⚠️ 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 MC828264 booster, confirm pushrod length and mounting bolt pattern match before ordering. The "short" vs "long" pushrod variants exist within the MC828264 family.
- Always provide VIN/chassis number for verification. Do not rely solely on cross-reference numbers.

⚠️ IMPORTANT: Suspension fasteners are safety-critical. Always use new nuts when replacing U-bolts. Torque to manufacturer specification — do not reuse deformed or corroded nuts.
- Support the vehicle securely and relieve tension on the rear leaf spring.
- Remove the old U-bolt nuts and inspect U-bolt threads for damage.
- Install new nuts (2912022LE010) onto the U-bolt and hand-tighten.
- Torque to manufacturer specification (refer to JAC N56 workshop manual — typical U-bolt nut torque is in the 150–250 N·m range depending on thread size and grade; verify exact value).
- Re-check torque after the first 500–1,000 km of driving.
- Inspect U-bolt nuts for looseness or corrosion every 20,000–30,000 km or during routine suspension checks.
- Replace if thread damage, corrosion, or loss of clamping force is detected.
- Neutral box, color box, or custom brand packaging available.
- Suitable for: aftermarket distributors, repair shops, fleet maintenance suppliers.
