Hedman Hedders was the first manufacturer to introduce advanced aerospace technology to the hedder industry. The alloy of ceramic-metallic composition used by Hedman, now known as HTC (Hi-Tech Coating), was and still is considered the very best thermal coating available for your hedders. HTC is bonded to your hedders with a strength factor exceeding 10,000 PSI. This durability makes the finish resistant to abrasion and chipping. Oil and grease stains can be removed with polish or fine steel wool. HEDMAN'S HTC COATING IS GUARANTEED against external rust-through for a FULL 5 YEARS. Together with Hedman's Lifetime guarantee against defects in workmanship, you will have years of worry-free hedder ownership.
Hedman's ELITE Hedders have more to them. The 3/8 in. flanges and THERMAL coat 14g tubing withstand full-throttle thrashing and torturous towing to protect against burnout and exhaust leaks caused by the excessive heat and vibration present in high performance and towing applications. ELITE Hedders outlast and outperform ordinary hedders.
Underdrive Pulleys reclaim lost horsepower and mileage by reducing the drag placed on the engine to drive the accessories such as the air conditioning, power steering and water pump. Installation consists of simple bolt-on replacement of the stock pulleys.
