Design Engineering, Inc.’s (DEI) Heat Shield Liner for the ’21-’24 HD Sportster S 1250 Stock Exhaust Pipe (#901086) is a revolutionary product in Powersports, designed to enhance rider comfort while preserving the bike’s stock look. Heat produced by the exhaust system can make the rider uncomfortable—especially in slow traffic moments. DEI’s Heat Shield Liner reduces radiating heat targeted on the rider’s legs by insulating the outer heat shield, improving overall comfort without compromising the attractive lines and appearance of the bike.
Each piece of the Heat Shield Liner is precision-cut to fit seamlessly between the exhaust pipe and the heat shield, effectively blocking heat transfer and lowering the surface temperatures of the outer shield. The dual-layer construction of Aluminum and DEI’s proprietary Dura 2000™ insulating material ensures durability and long-lasting performance. Installation is simple, do it yourself, and requires no permanent modifications to the bike, keeping the liners completely hidden once installed. Made in the USA, DEI’s Heat Shield Liner exemplifies top-quality craftsmanship and innovation in riding experiences.
