E-9N555B Lower Lift Arm for Ford/New Holland
Brand: Eparts, Inc. | Interchange: A-9N555B, 103208 WN-9N555B, HF9N555B, JSA1002R, JSA1002B, 3013-1633 | Package: 1 | Compatible with Ford/New Holland tractors 2N, 8N, 9N, NAA (1953–1954).
Best for classic Ford/NH tractors needing a direct lower lift arm replacement. This option offers reliable interchange compatibility with several part numbers, ensuring fitment on vintage 2N/8N/9N models. Limitation: check exact hole pattern and sway chain requirements on offset variants.
3-Point Lower Lift Arm Fits Ford Tractor D0NN555C
Brand: JJAgParts | Category: Ford, multiple models listed including 501, 541, 2111; Offset holes for sway chain may require drilling. Center-to-center and side mounting arrangements vary by model.
Best for Ford tractors requiring a wide compatibility list, including offset models with sway chain considerations. Choose this if you operate several older Ford variants and need a broad-fit arm. Caution: some offsets require drilling for sway chain on installation.
26 1/2″ Lower Lift Arm CAT 1
Brand: Neat Attachments | Features: 7/8″ ball end hole; center-to-center distance 24″; overall length 26-1/2″.
Best for Category 1 tractors needing a mid-length lift arm with standard ball-end hitch compatibility. This item is a straightforward match for many universal Cat 1 3-point hitch setups. Limitation: verify exact ball-end hole size and drilling requirements on specific tractor models.
30 3/4″ Lower Lift Arm CAT 1
Brand: Neat Attachments | Features: 7/8″ ball end hole; center-to-center of hole 30″; overall length 33″.
Best for tractors needing a longer reach to accommodate larger implements or deeper mounting points. Choose this if your current lift arms are too short for your attachments. Limitation: longer arms may affect clearance on tight-swing operations.
6″ Tall Stack Extension Adapters
Brand: Anrain | Features: 49mm pin diameter; 6″ tall; 4-piece set; 12,000 lbs total capacity. Designed for 2-post lifts, not tractor-specific.
Best for shop-wide versatility when working with heavy-duty vehicles and needing additional lift height in a stall or service bay. Avoid using these adapters as primary tractor lift arms; they are intended for lift systems outside tractor 3-point hitch contexts.
Buying Guide
What size lift arm do you need? Measure center-to-center distance between ball ends on your current 3-point arms and compare to the listed lengths (26-1/2″, 30″, and similar). Consider your implement clearance and the maximum lift height required by your attachments.
Which category and mounting pattern apply? Most Cat 1 arms fit standard Category 1 hitch pins, but offsets and sway chain requirements vary. For tractors with offsets, be prepared to drill a sway chain hole if the item specifies it.
Material and durability: Look for high-strength steel with appropriate finish to resist wear and corrosion. Longer arms can flex differently under load; ensure the hardware and mounts can handle your typical workloads.
Compatibility and interchange: When shopping, verify interchange numbers and model compatibility (Ford/NH, 2N/8N/9N/NAA, etc.). This reduces the risk of misfit and reduces on-hand inventory needs.
Installation notes: Some arms require additional hardware or mounting adjustments. Confirm whether sway chains, holes, or extra brackets are needed for your specific tractor model.
