Painless Wiring Parts and Accessories

When you are tearing up the trail, you rely on your rig's internal systems and off-road accessories to function perfectly. Nonetheless, if your vehicle doesn't have access to a steady supply of electricity, you may find yourself stranded somewhere you would rather not be. At 4 Wheel Parts, we have the Painless Performance Products you need to take your off-road adventure to the next level.

Rewire Your Rig's Electrical System
If you drive a vintage truck, Jeep or SUV, your vehicle's stock wiring system may not have the output or efficiency it needs to power modern electrical devices. Rewiring your vehicle isn't a tough job if you use the right equipment and parts. With a Painless wiring fuse box and circuitry, you get updated electrical output in your older vehicle.

Invest in a Master Power Disconnector
As an off-road fanatic, you rely on your rig to deliver an exceptional experience. As such, you have several accessories you use when you are on the trail. Of course, your electrical components can be a tremendous drain on your 4X4's battery. With a Painless wiring master power disconnector, you can kill your rig's electrical output when you don't need it. For extreme off-roaders, choosing the right Painless wiring accessories can be tricky, however. If you need some help, chat with one of our parts experts. We are always available to help you choose the perfect Painless wire solutions for your vehicle.
