Obviously, comparing off-road capability between the boxy 3/4-ton 2017 F250 and the agile F150 isn't really fair - we appreciate the respective pickups for very different reasons. However, equipping our 6,000+ pound Super Duty with the BDS 4" Radius Arm Lift undoubtedly helped to even the playing field. Even in 18-24 inches of powder, our biggest project truck never let us down.
Our mighty F250, looking far cleaner than it would by the end of the day.
Let's address street ride with the 4" BDS Radius Arm Kit - it's great. Simply great. The mostly-highway trip up north was smooth, accurate and comfortable. 35-inch tires leave plenty of clearance and we've experienced virtually no rubbing since install. While we didn't throw on a complete radius arm lift with upgraded Fox shocks just to enjoy a supple street ride, we were more than pleased to find out that OE ride quality and handling were fully retained.
Now on to the fun stuff. The 4" BDS kit, buffered by the available Fox 2.0 upgrades, handily dispatched the various ruts and bumps we smoothed over during multiple runs through the snow-covered cinder hills. The included heavy-duty radius arms are constructed from 1-3/4" OD -10GA DOM tubing with support gussets, which proved useful for maintaining stability in those moments where our tires weren't sure which direction they wanted to go.
At the end of the day, our mighty F250 was able to triumphantly return to the friendly washboard roads without needing recovery assistance once, which unfortunately is more than we can say for a few of the other project trucks that went up with us that weekend. With the BDS 4" Radius Arm Lift Kit and upgraded Fox 2.0 shocks, we think we've finally settled on a long-term suspension setup for our 2017 F250 project truck. Off-road capability is about as impressive as it gets and OE street ride remains untouched. If you're looking for versatility, look no further. Four inches still not enough?
