Dexter will send you a Torflex axle order worksheet to help you order, and customize, an axle. Their phone number is (574) 295-1900. Fax number is (574) 295-8094. If you call and ask, they'll send you a customized cost and engineering estimate they call a
"Prospect." I asked for one today and the guy who is doing it was very helpful. 8/07 follow up...I highly recommend you ask for a Prospect so you can get your axle customized to your needs.
The main categories on Dexter's Torflex axle order form are:
Axle Capacity (load weight, it can be customized)
Hub Face
Outside Bracket
Brakes (optional)
Spindle Type (lubrication options) and whether you want the standard spindle or the short one which is 1/2" shorter.
Bolt Pattern
Start Angle
Bracket Orientation (inward or outward facing & low or high profile)
Attaching Parts Kit (optional, with it the axle is bolted to the attachment kit, instead of welding the axle onto the frame)
On Dexter's website
http://www.dexteraxle.com/our_locations you can find the location, and phone number, of the Dexter plant closest to you. By ordering from the nearest one you may lower your shipping cost. I was told to expect 2-3 weeks shipping time after an order.
They'll customize the rubber on a Torflex axle to match the load weight capacity you need, at no extra cost. Doing so, I was told, will make the ride less stiff
If you order the optional Attaching Parts Kit it can be welded to your frame instead of welding the axle to the frame. The axle is then bolted to the Attaching plate. In the future if you needed to remove the axle you wouldn't have to cut through welds.
