The Wilwood 370-0877 is an outer tapered roller bearing cone with a 0.750-inch inside diameter, made of steel with a bare finish. The manufacturer lists it under the LM11949 designation as a hub cone for its disc brake and drag hub assemblies. Wilwood states that its bearings are built to tight tolerances for performance and long life, and the cone is sold separately from its matching race, the 370-0876 cup. Buyers replacing a worn outer bearing in a Wilwood hub should choose this cone when the hub already uses the matched set, because the manufacturer warns against mixing cups and cones from different bearing sets. Owners searching for an LM11949 outer cone, a 370-0877 hub bearing, or a 0.750 ID Wilwood drag hub cone will find this is the correct cone for that matched set.
Fitment is set by the hub, not the vehicle alone. The manufacturer's dimensional data sheet lists 370-0877 as the outer cone for a range of hubs, including 1955-57 Chevrolet, 1967-74 Nova, Galaxie, Camaro 1970-78, AMC, and C-body applications, so confirm your hub part number against that chart before ordering. For installation, Wilwood's assembly sheets for its hub kits call for packing the outer cone with high temperature disc brake bearing grease, sliding the hub onto the spindle, tightening the bearing nut to 60 in-lb while turning the hub, then backing the nut off one slot and fitting a new cotter pin. Users on forums also stress that a bearing packer makes greasing the cone much cleaner. Keep the cup and cone matched, and do not reuse a worn cup.
The manufacturer advises against mixing cup and cone bearings between bearing sets, because bearing diameter, roller angle, or width may be incompatible with the race. Keep the cone paired with its matched cup.
The manufacturer states that individual race (cup) and bearing (cone) parts are available for purchase separately.
The manufacturer's dimensional data sheet for Wilwood hubs, bearings, and seals lists 370-0877 as the cone for several hub part numbers and vehicle applications, including 1955-57 Chevrolet, 1967-74 Nova, Galaxie, and AMC hubs. Verify your hub part number against that chart before ordering.
Installation is a standard drum or disc hub bearing job for anyone comfortable working on the spindle, but it requires care with greasing and preload. The manufacturer's assembly sheets for Wilwood hub kits recommend packing the cone with high temperature disc brake bearing grease and tightening the adjusting nut to 60 in-lb while rotating the hub, then backing the nut off one slot and installing a new cotter pin. Their warnings note that failing to back off the adjusting nut can make the bearing run hot. Plan on a bearing packer for clean grease fill, a torque wrench for the adjuster, and fresh cotter pins and seals. Confirm the procedure against the specific Wilwood hub kit's instructions before you start.
