The Differential Locker Plate Kit built for the Roper 633a Transaxle is the #1 solution for your quick and easy Differential lock, without sacrificing durability or the ability to revert to stock.
Locker Plates eliminate the 6 planetary gears in the differential and keep the setup welderless! *Note the splined axle 633a use 6 planetary gears (Brake disk setup), while the keyed axle 633a use 4 planetary gears (Brake band setup).* Please review your transaxle and order the correct Locker Plate Kit!
