If the off-roading you're doing is limited to fairly well-maintained roads, then the Bilstein 5100s would probably be the more cost-effective choice. If the roads are fairly rough, then either the Fox or the Halo Lifts coilovers would probably be your best bet. The Fox coilovers only go up to 2" of leveling, and that's where they're usually set out of the box. The Halo lifts coilovers are capable of going up to 3" of height, and are usually set at around 2.75" of height out of the box. Neither the Fox nor Halo lifts coilovers are particularly stiff at 2" of height (especially considering that the Halo Lifts coilovers need to be cranked down to hit that height). The Bilstein 5100s can be a little stiff at their 2.10" maximum ride height, but it's far from unbearable. Either an add-a-leaf or a 3" rear block will get you the same amount of ride height, but the add-a-leaf kit adds capacity at some expense of stiffness. Your best bet would be to call us directly at 623-434-5277 so we can get more specific about your truck and what kind of stance you're looking for.
