The Genie 28678-2250GT is a genuine OEM Nylon Sleeve, 2" ID built for the Z-51/30J articulating boom lift. Sourced directly from Genie, this sleeve meets the same dimensional and material standards as the part installed at the factory. Cross-reference part number 28678-2250GT against your Z-51/30J parts manual to confirm it is the correct item for your machine before ordering.
Key Features
- Genuine OEM Material Grade — Nylon construction meets the dimensional and material tolerances specified for the 2" ID bore, ensuring the sleeve seats correctly without play or binding.
- Exact 2" ID Specification — The 2" inner diameter matches the mating component precisely, making installation straightforward with no alteration needed.
- Confirmed Fitment — Designed specifically for the Genie Z-51/30J articulating boom lift, so you can order with confidence that this is the correct OEM part for that machine.
- Wear Protection — A nylon sleeve reduces friction and absorbs load between mating surfaces, protecting surrounding metal components from accelerated wear when the sleeve is kept in good condition.
A nylon sleeve acts as a low-friction bearing interface between two mating components — typically a pin and a bore — cushioning contact, reducing metal-to-metal wear, and maintaining correct alignment under load. When a sleeve wears through or cracks, the pin and bore it protects begin to wear directly against each other, leading to slop in the joint, unusual movement, and damage that is far more costly to repair than a sleeve replacement. Installing a correctly sized OEM sleeve keeps the joint operating within its designed tolerances and extends the service life of the surrounding structure.
