Product Overview

Our Cum mins NT855 STC Upper Engine Gasket Set is an upgraded heavy-duty top-end sealing solution specially engineered for Cum mins NT855 STC, NTA855 STC and Big Cam STC series 14L diesel engines. This professional upper overhaul gasket kit covers all OEM-matched top-end sealing parts required for cylinder head replacement, valve train service, manifold repair and complete upper engine in-frame overhaul. Designed exclusively for STC (Step Timing Control) engine structures, it perfectly solves common STC engine  points including cylinder head gasket blowout, high-temperature coolant leakage, intake/exhaust air leakage, valve cover oil seepage and compression pressure loss. Adopting reinforced high-temperature resistant MLS composite and anti-fatigue rubber materials, this NT855 STC upper gasket set delivers superior pressure resistance and thermal stability, effectively adapting to long-term heavy-load, high-temperature and high-vibration working conditions, and permanently fixes recurring top-end sealing failures.

Compatible Engine & Equipment Applications

This NT855 STC top end gasket set strictly follows OEM dimensional standards for 100% precise fit with all Cum mins NT855 STC, NTA855 STC and Big Cam STC diesel engines. It is a dedicated repair kit for STC timing control versions and not universal with non-STC Big Cam engines, widely applied in global heavy-duty industrial and commercial equipment:
  • Heavy-Duty Construction Machinery: Large loaders, motor graders, excavators, bulldozers and off-road mining equipment
  • Commercial Heavy Trucks: Class 8 heavy-duty semi-trucks and cargo transport vehicles equipped with NT855 STC powertrain
  • Industrial Power Generation: Stationary diesel generator sets, emergency power units and continuous-operation industrial power equipment
  • Marine & Special Machinery: Commercial marine auxiliary diesel engines and large agricultural heavy machinery

  • Reinforced MLS multi-layer steel cylinder head gasket, STC-version exclusive, anti-blowout and high-pressure resistant
  • High-temperature resistant valve cover gasket and buffer sealing cushions
  • Precision intake manifold & exhaust manifold sealing gaskets for STC timing structure
  • Full set of heat-resistant valve stem oil seals for high-temperature operation
  • Upper engine cooling system gaskets and coolant passage sealing rings
  • STC mechanism auxiliary sealing gaskets and precision positioning gaskets
  • All matching upper engine paper gaskets, rubber O-rings and sealing accessories

Key Features & Advantages

  • STC Version Exclusive Precise Fit: This upper gasket set is professionally customized for Cum mins NT855 STC step timing control engine structure, perfectly matching STC-specific valve train and timing assembly parameters. It supports direct bolt-on installation without cutting or modification, solving the problem of ordinary gaskets failing to fit STC engines.
  • Superior High-Temperature & Anti-Blowout Performance: Adopting upgraded thickened MLS metal composite structure and high-temperature resistant materials, it effectively resists extreme combustion temperature and explosion pressure of NT855 high-power engines. It thoroughly avoids common failures such as head gasket bursting, cylinder pressure leakage and engine overheating caused by inferior gaskets.
  • Excellent Vibration & Fatigue Resistance: Optimized for long-term high-vibration operation of construction machinery, all sealing parts feature strong compression recovery and anti-deformation ability. It maintains stable sealing tightness under continuous heavy-load operation, preventing recurring air and oil leakage.
