Ultimate Super Dirty Gets Some Energy Suspension Upgrades

There’s nothing quite like an overbuilt project truck with some hard miles underneath it. If you’ve ever built or modified a truck to play hard in the dirt, you’re probably well aware that some factory suspension components just aren’t meant to survive all that long. Our 2013 Ford F-250 Project Ultimate Super Dirty has seen its fair share of hard off-road miles from multiple wheeling trips as well as the 2013 Ultimate Adventure.

While this truck was built to handle the gnarliest terrain imaginable, we knew it was probably about time to get our former UA beast up on a lift to inspect all the steering and suspension components for wear and tear that could potentially leave us stranded on a trail.

We traveled out to Energy Suspension’s facilities in San Clemente, California to see what parts we’d managed to abuse over last year. As it turns out, we had a few components that were too far gone or about ready to give up the ghost. Luckily, Energy Suspension stocks complete kits for most factory vehicles so finding replacement parts shouldn’t be a problem in most cases. Although Energy Suspension has kits available for the Ford Super Duty up through 2007, they would have to piece together parts from all across their catalog for our highly modified Project Super Dirty.

Our front O.E. bump stops were pretty useless and showing signs of wear on the primary impact surfaces. That’s not all though, the foam material was beginning to dry out and deteriorate. Fortunately for us, Energy Suspension had us covered and quickly removed the tired O.E. bump stops and replaced them with a set of their Ford Excursion Rear Axle Bump Stops (Kit #9.9155). These polyurethane bump stops are heavy duty for living in harsh environments and provide a more predictable impact surface while maintaining the same compression/hardness as the O.E. bump stop.

Because of how Project Ultimate Super Dirty gets used, Energy Suspension wasn’t satisfied with the factory “snap-in” mounting style so they went ahead and drilled and tapped a hole through the top of the mounting location and into the frame in order to ensure that the bump stops stayed in place even when fully compressing the suspension on the trail. They also had to modify the bump stop to make it fit our application as they are not meant for a Super Duty.

Out back, our rear O.E. bump stops were worn out much the same as the front bump stops, but we were able to replace them with a set of Energy Suspension Ford Excursion Rear Axle Bump Stops (Kit #9.9155) which bolted right in place of the originals with no modifications needed.

Back up front, the O.E rubber bushing at the frame location of the track bar was showing signs of wear and additional stress which is typical on lifted vehicles with larger than stock tires. In order to keep the track bar from binding or experiencing additional torsional stress, we replaced the O.E. bushing with one of Energy Suspension’s replacement front track arm bushings (kit# 4.7131).

This bushing and sleeve combination provides more strength, a larger wear surface as well as better isolating abilities than the O.E. bushing. Like the polyurethane bump stops, it is also resistant to road contaminants so it will not degrade when it comes into contact with oil, road salt, or other chemicals.

We were absolutely impressed by what Energy Suspension did on the Heim joint end of the track bar. They installed one of their first sets of Heim dust boot prototypes. These boots help protect the articulating metal components of the Heim joint from dirt, rocks, and other substances while still allowing the joint to flex freely and best of all is we’ve got some cool trick parts to drool over when we’re not out wheeling our Project Ultimate Super Dirty!
