For many off-road drivers, tweaking components of the engine, exhaust and other vehicle systems are all part of the fun. Tires with wider treads, swapping out differential gears and lifting the body are just a few of a seemingly endless number of modifications you can make to your truck or Jeep. Sometimes, the result you're after is better performance, sometimes you're just making a repair, and then there are times when you're making a change just because it looks cool. Whatever your reason, 4 Wheel Parts wants to help. We've gathered essential pieces for an AMC 360 serpentine belt conversion, for example, along with crankshaft pulleys, dampers and more for you to use in upgrading vital crankshaft operations.

Essential Pieces to Replace or Upgrade
Trusted manufacturers such as Jet Performance, Crown Automotive and Mr. Gasket Company offer several items to help you keep your truck or Jeep in top four-wheeling form. You'll find a crankshaft pulley wheel, vibration damper and an underdrive pulley set here to replace worn parts or upgrade system components. Underdrive pulleys can help boost horsepower and mileage by easing the drag on the engine from power steering, air conditioning and other accessories. Replacing a worn or damaged damper is crucial to smooth engine performance and to prevent further damage. Essential parts like these and accessories to make your life easier are what you'll find at 4wheelparts.com.
