Lift options with existing Toyota TRD 13-35140 kit?

[Sanpete]

Hi guys. 2018 TRD Off-road premium. I got on that deal back in early 2018 where Toyota was clearancing the FJ/4R PRO Bilstein suspension (TOYOTA part 13-35140) as seen in this big thread:

https://www.toyota-4runner.org/5th-...rd-pro-suspension-kit-sale-ptr13-35140-a.html

It's basically a 6112/5160 setup. Love the setup, rides great.
BUT.
This kit only adds ~1 inch up front.
I want ~2-3" of lift, overall, front and rear.

Question is: Can I simply add taller and/or heavier duty springs to the existing shocks?
I'd prefer to keep the existing shocks and simply replace springs to get the extra height. Or any other suggestions to maintain these shocks but get more height?

Tires are 255/75/R17 Goodyear Duratrac's on the 17x7" TRD Pro wheels.

why not just get spacers. They install on top of the springs (front and rear) and add 2-3" front and 1" rear. They are very inexpensive (About $120) and fairly easy to install.

I put Rough Country spacers in my 2018 SR5 premium and love them. They don't change the ride. There are many others that make spacers.

Why the 255 tires, or is that a typo? The 2018 SR5 and TRD pro came with 265 tires. You will loose a small amount of high with the smaller tires.

I have to agree with him most people go with spacers for just the 1' lift but if you are going to add winch or bumper you need springs for added weight
255/75/17 is this because you want that wider stance, I have the Duratrac in 265/70/17 and they are awesome

I bought the same kit shortly after buying my 4Rrunner in 2018 but I still haven’t installed it yet.

Most people who run 255s (including myself) use a 255/80/17 which is a TRUE 33" unlike 285/70s (~32.8). They are called pizza cutters - mine measure out at 33.1"h x 10.0"w new. Biggest benefits are nominal to no decrease in driveability with larger tires.


Back to the shocks - I believe Dobinsons and Eibach have a front lift coil for these shocks, if you don't want to run spacers, everyone will have an opinion on them.

Caveat - those were FJ specific suspension for the fronts. They utilized a 14" coil. The 4runner specific versions used a 13" coil, which would benefit from a taller spring such as a 14" coil.

You can swap in other 14" coils but you'd only get a lift by increase the spring rate - not recommended unless you're added weight. I don't think installing 16" coils is a good idea btw - not sure if 15" coils are common.

If you had 4Runner Pro suspension, you'd be able to throw in a 14" coil and get a 1"+ lift with the fronts. This is what I did with my suspension (which is now in the for sale section).

Because you're adding pre-load and reducing the travel capacity of the front suspension.

hey [MENTION=411635]Sundy[/MENTION] can you run 255/80/17 on a runner that is lifted only 1" on Trd Pro rims or will you have rubbing issues and need to do some trimming

You should be okay, might have a small amount of rubbing on the front liner (you can trim or just move forward) and possibly a small amount on the mudflap. [MENTION=125682]RedRunner_87[/MENTION] ran the 255/80R17's on a fully stock SR5 for awhile. He had some rubbing but I believe was driveable? I've got another friend with them on his stock TRD OR and he just has minor rubbing on the front fender liner/bumper liner.

I only had rubbing on the front mud flap without a lift. Just remember that the TRD Pro wheels have a different offset than the SR5/TRD OR wheels. Even stock the Pro gets a bumper notch to get rid of rubbing. I rubbed like crazy on the front bumper with 1.25" spacers. So I would count on at least doing the bumper fender liner mod with the TRD Pro wheels.

255 is width not the height. There is many advantages of skinner tires on and off-road.

Less rotating mass- Easier to start and stop
Less reciprocating mass- Easier to dampen
Less wind resistance- Better economy and range
Less rolling resistance- Better economy and range
Easier to fit a taller/narrower tire with less lift
Lighter spare
Lighter tire
Lighter wheel
Less unsprung weight
Less weight and leverage on steering components, bearings, etc.


Less frontal resistance in mud and sand. Where is most of the increased contact patch (for flotation) gained? In the length, not the width. Tall and narrow allows for more length and greater deformation with less resistance.

Yes, all those reasons. I switched from a heavy KM3 in 265/70 to a taller, narrower 255/75 Duratrac and lost 15 lbs per tire. That's 60 lbs all around, unsprung mass. Both me and wife can feel the difference.

OP here. 255/75's on the TRD Pro wheels, and I'm rubbing in the front, on the bumper edge. Hence the desire to lift a little (will be trimming too).

If you want more lift sell the TRD suspension you got and get aftermarket.

Spacers is not the way to go makes the ride crap. Anyone that tells you otherwise is high. But if you want cheap and don't care go for the spacers.
