When heavy-duty trucks travel thousands of miles on highways, construction sites and rough terrain, the clutch system bears constant shock, friction and heat. A reliable clutch disc directly decides drivability, safety and uptime for semi-trucks and commercial fleets. As demand for long-lasting aftermarket transmission spare parts keeps rising across North America, Europe and Australia, Terbon is proud to introduce our brand-new 15-1/2” x 2” ceramic clutch disc with OE reference 128539.
Severe Duty Performance
This 387mm 6-paddle ceramic clutch disc is engineered for severe duty applications. Unlike standard organic clutch plates, the ceramic friction pads deliver outstanding heat resistance and higher torque capacity. For fleet owners, repair shops and truck rebuilders, it means less slipping under heavy loads, stable power transfer during frequent starts and stops, and much longer service life compared to conventional clutch discs.
Precision Engineering
Each of the six ceramic pads is firmly riveted to the clutch cover assembly. Built-in spring dampers absorb drivetrain vibration, reducing gear rattle and driver fatigue. Precise spline machining ensures smooth installation, matching the fitment requirements of OE 128539. There is no need for extra modification during replacement, helping mechanics cut installation time and labor cost.
Quality Assurance
Consistent quality control runs through every production step at Terbon. All raw materials are tested for friction coefficient, heat resistance and mechanical strength before mass production. Finished clutch discs go through dimensional inspection and torque load testing, to guarantee performance matches OEM specifications. As an aftermarket manufacturer specializing in truck brake and transmission components, Terbon understands that fleet operators cannot afford unexpected breakdowns. Reliable spare parts reduce downtime and lower total operating costs over the vehicle’s lifespan.
Global Aftermarket Solution
This ceramic clutch assembly (15-1/2 x 2 inch) serves as a perfect aftermarket replacement for heavy commercial trucks. It is widely chosen by wholesale distributors, truck repair garages and fleet maintenance teams globally. Whether customers are looking for small trial orders or large bulk shipments, Terbon provides flexible MOQ and professional technical support for clutch parts selection.
