Timing Covers

Timing covers protect your engine’s timing components from dirt, debris, and oil contamination while helping maintain proper alignment for reliable operation. A quality timing cover ensures a tight seal, reduces the risk of leaks, and keeps critical components like the timing chain or belt functioning smoothly. Whether you're rebuilding an engine or upgrading for performance, a durable timing cover is essential for long-term reliability.

Rocker Arms

Rocker arms transfer the camshaft’s lift and motion to the valves, making them a critical part of the valvetrain’s performance and reliability. Upgraded rocker arms improve valve control, reduce friction, and support higher RPM and lift levels. Whether you’re building a street engine or a high-performance setup, quality rocker arms help ensure smooth, efficient valve operation and long-lasting durability.

Camshafts

Camshafts control the timing and movement of your engine’s valves, directly shaping power, torque, and throttle response. Upgrading to a performance camshaft increases airflow, enhances combustion efficiency, and unlocks stronger performance across the RPM range. Whether you're aiming for a smooth street build or an aggressive high-RPM setup, the right camshaft transforms how your engine performs.

Valley Covers

Valley covers seal and protect the lifter valley area of your engine, keeping debris out while helping manage oil flow and crankcase ventilation. Upgraded valley covers improve engine cleanliness, reduce windage, and enhance overall reliability—especially in high-performance applications. They also offer a cleaner, more finished look under the intake manifold.

Camshafts and Valvetrain Q&A

What is the purpose of a camshaft?

The camshaft controls the timing and lift of your engine’s intake and exhaust valves. It determines how air and fuel enter the combustion chamber and how exhaust gases exit — directly affecting horsepower, torque, and overall engine performance.

How do I choose the right camshaft for my engine?

Consider your engine displacement, compression ratio, intended RPM range, and performance goals. Street engines benefit from mild cam profiles with smooth idle, while race or high-RPM builds may require more aggressive lift and duration. Always check compatibility with your cylinder heads and valvetrain setup.

Can I upgrade my valvetrain without changing the camshaft?

Yes — upgrading rocker arms, valve springs, or pushrods can improve durability, stability, and RPM potential even with your existing camshaft. Just ensure all components are compatible in lift range and spring pressure.

What’s the role of a timing chain cover?

The timing cover protects your camshaft timing set from debris and oil loss while maintaining alignment between the crank and cam gears. It also helps prevent oil leaks and ensures consistent timing operation.

What are the signs of a worn camshaft or valvetrain?

Common symptoms include ticking or knocking noises, reduced power, inconsistent idle, or visible wear on lobes and lifters. If your engine shows these signs, it’s best to inspect and replace components before damage spreads.

Can I install these components myself?

Common symptoms include ticking or knocking noises, reduced power, inconsistent idle, or visible wear on lobes and lifters. If your engine shows these signs, it’s best to inspect and replace components before damage spreads.

Can I install these components myself?

If you have mechanical experience and the proper tools, many components can be installed at home. However, camshaft and valvetrain setup requires precision — incorrect lash or spring pressure can cause serious damage. Professional installation is recommended for performance builds.

Do these products come with a warranty?

Yes. All TSP camshafts and valvetrain components include a 1-year limited warranty covering manufacturing defects. Refer to our Warranty & Returns page for full details.
