Hedman Street Headers

For the price, no other part can give you the horsepower and fuel economy improvements of Hedman headers. They make Hedman Street headers so well that they guarantee them to be free from defects--including cracks in the tubes and welds--for the life of the headers. Hedman Street headers are available uncoated or in Black Maxx or their polished HTC thermal ceramic coated finishes and, as an added bonus, they also come with all necessary gaskets and mounting hardware. Unless otherwise noted, these headers are designed to fit the vehicle as it came from the manufacturer. This includes components like cylinder heads, chassis, steering, motor mounts, body mounts, and bushings, etc. If your vehicle is using aftermarket components, parts from other applications, or custom-altered parts, then it is the installer's responsibility to verify fitment. Special warning regarding Hedman painted headers only. The paint on these headers is not designed as a final finish; it is designed to protect the headers after the manufacturing process and during shipping. This paint will not withstand the high heat associated with engine break-in, nor will it withstand the heat cycles associated with any type of driving. It is recommended that this protective coating be stripped, and a high heat paint or coating designed for use on headers be applied.

BMR Xtreme Anti-Roll Bars

BMR Xtreme anti-roll bars feature a massive diameter and include heavy-duty rod ends. These sway bars have an easy bolt-on design with the option to be welded, if desired. The factory rear sway bar works well for handling, but falls short when it comes to drag racing. There are two main reasons for this—the OE bar diameters are nowhere near the right diameter to control torque loading on a launch, and the OE-type bar only attaches at the control arms with no frame attachment points. This allows for too much body separation and no way to control it. By attaching the end links to the frame, body separation is minimized and converted into forward momentum. This, combined with the large diameter bar's ability to better control torque loading, creates more consistent and predictable launches and better 60 ft. times. BMR Xtreme anti-roll bars come with all necessary Grade 8 mounting hardware.
