Inside a
Motorsport
Engine
The components that make performance possible.
Explore the EngineMore Than Just Horsepower
A motorsport engine is a carefully engineered system where every component has a job to do. From the bearings supporting the crankshaft to the valves controlling airflow, each part has to work precisely and reliably under extreme conditions.
Performance isn't simply about producing more power. It's about creating an engine capable of delivering that power consistently, efficiently and reliably.
Performance isn't just about how much power an engine produces. It's about how reliably every component can deliver it.
Where the Power Starts
The bottom end is where combustion power is transformed into mechanical movement. The crankshaft, connecting rods, pistons and bearings all work together thousands of times every minute.
- Crankshaft main bearings
- Connecting rod bearings
- High-performance pistons
- Piston rings
- Connecting rods
Precision Where It Matters
Engine bearings operate between some of the most highly loaded moving components inside an engine. Their job is to maintain a precise oil film while controlling friction and supporting the crankshaft under extreme loads.
In motorsport applications, bearing selection, clearance and material construction become especially important when engines are operating at high RPM and load.

Designed to Take the Heat
Pistons operate at the heart of the combustion process, exposed to intense heat and pressure with every cycle. Their design, material and ring package all play a role in controlling combustion and maintaining reliability.
- High-performance piston designs
- Precision piston rings
- Heat and load resistance
- Controlled oil consumption
Controlling Airflow
Airflow is fundamental to engine performance. The cylinder head controls how efficiently air and fuel enter the combustion chamber and how exhaust gases leave it.
- Performance valves
- Valve guides
- Valve seats
- Valve springs
- Valvetrain components
Sealed. Secured. Ready.
High-performance engines need components that can maintain sealing and clamping integrity when temperatures, pressures and loads increase.
Head Gaskets
Designed to maintain a reliable seal between the cylinder head and engine block under demanding combustion pressures.
View GasketsARP Fasteners
High-performance fasteners provide controlled clamping force for critical engine assemblies.
Explore ARPPrecision Sealing
Seals and gaskets help keep oil, coolant and combustion gases where they belong.

Keeping Everything in Sync
The timing system controls the relationship between the crankshaft and camshaft, ensuring the valves open and close at exactly the right moment.
- Timing belts
- Timing chains
- Tensioners
- Idler pulleys
- Timing gears and guides
Every Component Has a Job
Motorsport performance comes from the interaction of hundreds of individual components. Each one has to perform its role while working as part of the complete engine system.
