Balance Shaft Hub With Bushing Assembly OE 2904080-TK500 for Dongfeng KC Heavy Trucks

This OE 2904080-TK500 balance shaft hub shell is integrally cast with high-toughness ductile iron, thick wall and internal reinforcing ribs disperse torsion stress evenly, effectively preventing hub cracking under long-term heavy load bump vibration. The pre-pressed self-lubricating alloy composite bushing inside the central bore forms an oil storage layer, greatly reducing dry friction between hub and balance shaft, lowering chassis abnormal knocking noise and extending service cycle without frequent grease filling. Evenly distributed flange mounting holes around the hub are precisely CNC machined, hole position and aperture fully copy Dongfeng KC original balance shaft bracket layout, plug-and-play installation without cutting or reaming. Bilateral integrated suspension connecting lugs adopt smooth transition arc design to avoid stress concentration fracture, and full black anti-rust coating covers every casting gap to block rainwater and mud corrosion.

Heavy truck chassis maintenance technicians often face serious suspension failure caused by inferior balance shaft hubs: thin ordinary cast iron hub lacks 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; non-OEM irregular flange hole spacing requires on-site cutting and reaming during replacement, wasting maintenance hours and causing loose fixing hidden danger. This genuine DFCV OEM balance hub assembly completely eliminates these hidden troubles: thick ductile iron shell resists cracking; built-in self-lubricating bush reduces wear; standard flange holes realize zero-modification installation, cutting suspension overhaul frequency and chassis component replacement costs for heavy truck fleets.

As a key rotating buffer spare part of Dongfeng KC heavy truck chassis suspension system, this balance shaft hub with bushing fully complies with Dongfeng Commercial Vehicle official suspension casting component production quality standards. Each finished hub assembly completes three mandatory professional durability laboratory tests: millions of times alternating torsion fatigue cycle test, long-term bushing friction wear life 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. OEM serial number and part number label are attached on the hub outer surface for genuine product traceability, all hub outer diameter, central bore size, bushing thickness and flange hole spacing strictly follow original vehicle factory engineering drawings, zero assembly mismatch after 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 2904080-TK500 balance shaft hub with bushing assemblies. Each cast iron hub is wrapped with thick shockproof bubble film and reinforced wooden carton packaging to prevent casting edge collision deformation and coating scratch during cross-border sea and land logistics transit. Its pre-pressed integrated bushing and standard flange holes allow professional chassis maintenance technicians to finish full hub replacement within 40 minutes without refitting balance shaft bracket or custom processing holes, drastically cutting vehicle downtime for logistics fleets and heavy truck suspension noise & wear repair garages. We provide a 24-month anti-crack and low-wear structural quality warranty plus free remote chassis balance shaft matching installation guidance for all worldwide bulk wholesale buyers.
