We all feel that need now and again. Those times when we slam down the skinny pedal in hopes that our fully equipped 4x4 will blast past the surrounding traffic and wail down the road like a performance sports car. But face it: It's a 4x4. What can you expect from 35-inch tires and low gears? After the initial resolve that your stout rig just doesn't offer what it takes to bypass even the shabbiest of passenger cars (let alone enough torque to edge over the skimpiest of obstacles), you might consider the many options available from the aftermarket designed to create more power where it's needed. A number of supercharger systems exist to effectively improve your vehicle's performance. The following compilation of manufacturers represents the lion's share of what's offered to better equip your rig for the street or trail. Check it out. You may just discover the right recipe to feed your needs and your vehicle's power-hungry appetite.
