Matt- my EB w/36x12.5's on 3" bs rub a little so I'm going to guess with 14.5's and 3.5" bs you're get a lot of rub. You might try welding a 1/2 piece of tubing on the arm at the spot the tire hits. I've seen it done and it worked very well;)

I wish I had a pic, maybe someone else can post one. It's a pretty common mod.

Good luck!

But what about the wider F150 axle? Isnt there more clearance from the arm to the WMS on a full width axle???

Thanks for the specs
Doh! Damn, I didn't even think about that, but you're right. I'll measure mine from the arm to the knuckle weld tonight and give you the spec. That should give you a frame of reference to work from;)

I am running an EB axle with 3.75" BS wheels and 1 3/4" Spacers... basically 2" BS wheels... with 24.50 SX's... no rubbing, but pretty close. I think when I am aired down and flexed out on the trail I may rub a little.

I run 37x12.50x15 and I built my arms with a 27* bend in right were the tire would hit and I have 1"+ before hitting and still get stock full turn out of it.

No, the f150 frame is much wider than the eb so you end up with about the same distance from the c-bush to the wms. That's one of the advantages of the earlier housings with weld on/moveable C's . If you can make frame mounts on your heep as narrow as the eb then you coulds switch your guts to one of these housings & move the C's in. You could gain a little by just building your frame mounts narrower and forcing the arms in. You won't lose that much flex but may end up eating the frame dounuts more quickly. BTDT
