the first page you can see the grooves or perch's on the 6112's. There are 8 of them and depending on what one you choose to place the lower spring mt on it raises or lowers the ride height. Second to the bottom or bottom grove should provide you with stock height.

I talked briefly with a Bilstein Tech, as was to be expected, he couldn't give me recommendations on this setup due to liability and the fact that they haven't tested it (no one has). He did however confirm that the 1st gen Tundra 6112 uses a 650 lb spring, and the 3rd gen 4runner uses a 550 lb spring. A little more research showed that the 2nd gen Tundra Trd Pro uses a 600 lb spring.

Are the 6112 struts the same between the two? only the spring changes? or is there a stroke length difference also?

I'm doing a ton of research for my lift that I plan to do this winter, so this is very good info. One question that may possibly be dumb... Why did you install it at different notches for driver and passenger side?

So the Tundra one has significantly stiffer valving, and it also has a slightly shorter compressed length.

This was to make up for the extra weight on the drivers side with the fuel tank.

thanks, I'm having trouble finding comparison data between the two.

So after driving the truck some more, I think the spring rate is a little higher than I would like. For someone who does high speed off roading frequently, or prefers a firm ride with enhanced handling, I think the 650 lb coil would be perfect. I however, drive around town and highway a lot, so I think a lighter spring may suit my needs better.

A little more research showed that the 2nd gen Tundra Trd Pro uses a 600 lb spring.

Now, I'm not sure why they chose the 650 lb spring for the 1st gen Tundra that weighs less than the 2nd gen Tundra.

So with all of this information, I think I have decided to swap to a 16 x 3" 600 lb coil. We'll see how that goes.

Your post pushed me toward 6112’s but 4runner setup just wanna say thanks and also I thought the spring rate on the 4runner setup was at 600lb? Wheelers Offroad lists them as 600lb springs?https://wheelersoffroad.com/i-30632541-6112-height-adjustable-front-shock-and-coil-pair-for-1996-2002-4runner-47-258624.html?ref=category:1388356

It would be awesome if we could get the tundra shock with 600 lb springs. From that description on wheelers website it seems like that might be an option. I haven't done any calling around just yet, but I think that might be my next front end setup since I'm needing a bit stiffer valving and a bit more spring rate than my current setup. Especially when I finally add a winch to my setup.

Since you replaced your springs with King springs maybe you would know; Would the Bilstein springs fit on a 2.5" coilover like King, Icon, etc?

Was this question & answer regarding the 6112 struts between the 3rd gen 4runner & 1st gen Tundra?

Yes, So the 1st gen Tundra has stiffer valving in the shocks then the 3rd Gen version.

Was the Tundra 6112 a direct fit or did you have to change the lower mounting bushing?

Tundra one is a direct fit using the stock bolt. The bottom mount is WAY beefier than the 4runner 5100. Just use your stock top hat and the whole setup will bolt right in. Just have to decide what spring to run.

Do you use the 4Runner top hat rubber isolator as well or a Tundra top hat rubber isolator with the 4Runner top hat?

Yep, 4runner one works fine.

How do you like them now and what springs are you using with them trying to get something better to pair with some lc 9 wraps

Tundra 6112

Hey, love your posts. How are you finding 6112 now? I'm looking at tundra or 4runner set up. Will not be getting a bumper until I get a good deal but definitely would love one. Right now it will be stock for a bit. Suggestions ? Would you recommend tundra or 4runner 6112. Do you think you can still get 2 inch lift on the tundra 6112 with stock weight ?

Bumping this because I get tons of questions about my front suspension and unfortunately I went for the 4runner 6112s with a 650lb spring. Hindsight 2020 i shouldve went for the Tundra 6112s as I have full skids, plate bumper, winch, and could use the extra 1" of extended length over the 4runner 6112s.

 

[HiluxSurf SSR-G]

i thought there was only very minimal difference in extended lengths between the two? I read somewhere that the Tundra version has an extended length of 18.35" vs the 18.27" extended length of the 4Runner version
