OHV Reinforced

ProMaster Axle

Why do I need the OHV Reinforced ProMaster Axle?


RAM ProMasters are an excellent choice when it comes to building a custom van. They are spacious and often less expensive than their Sprinter competitors. Unfortunately, these vehicles are not designed for all-terrain conditions. ProMasters are built to drive on smooth paved roads and come with limited suspension performance. Taking Promasters off-road can leave suspension components vulnerable to damage and failure, but thanks to our innovative team of engineers, OHV is prepared to install more durable and long-lasting parts specifically designed for the RAM Promaster. 


One particularly vulnerable component on RAM Promaster suspensions are the front axles. Located just behind the wheels, the axle’s job is to transfer power from the engine while simultaneously allowing the wheels to maneuver and adjust to varying terrain. This makes them a critical part of the suspension system. Rocky and bumpy roads demand higher performance components that are built to handle the rough terrain. To reduce the risk of axle damage, OHV is now offering its own custom front axle to help prepare your van for even more adventures. 


How Does it Work?  


Promaster stock axles come with what are called plunger joints, which act like knees and elbows in the human body. As the vehicle encounters different terrains, these joints respond by flexing the arms of the axle thus allowing wheels to raise and lower. Roads that are not smoothly paved can easily over-stress these standard joints which can result in vehicle immobility, turning your van into... well, just a house. Obviously, if you are exploring unmapped territory, this might not be ideal. The fact is, true adventure vehicles require more durable parts for rougher terrain. 


OHV Reinforced ProMaster Axles are designed to eliminate that risk by replacing these weaker plunger joints with a slider mechanism. This design behaves similarly to a shock which gives the axles greater absorption and flexibility over rough terrain, resulting in a more dependable suspension system. Additionally, the front axle is designed to complement the OHV Promaster Lift Kit. The two parts work together to produce greater ProMaster clearance and increased peace of mind for owners looking to take their rig off-road as soon as possible. 


Go Anywhere


OHV Reinforced Promaster Axles are guaranteed to enhance your Promaster’s off-road performance. Our experienced team is familiar with the challenges and risks associated with Promaster conversions and has created parts designed to triumph. As you push the limits of your van, Off Highway Van will be there with parts enabling you go further.

Frequently Asked Questions

Does this installation void my vans factory warranty?

The best answer might be, it depends. Dealerships will take after market parts into consideration but have also been very flexible with many of our customers. Sometimes it varies by dealership.

Will there be any additional maintenance?

No, but we do recommend getting things like the CV boots and surrounding components checked regularly, especially if you take your ProMaster on rough terrain frequently.

Can I have the axles installed locally rather than driving out to Utah to have it installed by Off Highway Van?

At this time, Off Highway Van is the only shop capable of doing a professional install. We know it can be a big time commitment to travel to our shop but we are doing our best to make this installation available in other locations. Until then, come see us, we are a lot cooler in person.
