The Muncie 48TK5546 is a welded extension shaft installation kit for the Muncie EX Drive system, specifically matched to Allison 4000 series transmissions equipped with a retarder. The EX Drive eliminates traditional driveline installations by allowing large gear or piston pumps to direct-mount to the PTO. This kit is part of the EX Drive family, which features a wet spline design for extended spline durability and a steel housing system. The EX Drive is available for the A20, A30, A40, A50, and CS40/41 PTO families, with SAE B, BB, and C output configurations as well as DIN 5462. Call us to confirm proper fitment for your specific transmission and PTO combination.
