Balance Shaft Support Bracket OE 2904061-K2202 for Dongfeng KC Heavy Trucks

This OE 2904061-K2202 balance shaft bracket is integrally cast with high-toughness ductile iron, with thickened internal and external reinforcing ribs distributed around the bearing hole, greatly improving structural rigidity and impact resistance, avoiding bracket cracking under heavy load bumping. The central bearing inner hole adopts one-time CNC precision finishing, with uniform smooth inner wall to ensure close fit with balance shaft bearing, eliminating bearing loose shaking and abnormal chassis noise. Multiple symmetrical standard bolt holes are reserved on left and right extension plates, completely copying Dongfeng KC frame mounting hole layout, no cutting or reaming required during installation. The full black anti-rust coating penetrates every casting gap, blocking rainwater, mud and road deicing salt to prevent rust perforation. The overall arc transition design reduces stress concentration, dispersing chassis torsion force evenly during long-distance heavy haulage.

Heavy truck chassis maintenance technicians often face severe suspension failures caused by inferior balance shaft brackets: thin ordinary cast iron brackets lack reinforcing ribs, prone to crack and fracture under heavy load mining road vibration; rough unprocessed central bore leads to bearing loose fit, generating abnormal knocking noise and accelerating bearing wear; non-OEM irregular mounting hole spacing requires cutting and welding modification, wasting maintenance time and causing hidden danger of loose fixing. This genuine DFCV OEM balance shaft bracket completely solves these risks: thick reinforced ductile iron resists cracking; precision machined bore holds bearing tightly; standard hole spacing realizes direct bolt-on installation, cutting suspension overhaul frequency and chassis component replacement costs for heavy truck fleets.

As a key load-bearing suspension spare part of Dongfeng KC heavy truck chassis system, this balance shaft support bracket fully complies with Dongfeng Commercial Vehicle official chassis casting component production quality standards. Every finished bracket 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 structural integrity under long-distance highway, dusty mining area and cold winter salt road transportation environments. Serial number and OE code label are pasted on the bracket body for genuine product traceability, all overall length, bearing bore diameter, mounting hole spacing and rib layout 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 2904061-K2202 balance shaft support brackets. Each cast iron bracket 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-standard multi-position mounting holes and precision bearing bore allow professional chassis maintenance technicians to finish full bracket replacement within 35 minutes without refitting frame gaskets or custom processing holes, drastically cutting vehicle downtime for logistics fleets and heavy truck suspension noise & crack repair garages. We provide a 24-month anti-crack and anti-rust structural quality warranty plus free remote chassis frame mounting matching installation guidance for all worldwide bulk wholesale buyers.
