The design is of a three lobe blower rotor with the BDS logo CNC machined onto the part. Simple to install as the cover uses six 3/8" mounting holes on a 2.782" bolt circle so the cover should work with most all blower snouts. Cover will add a 1/8" so new pulley mounting bolts may need to be purchased. Hex head bolts must be replaced as cover is designed to work only with socket head allen bolts or twelve point bolts.
Cover is made from billet alum. to keep weight down.
Available in black or gray anodize or polished and buyer can chose finish from drop down menu.
