TNGA-F Platform compatibility (1 Viewer)

[jay3253]

Is anyone interested in compiling a list of parts that are cross compatible with all vehicles with the same platform? I would be very interested in that anyone else?

Rear Springs: Tundra, Sequoia
Half Shafts: Tacoma (TRD halfs are much more beefy and have a greater angle of articulation.)
Upper A-arms: Tacoma.
Lower Control arms: Tundra and Sequoia.
Upper Control arms: Tacoma, Tundra and Sequoia.

Is no one interested in this?

It sounds like there are many parts from the Tacoma TRD PRO that we may be very interested in. The half shafts for one. Does the lower control arm fit the TLC? What about the upper? The rear springs on a Sequoia fit but what about the fronts? Those are just a few examples there have to be others.

When I purchased the OEM skid plates with the truck the accessory guy asked if I wanted “Toyota” “TRD” or “trailhunter” stamped in them. So I assume all of those are crossing over from Tacoma and probably 4R.

I'd love to see these details too. Have been trying to find details about those that have put on the Tundra/Sequoia rear springs and what they've done in the front.

Update: Tundra rear springs add a 1.5in lift and fit without modification. There is a video on YouTube showing the installation and results. I cannot find it again so if anyone sees it and is interested please post.

Interested in this as well.

Were the Tundra springs added with the stock rear shocks? What effect would this have on articulation and travel?

Most times you add lift to a live axle it will increase articulation and sometimes travel.

Rear shocks from the video I saw used the stock shocks.



A lift to the front independent suspension typically limits both travel and articulation.

Looks like King shocks in the video. Wondering if the larger springs would limit the down travel by overextending the stock shocks.

I didn't look too closely. I just know they fit. I would look at new shocks but they didn't say anything about that.

Logically if the springs do indeed create a lift, the stock shock is now extended more than stock in the resting position and downward travel would be limited by the same amount as the lift, assuming there is very little if any spare travel in the shock and dependent on sway bar setup.

Okay, but that only applies to the independent front suspension not the rear. Those limits are from the the shocks. Change the shocks most if not all travel back. The point it they fit, and if there was a front spring lift I'd get that too. I am only after about an inch and a half to offset a bumper, winch, tire carer and extended range tank.

Um, not to sound silly but the rear of the truck has a cylinder filled with oil that is used for dampening that spring in the rear. Commonly called a shock. That oil chamber has a piston and rod that has limited travel in either direction of its installed static state. When the rear of the car body is lifted away from the frame, by any means, the new static distance between the axle and the strut body mount is now greater and to achieve more travel needs a strut with more travel. The end of the piston is now nearer to its top out so it has less or no travel to drop. Im sure we can agree the shock does not indefinitely extend and we are addressing downward travel of the axle that is now further way from the body. In reading what you wrote, I now see you mention changing shocks too, but that was not the intent of the question I answered

Okay if you don't read my reply please don't respond.

I just want a post that brings together the information that the OP says. If you don't want to contribute then don't. If you do then do I'm not arguing with you, if that is what you want you are in the wrong place.

Thats fine and please remember that I did not respond to your post. I responded to your response to me. And your post to me was poorly written so it does not read well and to the point. Im not arguing by stating facts. If I am wrong, Please educate me. Im interested in learning. In the instance of bringing info together, its important that someone reading the thread understands if non stock springs require non stock shocks to bring the performance. That there was one question asked means many more are out there. All good though. Good luck on the internet and sorry to ruin your multicar platform transformers thread.

Okay, so the upper A-arms are interchangeable with the new Tacoma. The lower control arms are compatible with the Tundra and Sequoia. The upper rear control arms are compatible with the Tacoma, Tundra and Sequoia. I'll keep looking for others as they come out. I want to know about the lower A-arms and the half-shafts of the Tacoma TRD Pro. Those are much beefier.

Spring compatibility is pretty universal among Toyota rear coil solid axle setups. They've been basically unchanged for 30 years and nothing looks new here. Just need the OEM effective spring rate and free height and you can figure out what lift you'll get from any of the other combinations. Lifting the rear more than maybe 1" should be done along with longer shocks and extended bump stops.

I'm curious how the Tundra air suspension will work in the LC250 and other GA-F models. I ran GX460 air suspension in my 5th gen 4R for a while. Springs were great, issue was shock valving was hard to match up to the super progressive spring rate of air springs with most aftermarket shocks being designed around roughly linear rate coil springs. I think they only come with AVS, so you'd probably run into the same issues I did. The air springs visually look nearly identical to the GX460 springs. I think they'd probably match up best with the AVS 4Runners, but not sure about how they'd work for the LC250 unless you can sort out the shock valving issue to get a great ride.

Any idea if the 4Runner Trailhunter suspension might fit the Land Cruiser?
