The Merchant Automotive Steel Seal Driver Handle fits all of our CNC-machined billet aluminum seal drivers and installers. That includes the engine front and rear main seal drivers, every transfer case seal driver, and the Allison 1000 pump bushing installer. The driver slips onto the end of the handle, and the included O-ring holds it securely in place.

You get a solid striking surface and the reach to drive seals and bushings in straight, square and to the correct depth. The same handle is included in our Transfer Case Seal Driver Kit, and it's sold separately if you buy individual drivers or need a replacement.
