Wholesale GTB1749V Variable Geometry Turbo BK3Q-6K682-PC Factory Supply Turbocharger 787556-17 854800-5001Wfor Diesel Commercial Vehicles

Product Description

This GTB1749V variable geometry turbocharger is a complete boost assembly engineered to match the 2.2L TDCI diesel commercial vehicle engine, compatible with three cross-reference OE part numbers: BK3Q-6K682-PC, 854800-5001W and 787556-17. Equipped with an adjustable variable nozzle ring, the turbo automatically adjusts airflow passage size according to engine RPM, eliminating turbo lag at low speeds while maintaining stable boost pressure under high-load operation. The turbine wheel is forged from high-temperature resistant alloy, capable of enduring extreme exhaust heat from diesel combustion without deformation. The built-in full floating bearing system relies on engine oil for lubrication and cooling, minimizing internal friction and extending the turbo’s service lifespan. Every finished turbo undergoes dynamic high-speed balancing testing to avoid vibration noise during engine operation.

Key Product Advantages

• Matches three official OE part numbers fully, achieves plug-and-play installation without modifying engine pipelines or brackets.
• Advanced VGT variable nozzle design solves low-speed turbo lag, improves low-range torque and overall fuel economy for delivery vehicles.
• High-temperature alloy turbine wheel resists thermal fatigue, effectively avoiding cracking or blade warping under long-distance heavy-load driving.
• Strict high-speed dynamic balancing process suppresses operational vibration, prevents premature oil leakage caused by unbalanced rotating parts.
• Complete assembly with all factory-matched internal components, saves extra parts procurement time for repair shops and bulk buyers.
