The Stromberg Carlson BC-108 Rack & Ride is a four-bicycle, hanging-style carrier with frame cradles and rubber retaining straps. Its removable adapter allows mounting in either a 1¼-inch or 2-inch hitch receiver. Use the original assembly diagram below to identify the support tube, folding arms, hitch pin, cradles and individual fasteners.

These numbers correspond to the manufacturer's illustration. They identify the parts included with the complete rack, rather than individual orderable replacement part numbers. When replacing a lost or damaged component, confirm its number and your BC-108 model with us.
Install in a 1¼-inch or 2-inch receiver
For a 1¼-inch receiver, the manual calls for the anti-rattle pin, flat washer, spring washer and retaining clip. For a 2-inch receiver, fit the included adapter sleeve and secure the rack with the anti-rattle pin and clip. Insert the pin from the driver's side as shown in the manufacturer's Figure 3, and tighten with a ¾-inch wrench.
The two pivot connections use hex bolts and locknuts. Tighten the lower connection securely while allowing the support tube to pivot as illustrated, then install the bail pins to hold the upright and arm assemblies in place.
Secure the frame cradles and check the load
Each of the eight cradles has its own rubber strap. Position the bicycle frames in the arm cradles, fasten the straps over the tubes and alternate bicycle directions if needed for handlebar clearance. The number of bicycles that can actually fit depends on their frames and handlebars; never exceed the 120 lb combined bicycle limit.
For installation on a suitable RV bumper, the BA-100 accessory receiver guide explains the separate bumper adapter and its restrictions. The BC-202 platform rack uses wheel trays instead of hanging cradles, and the CC-275 Bike Bunk positions a rack above a trailer A-frame.
