I recently found a 78 f150 with a full width dana 44 and 9" rear for a fairly decent deal. In the midst of researching this deal and upgrades I stumbled across a company called RCV. They make birfield type CV style axles. I learned they also make custom axles. So, just because I wonder just how far a TTB axle can be taken, I asked about a set of custom axles. This is the reply I received: Hi Chris, We are actually just in the prototyping phase of a totally CV based TTB system. We expect to be shipping over the next 30-60 days. The price is $1,995.00 a set and it comes with our limited lifetime warranty against breakage. Give us a call if you would like to place a pre-order to ensure you get a set. Thanks! Original message: Hello. I was wondering if you make custom axles? I know this is a long shot, but I have been wanting to do something different. I have a 1991 Ford Explorer with the TTB Ibeam front suspension. The front axle is a dana 35. I have made some suspension mods (lift) and axle upgrades (lockers, hubs and soon gears), however, axle mods are extremely limited. Thus my question. Sorry for the lengthy explanation. Thanks for your time. Just some food for thought or maybe a conversation starter. What do yall think?
