Anyone tubbed an M2/FL cab to fit high base air seats?

Deezl Smoke · February 1, 2021

I have doubts that it has been done, but just in case, has anyone cut the riser out of the cab where the seats mount, tubbed it, and relocated the cab mounts so high base (standard) seats can be put in?

I see several have cut the back out to allow crawl/walk through to a sleeper. But so far, nothing about removing that vocational equipment rise and putting in a new flat floor.

Will a low rise seat base work? I know that there's M2's with air ride seats.

Yes. My FL70s have factory air driver side seats, I believe called "low base" seats. They're actually an ok seat. But nothing like what is in my Peterbilt. Since I will need to put an air ride passenger side seat in, and they're near the same price, I wondered if anyone had done the cab mod to accommodate the standard seat base. Kind of a lot of work on an old truck for the purpose, but we each have our own priorities as for what we want out of a rig.

Gotcha. Just remember, the seat and base are two different parts. The seat has more bearing on the comfort level, but the low rider bases do only have "so much" travel. All bases also have pivot points that use lube. Our seats smartened up immensely when I sprayed all the pivots with Brak-Kleen and lubed them.

Good points. Notes taken. I think we can get by with the low base travel and fewer knobs to play with, we just need to do as you mention, and make the shorter travel as posh as possible.

One thing I don't like about the low bases. I'm a long legged drink of water, and unless I can kick my legs out in front of me, a'la sedan, I look like a kangaroo sitting there. KW and Pete cabs let me stretch a bit, but I'd still like more. Nephew has a W900 with the seat on the floor. I hate it. He's about 5'4", so it works for him.

I'm only 5'11", but I too need my legs out front of me. My Peterbilt 379 is fine for my body, but the old FLD120 condo I had was even better, like your T2000. We do stop a lot on our travels. But I prefer to stop when we want to, not need to because our legs are cramping or backs are having spasms.

I have a plasma table and press brake etc., so I can do the work myself, but I like to see if what I plan has been done before or not. What lubricant did you use after you cleaned the pivots on your seats? White grease or something like slick50?
