Balance Shaft Hub With Connecting Shaft & Bracket Combined Assembly OE 2904010-K2001 for Dongfeng KC Heavy Trucks

This OE 2904010-K2001 balance shaft assembly is an integrated one-piece casting unit combining connecting shaft, two balance bearing hubs and mounting brackets, eliminating separate purchase and assembly of scattered brackets and hubs, greatly shortening maintenance time. The whole body is cast with high-toughness ductile iron, and thick reinforcing ribs are distributed around the connecting shaft and hub bases to disperse torsional stress evenly, effectively preventing casting cracking under long-term heavy load bump vibration. Each hub central bore is pre-pressed with self-lubricating alloy composite bushing, forming an oil storage layer to reduce metal dry friction, lower chassis abnormal knocking noise and extend service cycle without frequent manual grease filling. Evenly distributed symmetrical mounting bolt holes on both bracket bases are precisely CNC machined, hole position and aperture fully copy Dongfeng KC original frame layout, plug-and-play whole-unit installation without cutting or reaming. Full black anti-rust coating covers every casting gap to block rainwater, mud and road salt corrosion.

Heavy truck chassis maintenance technicians often face severe suspension overhaul troubles caused by split aftermarket balance shaft parts: scattered separate brackets, hubs and connecting shafts require multiple alignment and assembly steps, wasting a lot of repair hours; thin ordinary cast iron parts lack reinforcing ribs, easy to crack under mining road heavy load torsion; ordinary copper bush without self-lubricating layer wears rapidly, producing loud knocking noise and damaging balance shaft journal. This genuine DFCV OEM integrated balance shaft combined assembly completely eliminates these hidden troubles: one-piece unit simplifies installation; thick ductile iron shell resists cracking; pre-installed self-lubricating bush reduces wear, cutting suspension overhaul frequency and chassis component matching costs for heavy truck fleets.

As a core integrated load-bearing buffer spare part of Dongfeng KC heavy truck chassis suspension system, this combined balance shaft assembly fully complies with Dongfeng Commercial Vehicle official chassis casting component production quality standards. Every finished whole unit completes three mandatory professional durability laboratory tests: static full-load bearing pressure test, millions of times alternating torsion fatigue cycle test, continuous salt spray anti-corrosion aging test, maintaining stable buffering performance under long-distance highway, dusty mining area and cold winter salt road transportation environments. Metal nameplate with OEM serial number and part number is pasted on the casting surface for genuine product traceability, all overall length, central hub bore diameter, mounting hole spacing and connecting shaft arc size strictly follow original vehicle factory engineering drawings, zero assembly mismatch after whole-unit replacement.

We are authorized Dongfeng wholesale supplier of genuine DFCV OEM chassis suspension spare parts for Dongfeng KC heavy trucks, maintaining permanent sufficient stock of OE 2904010-K2001 integrated balance shaft combined assemblies. Each large cast iron whole unit is wrapped with thick shockproof bubble film and reinforced wooden pallet packaging to prevent casting edge collision deformation and coating scratch during cross-border sea and land logistics transit. Its pre-assembled dual hubs and standard bilateral mounting holes allow professional chassis maintenance technicians to finish full balance shaft replacement within 50 minutes without separate matching of brackets or hubs, drastically cutting vehicle downtime for logistics fleets and heavy truck suspension noise & crack repair garages. We provide a 24-month anti-crack and low-wear structural quality warranty plus free remote chassis frame mounting matching installation guidance for all worldwide bulk wholesale buyers.
