The Shacman X5000 Welding Assembly Of Bumper Lower Frame is an OEM structural kit for Shacman X5000 and X3000 trucks. This heavy‑duty assembly includes the bumper lower frame, lower trim panel brackets, left and right reinforcement plates, plus 22 welding square nuts (M8 and M10). Designed to restore the lower bumper structure after corrosion or impact damage, it ensures proper alignment for trim panels and grilles.
The Shacman X5000 Welding Assembly Of Bumper Lower Frame Bumper Lower Frame (DZ9718962304) is a fabricated steel assembly that forms the lower structural support for the front bumper. Made from 3mm thick high‑strength steel, it integrates mounting points for the lower trim panel, fog lights, and splash shield. The frame is e‑coated black, providing 720h salt spray resistance. It replaces rusted or bent original units, restoring bumper rigidity and correct ground clearance.
Two stamped steel brackets (2mm thickness) that attach the lower trim panel to the main lower frame. Powder‑coated black, each bracket includes rubber isolators to eliminate rattle. Pre‑drilled with M6 weld nuts for easy screw attachment. Direct replacement for damaged or missing brackets. Includes alignment tabs for error‑free positioning.
Left side reinforcement plate, laser‑cut from 4mm steel, zinc‑plated. Welds onto the lower frame corner to increase rigidity and provide additional tow hook mounting strength. Designed to prevent frame bending during winching or recovery. Includes pre‑weld alignment dimples.
Mirror image of the left plate, reinforcing the right lower frame corner. 4mm thick steel with zinc flake coating. Improves impact resistance and distributes loads from the right bumper support. Sold as a pair with the left plate for balanced strength.
22 pieces total: 12x M8 welding square nuts (Q37106) and 10x M10 welding square nuts (Q37108). Both are zinc‑plated, projection‑welding type. M8 nuts provide captive threads for trim and bracket bolts; M10 nuts secure main frame bolts. After welding, each nut withstands 80 Nm torque without rotation. Essential for a professional frame restoration.

Complete kit – includes lower frame, trim brackets, reinforcement plates, and all 22 welding nuts (M8 and M10). No missing parts. Ready for professional welding and assembly.
Heavy‑duty steel: 3‑4mm thickness, e‑coated or zinc‑flaked. 720h salt spray resistance. Welding nuts meet ISO 13918 standards, pull‑out force >8 kN.
OEM fitment – all brackets and plates match Shacman X5000/X3000 original dimensions. Reinforcement plates prevent frame twisting during towing. 24‑month warranty.
Restores lower bumper structure and trim alignment. Eliminates rattles and sagging trim. Includes rubber isolators on trim brackets for noise‑free operation.
The lower frame of the bumper is frequently exposed to road salt, curbs, and minor impacts. Over time it can rust through or bend, causing the lower trim panel to sag and fog lights to misalign.
This Shacman X5000 Welding Assembly Of Bumper Lower Frame kit provides a complete replacement solution. It includes the main lower frame, two trim panel brackets, left/right reinforcement plates, and all welding nuts.
The main lower frame is fabricated from 3mm thick steel tube and stamped sheet, welded together in a jig to ensure precise geometry. It directly replaces the original part without modification.
All steel components are e‑coated (cathodic epoxy) or zinc‑flaked, offering superior corrosion protection for harsh environments.
Bumper Lower Frame: weight 6.8 kg, outer dimensions 1400mm wide × 200mm high × 80mm deep. Constructed from DC04 steel with 3mm wall thickness. Integrated mounting points for splash shield (6x M6 holes).
Lower Trim Panel Brackets: 2mm thick stamped steel, black powder coat. Each bracket has two M6 weld nuts. Includes 3mm thick rubber pad to dampen vibration. Bolt spacing 80mm.
Left & Right Reinforcement Plates: 4mm thick S355MC steel, zinc flake coating. Add 40% more torsional rigidity to the lower frame corners. Include pre‑welded M10 nuts for tow hook attachment.
Q37106 (M8 welding square nut): 12 pieces. Dimensions 15x15x5mm, thread M8x1.25, class 8. Four projection bumps. Recommended welding current 7‑9 kA, electrode force 2.2 kN. After welding, thread must be re‑tapped with M8 tap.
