Superlift's 6-Inch Super Duty Kit
When you're putting together a "usable" truck that can act as a work truck, chase truck, tow truck, and full-on support truck, you need to make sure you put a functional suspension that isn't too high or too stiff. Using off-the-shelf parts is always a big plus, so replacement parts can be ordered and shipped directly to you should the need ever arise. Our friend Mike O'Donnell had his truck up on 38-inch Cepeks with an entire set of expensive custom leaves and dual remote-reservoir shocks. His truck had around an 8- or 9-inch lift and was just a bit too tall to be really useful off-road or for work. The 38-inch tires were verging on being a bit big as well, but if we could drop the truck down in height and still keep the same tire, it would be a lot more functional. At the same time, we were curious at how an off-the-shelf kit would perform against a fully custom megabucks kit. To make the challenge a bit more fair, we called up Superlift and made sure we got every option we could with its off-the-shelf 6-inch kit. And even with the Superlift kit all opted out, we were still not at half the price of the four custom leaves and remote-reservoir shocks O'Donnell had on his truck previously. Xtreme Unlimited in Oceano, California, removed the original suspension and installed the new suspension. We then headed to Oceano (Pismo) Dunes for some suspension testing. It was great having Xtreme Unlimited's shop only a few miles from the sand dunes in case we overtested something.
What Did We Think?
Seriously, Superlift has really set itself on a top tier in our minds. This is not the first time that we have seen a Superlift suspension best a suspension costing many times more, but it is hard to believe that some readily available parts that could be ordered in just a few days could work as well as custom-built shocks and leaves, much less better! But Superlift really did a great job matching its shock valving to its spring rates. The Super Duty kit really smoothed out some serious bumps while keeping an amazing on-road ride quality. Any classic Super Duty chatter was gone, and there was no nose-bobbing. The Torque Max traction bars worked in unison with the rear leaf springs, still allowing a ton of movement while inhibiting any axlewrap. We ditched the rear antisway bar when we added the rear Superlift kit, but O'Donnell is thinking of putting it back on now that the rear has a more supple rear suspension.Sand-dune play is a great way to test if your tires are going to rub anywhere. The 38-inch Mud Country tires were still rubbing a little bit on the front fender during full compression, so we'll either have to cut more fender or add fiberglass fenders to the truck.
