Mr. Gasket Header Bolts

Installing headers can sometimes be a real pain, due to the tight spaces and the location and shape of the tubes. Mr. Gasket can help make installation a little easier and also help prevent annoying exhaust leaks from under-tightened header bolts. They have both the socket-head and hex-head styles of header bolts available. Hex types are heat-treated Grade 5 steel and have smaller-than-standard heads to ease access in tight spaces. Socket-head bolts are made from stronger Grade 8 steel for added ruggedness and they're great for those really difficult-to-reach spots. Both styles have a protective black oxide finish.

WeatherTech Underliners

Most pickup trucks don't come with bed liners from the factory. If you plan on adding drop-in liners, look no further than WeatherTech new Underliners. Drop-in liners are rather rigid and tend to slide back and forth against the truck bed—causing scratches in the paint, trapping water, and, if unprotected, allowing rust. Conversely, WeatherTech Underliners provide tight, digitally designed fitment to the contours of the bed. Their .064 in. semi-soft thermoplastic construction helps keep your cargo area safe from both the elements and freight you're hauling. With the cost of trucks at an all-time high, the last thing you want is to aid in its deterioration. Keep your truck bed looking new with WeatherTech Underliners.
