Rear Leaf Spring Bump Stop Rubber Pad 2911930LE010 for JAC N56/N75/N80 Trucks — Direct-Fit Suspension Buffer, High-Density Rubber
The Rear Leaf Spring Buffer Rubber with OEM number 2911930LE010 is a verified direct-fit replacement for JAC N56, N75, and N80 light trucks. This rubber bump stop pad is a critical component of the rear suspension system, mounted between the leaf spring and the frame or axle to limit spring travel under heavy loads and absorb impact energy over rough roads. It prevents metal-to-metal contact and protects the leaf spring pack from over-compression damage.
- Real Shop Test Data: 100% dimensional inspection using calipers — mounting hole spacing and pad thickness verified within ±[Insert tolerance] mm of OEM specification [Report No. YM-BR-2025-XX].
- Proven Durability: High-density rubber compound rated for [Insert hardness, e.g., Shore A 60–70] and [Insert compression set, e.g., ≤ 25%] — verified by [Insert test method, e.g., compression set test per ASTM D395] [Report No. YM-BR-2025-XX].
- Installation Success Rate: [Insert %] direct fitment — confirmed across [Insert number] repair orders for JAC N56/N75/N80.
- OEM Cross-Reference Verified: Replaces OEM 2911930LE010. Also listed for КАМАЗ Компас-5/9/12 applications in Russian parts databases.
Replace your rear leaf spring buffer if you notice any of the following:
- Harsh bottoming-out sensation over bumps or when loaded — buffer compressed or missing.
- Visible cracks, chunking, or hardening of the rubber pad.
- Metal-to-metal contact noise from the rear suspension.
- Buffer pad detached from its mounting point.
- Leaf spring pack showing signs of over-compression damage.

⚠️ Important Fitment Notes:
- HDA-008 / MC828264 are aftermarket cross-reference numbers, primarily appearing in Mitsubishi Fuso brake booster catalogs. This product is primarily oriented toward ISUZU FSR 6HE1 fitment; the above numbers are listed for customer cross-comparison.
- If your vehicle is a Mitsubishi Fuso FK/FM with an MC828264 booster, confirm pushrod length and mounting bolt pattern match before ordering. "Short" and "long" pushrod variants exist within the MC828264 family.
- Always provide the VIN/chassis number for verification. Do not rely solely on cross-reference numbers.

| Weather resistance | Accelerated UV/ozone test — [Insert hours] |
⚠️ IMPORTANT: Inspect the leaf spring pack for damage before installing a new buffer. A collapsed or broken leaf spring will cause the new buffer to fail prematurely. Replace buffers in pairs (both sides of the axle).
- Support the rear axle and raise the vehicle.
- Remove the old buffer retaining bolts or nuts.
- Remove the old buffer and clean the mounting surface.
- Position the new buffer and install retaining hardware.
- Torque retaining bolts to [Insert spec, e.g., XX N·m] — confirm with workshop manual.
- Lower the vehicle and visually confirm the buffer contacts the spring only under load (not at rest, unless specified).
Inspect buffer rubber for cracks or hardening every 20,000 km or during suspension service. Replace if compression set is visible.
- Each unit is packed in a poly bag with anti-rust protection (for metal inserts), then in a reinforced carton.
- Suitable for: wholesalers, suspension specialists, and fleet maintenance centers.
- MOQ: [Insert MOQ, e.g., 50 pcs] (sample orders accepted).
