Antrys Tractor Lower Lift Arm Bushings — 10pc pack, Galvanized Iron Cat II→I Adapter, Anti‑Wobble

Antrys 10Pcs Tractor Lower Lift Arm Bushing adapts Category II lift arms to Category I implements for a tighter, wobble-reducing hitch connection.

These universal lower lift arm bushings (302910 / 30291E1 family) are made from iron with a galvanized finish and are sized to fit the common 1-1/8" OD, 7/8" ID, 1-3/4" length dimensions. Sold in packs that keep spares on hand, they convert Cat 2 lift arm mounts to accept Cat 1 hitch pins and reduce lateral play, helping your tractor and implements work together with less stress and smoother movement. Compatible with multiple OEM numbers, they’re designed to meet or exceed original equipment tolerances for strength and fit.

How do these bushings improve my tractor-to-implement connection?

By converting Category II lift arms so they accept Category I implement pins, the bushings close gaps that cause slop and unpredictable movement. That tighter fit decreases shock and side-loads on the hitch assembly and helps implements track truer behind the tractor.

• Reduces lateral play for steadier implement operation
• Distributes load to limit concentrated stress on components
• Galvanized iron resists deformation under heavy use
• Standard dimensions allow predictable, repeatable fit

Which tractors and implements will these bushings fit?

These are universal Category II-to-I lower lift arm bushings that match common industry sizing and numerous part numbers, so they fit many makes and models. Cross-reference the listed part numbers or measure your lift arm bore and implement pin diameter to confirm compatibility.

• Matches part numbers: 302910, 30291E1, 87760407, EC0NG992AA, and others
• Fits lift arm bore accepting 1-1/8" outer diameter bushing
• Works with implements using Category I pins (7/8" pin clearance)
• Suitable across brands when dimensions and fit are confirmed

What are the material and durability features I should expect?

Manufactured from high-quality iron with a galvanized coating, these bushings are built to handle heavy loads and exposure to weather and grit. The finish helps slow corrosion while the iron core resists bearing deformation, giving longer service life than untreated alternatives.

• Galvanized iron construction for rust resistance
• Engineered to withstand repeated hitch cycles and loads
• Dimensionally stable to preserve snug fit and reduce wear
• Sold in multi-packs so you have spares for maintenance

How do I install and maintain these bushings for best results?

Installation is straightforward: press or tap the bushing into the lift arm bore, align the implement pin, and secure with the appropriate hardware. Routine inspection for wear and lubrication where applicable keeps the interface functioning smoothly and signals when replacement is needed.

• Press or gently tap bushing into clean, deburred bore
• Confirm 7/8" pin clearance and 1-1/8" outer seating
• Inspect periodically for scoring, looseness, or corrosion
• Replace in matched sets to maintain consistent geometry

Who is this for: Farmers, landscapers, and equipment technicians who need a reliable, cost-effective way to adapt Category II tractor lift arms to Category I implements. If you want to reduce hitch wobble, protect hitch components from uneven wear, or keep common implements compatible across tractors, these Antrys bushings provide a durable, easy-to-install solution with cross-referenced OEM numbers for straightforward replacement.
