Shacman X5000 Front Leaf Spring Lug Assembly is an OEM front spring mounting component that secures the leaf spring to the chassis. It includes the front spring lifting lug and a durable bushing.
Manufactured by Shacman, this assembly ensures proper articulation and load distribution. The Shacman X5000 Front Leaf Spring Lug Assembly prevents spring eye wear and maintains axle alignment.
The Front Spring Lifting Lug (Part SZ970000027) is a forged steel bracket that attaches the front leaf spring eye to the chassis frame. It is manufactured from high‑strength 42CrMo4 steel, heat treated to 38-42 HRC. The lug features a precisely reamed hole (30mm diameter) for the bushing and two 16mm mounting holes to the frame rail. Its design allows the spring to pivot freely while limiting lateral movement. The lug has an integrated grease nipple to lubricate the bushing. It is hot‑dip galvanized with 85μm zinc coating, providing 800h salt spray resistance.

The Bushing (Part 199000520078) is a press‑fit rubber‑metal component that isolates vibration and allows angular movement of the leaf spring eye. It consists of an inner steel sleeve (30mm ID), a natural rubber element, and an outer steel shell (40mm OD). The rubber has a Shore A hardness of 65 and is bonded to both sleeves using high‑temperature vulcanization. The bushing provides a torsional stiffness of 800 Nm/rad and radial stiffness of 12,000 N/mm. It is designed to withstand 5 degrees of angular misalignment. The inner sleeve is phosphatized for corrosion resistance. This bushing eliminates metal‑to‑metal contact between the spring eye and the lifting lug, reducing noise and wear.

Applications
Shacman X5000, X3000, F3000 front leaf spring suspension. Also fits MAN TGA front spring eyes.
Certifications
IATF 16949, ISO 9001. Material certificates EN 10204 3.1 available.
Press bushing into leaf spring eye using a hydraulic press (force 30-40 kN). Ensure bushing flanges are flush. Apply anti‑seize on outer surface of bushing to ease pressing. Mount lifting lug to chassis frame using new M16 grade 10.9 bolts, torque 200 Nm. Insert spring eye into lug and secure with through bolt (M30) torque 450 Nm. Grease the fitting until grease purges from bushing edges.
Re‑torque all bolts after 500 km. Inspect bushing rubber for cracks annually. Replace if bushing inner sleeve rotates by hand.
Front Spring Lifting Lug: closed‑die forged, normalized, CNC machined. 100% dye penetrant and ultrasonic tested. Hot‑dip galvanizing to ISO 1461. Bushing: inner/outer steel sleeves are precision machined, rubber injection moulded and bonded. Adhesion tested per ASTM D429. Hardness measured in 5 points.
Each Shacman X5000 Front Leaf Spring Lug Assembly is batch coded. Grease filled and sealed in plastic bag. Torque retention bolts supplied separately.
Worn lugs and bushings cause clunking, uneven tire wear and spring leaf cracking. Replacing with genuine Shacman X5000 Front Leaf Spring Lug Assembly extends spring life by 50% and improves ride quality. Greaseable lug reduces maintenance intervals. Lower total cost of ownership versus welding repairs.

Clunking from front suspension over bumps, visible bushing rubber cracking or missing, lug hole elongation, rust bleeding from joint, spring eye misalignment. Replace immediately with Shacman X5000 Front Leaf Spring Lug Assembly to prevent spring failure and axle shift.
Inspect every 100,000 km. Check lug bolts for tightness with torque wrench. Lubricate every 20,000 km.
Aftermarket lugs are often cast iron or low‑carbon steel (not forged), prone to cracking. Bushings use recycled rubber that hardens in one year. Our genuine Shacman X5000 Front Leaf Spring Lug Assembly uses forged steel and original‑spec rubber compound. The hot‑dip galvanized coating outlasts paint by years. Choose genuine for safety and longevity.
Final recommendation: Always replace both the lifting lug and bushing as a set. The Shacman X5000 Front Leaf Spring Lug Assembly provides a complete, matched solution for front suspension mounting. Trust genuine Shacman for original quality and durability.
