Keep contaminants out of the front steering rack with the Mevotech Supreme Rack and Pinion Bellows Kit (MK9857). This kit drops in as a direct-fit replacement for the 1990-1994 Mazda 626 and the 1992 Mazda MX-6, installing the protective boots that shield the rack shaft and inner tie rods on the front rack-and-pinion steering.
The bellows seal the ends of the steering rack, keeping dirt, moisture, and road debris away from the rack shaft and inner tie-rod sockets. When the original boots crack, tear, or loosen, contamination gets in and accelerates wear — replacing worn bellows helps protect those components during service.
Signs the bellows may need replacing: a torn, cracked, or split boot; grease slung around the rack ends; or contamination visible inside the boot. See the "Vehicles it fits" section for the full application list.
