About This Unit The BW1128F was introduced by BorgWarner in 2011 as the OEM manual shift transfer case for the redesigned 4th-generation Ford F250, F350, F450, & F550 Super Duty trucks, and remained in production through 2016. It directly replaced the NP271F transfer case after New Process Gear / New Venture Gear ceased production, with the transition happening partway through the 2011 model year. Some early-production units from the transition period carry an MP1128F tag instead of BW1128F — these are the same unit, just identified by an earlier tagging convention used during the changeover. Whether your tag reads BW1128F or MP1128F, this listing covers both. The 1128F is a chain-driven, two-speed unit featuring a 43-spline input shaft, mated specifically to Ford’s 6R140 TorqShift six-speed automatic transmission. Common OEM assembly numbers include BC34-7A195-BB, BC34-7A195-CC, and other variations in the BC34 series. Whether you’re running a 6.7L Powerstroke diesel, a 6.2L Boss V8, or a 6.8L Triton V10, the BW1128F is the correct factory-spec replacement for any 2011-2016 F250/F350/F450/F550 trucks equipped with the manual shift / lever on the floor 4WD system. *Note* Please provide us with the Model & Assembly Number when ordering.
