lol so weak chasis, or strong IFS. I'd go with the chasis, i dont like flexy trucks =).

Can you link some of the places you found pics.

Thanks... <img src="/forums/images/graemlins/patriot.gif" alt="" />

It doesn't. They are all C-channel. From '95 -'05

My 95 is not C channel. Its boxed...

Mines boxed too, I checked after i saw it on this forum =D. Also checked my friends double cab tundra, its three wall. I was pretty shocked to see it was boxed, i thought boxed ones only came on newer trucks.

All 95 and later Tacomas are C-channel. Not sure if you guys know the diffrence between C-channel or not. A fully boxed frame, as in the pre- 95 trucks, is a rectangular box without a seam. A C-channel frame is a rectangular box, but there is an overlap where the two sides meet, and it got welded there. The whole Tacoma frame is like this upto the rear-end where the frame opens up. These C-channel frames are supposedly not as strong, but they do flex better. I'm not sure if it's beter to have a fullbox frame that is stronger, but don't flex that well, or if it is better to have one that flexes. I wheel my C-channeled Taco moderately hard, and have had no problems.

I see, very intersting. What is the one that only has three sides (i.e. new tacoma and tundras)?

All Tacomas have C-channel frames with the rear end of the frame having three sides, i.e. an open(or three walled) frame. All you need to do is look alittle farther forward, and you'd see the seam on the rectangular box that I reffered to. The new 05 Taco's front end (front 1/5 th of the frame) is actually fully boxed, i.e. it is a seamless weld. For more info, check this: http://www.4x4wire.com/forums/showf...&o=&fpart=1&vc=1

It took me a while to find anything definate about types of frames but here goes my shot.

"The Titan has a fully boxed ladder frame with closed-section side rails rather than the traditional C-channel open section rails used in most full-size trucks. Ford has also started using this type of frame for their F-Series trucks." -About.com

There are different types of fully-boxed frames be it hydroformed, seemless, welded, but they are all fully boxed as compared to U (on older jeeps) or C channel frames. The way in which it is fully boxed doesn't matter, other then it is boxed. Of course each process has their advantages, but a C frame is an open channel.

At http://www.truckworld.com/Truck-Tests/04_f150_first_drive/04_f150.html (Truckworld Magazine), they describe the F-150 as a welded/fully boxed frame. In my search for seamless fully boxed frames for F-150's there were no results.

Also, Rick Titus's F-150 bit on the ford website shows how the Tundra's frame deflects 6.something inches while the ford fully boxed does 0.5 inch on video, thats pretty neat. Ford's is definatly not a seamless boxed frame, but it is still a boxed frame.

As for the entire lenght of the tacos, im not sure if its fully boxed the whole way back but its good to know that a big part is.

(Yes I have too much time)
