Each RPM bulkhead starts with the RPM trademark blend of incredibly strong nylons. From there, RPM redesigned key areas to improve impact resistance but the most significant change comes in the form of lock nuts. After extensive testing and review of damaged stock bulkheads, they found that the most common reason stock bulkheads break is from the mounting screws backing out. RPM's solution was to incorporate a series of lock nuts at the chassis and skid plate mounting holes to securely lock the bulkheads in place. Once the bulkhead is secure, their materials and design changes take over for the strongest, lightest and most durable set of aftermarket bulkheads currently available! RPM front bulkheads are so light, that they weigh less than the stock parts they replace.
