Finally found a graphic of the Dexter Torflex Arm with varying start arm angles. The Dexter 3500 lb axle's default start angle is 10° positive ( that's the angle on the TM axles). I was trying to determine if there would be sufficient clearance to switch from a 14" 5 on 4 1/2" 'wheel to a 15" 5 on 4 1/2" wheel without a riser kit. Unfortunately there is only 3" of wheel well clearance as it is and that's with the torflex arm at the loaded angle. At the shock angle the 15" tire would be at or very near rubbing the top of the WW. Dexter recommends a 3" bump clearance, so it's not to be. On to plan B.
