4.0 Coilovers For Our Super Duty Support Truck
It's no secret that we beat our trucks. Most of them see more re placement and aftermarket parts than six trucks, but luckily we are constantly able to try out new parts to replace the stuff we beat on. after five years, our fiberglass-laden Super Duty is still looking pretty good, but its purpose has been somewhat mixed over the years. It's seen its way to Moab, Utah, been driven as a highway cruiser, mobbed through deep mud, and prerun through roads so rough you wouldn't want to take an IFS truck through them. needless to say, Super Dutys do not have the most supple suspensions known to man, and if we wanted to use ours as a giant chase and support truck, some changes would have to be made.

The body was already taken care of, with hannemann fiberglass fenders and bedsides coated in an L&G Customs paintjob offering coverage from debris flying off the tires. The interior was set to go (with the exception of a rollcage) with MasterCraft Baja RS seats in front, a MasterCraft bench in back, and a full Sony system with flip-down monitors. The crew cab configuration offered a ton of room for hauling gear and people, and after all these years, we finally got our truck down to Executint in Mission Viejo, California, to tint the windows and keep the cab from displaying us like a giant aquarium.
We still have to install some stout bump-ers capable of taking severe blows, add a winch, make some provisions in the bed for equipment, and build a rollcage, but for now we wanted to turn our attention to the suspension and tires to try to squeak out a better ride from our mammoth piece of metal.
Since the truck had been residing in utah over the last couple of years, we were going to have some serious seat time driving it back to the Southwest, and we wanted to use the opportunity to feel out a new coilover suspension capable of handling desert abuse while still being able to hold up a diesel. the skilled hands at Mount logan off-road offered to help install a fabtech 4.0 Dirt logic coilover conversion kit before the truck left the state, enabling us to get used to the 8-inch height and new 41-inch radial iroks all the way back to California. now we know what you're thinking: 41-inch tires for a support truck?! When our publisher told us what size he'd ordered for us, they sounded a little large to us as well. But we have to say that we've been very impressed with the way they've held up to freeway driving, dirt rallying, and how "normal" they look in our fiberglass wheelwells. overall, this package really performs, with the Dirt logic coilovers offering a substantial amount of shock dampening for such a heavy truck. one thing we have learned is that it's imperative to keep a close eye on air pressure with tires this big. if one is low, the amount of slop available in the sidewall is much more than you'd ever want to deal with at high speeds.
