The 5.4L Triton engine is a flagship product at Fraser, renowned not just for its sales but for its performance over the past decade. We uphold the highest standards of quality and integrity, ensuring we never compromise on the work we deliver. Although the 5.4L Triton is known for certain issues, like cam phaser and oil pump problems, we at Fraser Engines have proactively addressed and rectified these concerns. This commitment to improvement and reliability is why it remains our top seller year after year.
Fraser Engines takes the 5.4L 3 Valve Triton Engine to new levels of durability and performance, addressing common issues with precision and advanced engineering. Our comprehensive updates ensure that every engine exceeds OEM standards, providing peace of mind and enhanced functionality for all applications.
Solutions for Spark Plug Issues Understanding the critical nature of the spark plug issues, Fraser Engines reinforces the engine heads with welding to create a new, more robust surface. We then meticulously drill and tap to add more threads than the original factory engine, effectively resolving the notorious problem of spark plugs blowing out and thread issues.
Upgraded Timing Components for Premium Performance To eliminate timing failures, we incorporate the latest OEM timing components, including upgraded tensioners and guides. This upgrade is designed to prevent chain slap and failure, ensuring smooth operation and extended engine life.
Valve Train Redesign Every engine benefits from entirely new valves, locks, guides, seats, rockers, and lifters. This comprehensive overhaul addresses any potential valve failure and significantly reduces valve train noise, guaranteeing a quiet and reliable performance.
High-Flow / High Volume MELLINGS M-360 Oil Pump Installation An updated high-flow oil pump is installed in each engine to meet the lubrication demands of critical components, especially at the top end. This ensures constant lubrication and protection under all operating conditions.
Advanced Piston Technology We equip our engines with hypereutectic graphite-coated pistons, designed for a tighter fit and reduced wear over the engine’s lifespan. This technology not only enhances performance but also prolongs the durability of the engine.
Multi-Layer Steel Head Gaskets for Superior Sealing To combat cylinder head gasket failures, Fraser Engines installs new OEM multi-layer steel head gaskets. These gaskets are specifically chosen for their ability to withstand the high operating temperatures of the 5.4L Triton engine, providing exceptional sealing and heat resistance.
