yes tubbing,

making big tires fit under those skinny fender's.
let's try this again!! any one try this yet on your 47to 54 chev trk. if so ,let me know

We have done several but be warned--it's not a weekend job. You can get rear glass fenders that are 2 to 3 inches wider and that will allow a ten inch tire which, in the right compound, can handle 400 t0 450hp. This is of course with the suspension to go along with them. For the tubs you will have to cut the frame and move the rails inward the amount that will accomodate the tire width you want. You can use either ladder bars with a pannard rod or the 4 link, but in either case use coilover springs because space is at a premium. Depending on how narrow you go you will have to choose a spring rate that will give rear stability with the narrower track. Mount the coilovers as near verticle as possible and as low on the axle housing so you get the true rating of the spring and a lower roll center. No vehicle with a super narrow rear track and soft sidewall tires is worth a flip in the corners.

hey evan thanks for the info i was wondering if you ever used air ride shocks in this application.

For a truck box I've seen vendors carry fiberglass wheel tubs that bolt into the inside of your box they look pretty good when installed and let you keep the outside of the truck look stock but allow you to run wider tires. If I remeber correctly Jim Carters carries them.

Be aware that on the AD trucks the bed side is right against the frame so even if you put a tub to the inside--the frame is still there in the way. Yes, we have used air ride shocks and they can be mounted in a confined space. They do require an onboard pump, valving, and lines. This is fine if your adjusting the height and rate often but, the springs on coilovers can be replaced with little time or labor, cost about $100 a pair, and are stand alone units.
