AMP Research PowerStep Now Available For 2011 Chevrolet Silverado HD and GMC Sierra HD Diesel

AMP Research is pleased to announce a new PowerStep application specifically for the 2011 Chevrolet Silverado HD and GMC Sierra HD pickups equipped with GM’s Duramax diesel engine. This all-new PowerStep design has been engineered to work with the Diesel Exhaust Fluid (DEF) tank that is now standard on all GM diesel-powered pickups starting with model year 2011. Because these powerhouse trucks have been totally redefined with improved horsepower, torque and towing capacity, timing could not be better for the availability of the AMP Research PowerStep.

AMP’s highly popular PowerStep line of power-retractable running boards automatically extend and lower whenever a door is opened and safely retract, under the rocker panel, when the doors close. With a weight rating of 600 lb. per side, plus anti-pinch technology designed to prevent the step from moving if resistance is encountered while in motion, the PowerStep is ingeniously engineered to be remarkably convenient, durable and trouble-free. And low-profile, integrated LED lights come standard.

Each AMP Research PowerStep kit boasts die-cast, high-strength aluminum alloy linkage arms that are both anodized and Teflon® coated, plus precision, zero-maintenance stainless-steel pivot pins. It also includes everything required to ensure an easy installation, including all mounting hardware, complete wiring harnesses, an electronic control unit and vehicle-specific installation instructions.

The AMP Research PowerStep is made in the USA meeting stringent quality and craftsmanship standards and is backed by an industry-leading 5-year/60,000-mile warranty.

Another first from the craftsmen at Mark 7 Radiators! Using their downloadable specification sheet, you can precisely build a custom made radiator for your GM A-body or any other brand car or truck. Mark 7 Radiators are all custom units, never generic off the shelf radiators. They are available in natural aluminum, polished or anodized in black or any one of 15 other custom colors. Check their website for the additional colors.

The average price for your specific custom automatic or standard shift aluminum radiator is approximately $600 with anodizing slightly more, and manufacturing usually takes 3-4 weeks. An outstanding benefit of aluminum over copper/brass is that it’s 40% lighter than a standard unit, which is a considerable front-end weight savings. Plus, aluminum is a more efficient heat conductor than copper/brass/lead radiators, allowing the large 1.25-inch cores to transfer damaging heat to the coolant much faster. These Mark 7 radiators will cool up to 750-horsepower in 100-degrees ambient temperature with the A/C running! Now that’s cool!