Q37108 (M10 welding square nut): 10 pieces. Dimensions 18x18x6mm, thread M10x1.5, class 8. Six projection bumps. Welding current 9‑11 kA, force 2.8 kN. Used for main frame attachment to chassis brackets.
Both nuts are zinc‑plated (12µm) and supplied with anti‑spatter oil. Storage in dry conditions below 40°C. Do not weld through paint or heavy rust.
Step 1: Remove old lower bumper frame, trim panel, and any damaged brackets. Clean chassis mounting surfaces to bare metal.
Step 2: Position the new lower frame onto the chassis (use jack stands to support). Tack weld the left and right reinforcement plates onto the frame corners first.
Step 3: Weld the 12 M8 square nuts and 10 M10 square nuts onto the frame using a resistance welder at the marked locations. Follow recommended welding parameters.
Step 4: Weld the lower trim panel brackets to the front face of the frame (fillet weld 4mm leg length). Ensure brackets are level.
Step 5: Install the completed lower frame assembly onto the truck using M10 bolts into the welded M10 nuts (torque to 45 Nm). Reattach splash shield and lower trim panel using M6 bolts into M8 nuts.
Step 6: Reinstall fog lights, grille, and wiring. Test all attachments for secure fit. Final torque check after 100 km.
Rusted‑through lower frame – new e‑coated frame restores structural integrity. Sagging lower trim panel – new brackets with rubber pads hold trim firmly. Bent reinforcement plates – fresh 4mm plates prevent twisting. Missing or corroded weld nuts – all 22 nuts included, no need to source separately.
Salt spray test (ASTM B117): 720h on steel components – red rust <5% on cut edges. Coating adhesion (cross‑cut) result 0. Vibration test (ISO 16750‑3): 10‑500Hz, 4.3 Grms, 48h – no cracks in welds, no nut loosening.
Impact test: 10 km/h pendulum – lower frame bends but does not detach; reinforcement plates prevent tearing. Weld strength exceeds base metal strength.
Thermal cycling: -40°C to +80°C, 100 cycles – no distortion, no coating delamination.
Direct fit for Shacman X5000 (2019‑2026) and X3000 (2015‑2026) with plastic bumper covers. Also fits X6000 with minor modification to trim bracket holes. Verify original lower frame part number DZ9718962304.
All‑in‑one solution: 6 part numbers consolidated into one kit, saving procurement time. Lower repair cost: 70% less than dealer assembly. Reduced downtime: welding and installation under 2 hours.
Improved safety: reinforcement plates protect the radiator during low‑speed impacts. Higher resale value: documented frame replacement.
Yes, a MIG/MAG welder for the reinforcement plates and brackets, plus a resistance welder for the square nuts. Most truck repair shops have this equipment.
No, standard nuts cannot be welded and will fall off. Use only the included projection welding nuts.
Use M6 bolts into the welded M8 nuts with 8 Nm. Do not exceed 10 Nm to avoid stripping.
They are highly recommended if you use the tow hook. Without them, the lower frame may bend during heavy pulling.
24 months on materials and weld integrity (if welded per instructions). Excludes collision damage or improper welding.
The pre‑weld dimples on the frame guide placement of the square nuts, saving layout time. The reinforcement plates are laser‑cut with beveled edges for easier weld penetration.
All components are bagged with labels and include a welding parameter card. Technical support: downloadable PDF includes jig drawing, torque chart, and weld sequence – available via catalog button.
Steel components are made from 35% recycled material. E‑coat is water‑based, low VOC. Packaging uses 100% recycled cardboard, no plastic. Extends truck service life.
A collision repair center in Chicago used the Shacman X5000 Welding Assembly Of Bumper Lower Frame kit on 18 Shacman X5000 trucks with rotted lower frames. The Shacman X5000 Welding Assembly Of Bumper Lower Frame complete kit allowed them to finish each repair in 1.5 hours (weld + assembly). The included welding nuts eliminated the need to drill and tap holes, saving 30 minutes per truck. No warranty claims after 2 years. The shop reported a 50% increase in profit margin on bumper repairs.
Patch repairs using angle iron often result in misaligned trim and weak welds that crack under vibration. Our one‑piece lower frame with factory‑spec welding nuts provides consistent strength. Aftermarket “universal” brackets never fit correctly; our brackets are laser‑cut to match original bolt spacing. Generic hardware rusts quickly; our welding nuts have zinc plating and projection rings designed for proper fusion.
