Other than alignment issues ( which I never had) the d50 ttb is a strong axle.
I've been extremely impressed with mine. I've broken the tube on drivers side, but after a piece of 3/8 plate formed around the knuckle and pumpkin I doubt it will ever break again.
I snapped that a mile down a lake road, in a blizzard with a v-plow on the front and chains all way around and a yard of sand in back. I dumped the plow and (no kidding) drove the truck probably a little over 1/4 mile do my other truck and trailer could get to it.
Let's just say my most badass truck has a ttb d50 and I'm not scared one bit that it will let me down. Go to my YouTube account and see how bad I thrash my mud truck with a ttb d50. Like I said, other than alignment issues it's a great axle.
So keep the coils. I don't see why you can't.
Vans have coils on their 4x4 conversions. Just need to attach the coil buckets on the axle.
To get the height you want you either get longer coils (probably tricky to find 1ton rated lift coils maybe 2wd 1ton lift?) or drop the coil hoops lower on frame.
Not what I ment.
The 2wd coils may not lift the frame off the axle enough and the pumpkin may hit the crossmember or engine parts. The 2wd ttb beams are designed to take up less space so the big axle may need adjustment. So either get lift coils or drop the hoops til you get height you want.
Bumpstops are your friend.
Thanks for the advice and the links. Really helped out. Depending on what my donor truck has, i will probably ditch the coils. its a tight truck to start (built to tow our boat during the summer) so im not really worried about the comfort of the ride. All i need is a truck with good 6 wheel traction for working on the farm in the winters (and the occasional mud hole of course haha). Donor trucks im looking at in the area are an '87 F250 with IFS and a 460 or a '89 F350 with a 7.3 naturally aspired diesel and the straight axel.
Yamahabiker94:I went with leaf springs for durability and ruggedness. Coils are great, but when you plant a heavy load in the bed, and start traversing some farm land (dirt roads, pot holes, bar ditches) you can feel that the extra beef may be desired. For the same reasons as you have, is why I did mine. My CC Dually sucked on wet grass on a flat surface, and I do a ton of hauling and work with it, so I did not need a Wyoming winter creeping up and sinking the truck for the season!
Yeah I have the same reasoning for it. that and i work on a local ranch so all wheel traction is a must have in the winter. Our winters get rather nasty over here in nor cal. Infact we're expecting a nasty little snow storm tonight.
