Dart Cam Bearings
If you're building up a Dart block and want the best bearings with the correct sizing, then you'll want Dart cam bearings. They're fully grooved, made from steel-backed babbit, and specifically designed for high performance use. To all of this, Dart adds their own moly-PTFE coating for even better performance and durability. This coating is approximately 0.0005 in. thick, which translates into 0.001 in. less overall clearance.

Dart Valve Stem Seals
Dart valve stem seals are designed to control the lubrication of the valve stem as it slides in the valve guide. Too little oil causes stem and guide wear. Too much oil increases oil consumption and can cause a buildup of carbon, leading to valve seat damage and an early valve grind. Available in different styles and sizes, Dart valve stem seals are just what you need to take control of your oil.

Dart Stud Girdles
Dart stud girdles can help to improve the performance and reliability of engines equipped with stud-mounted rocker arms. Extra-long adjusting nuts are tightly clamped between rigid aluminum bars that prevent stud deflection under high loads.

Unlike universal girdles, these valvetrain stabilizers are designed to fit the specific valve locations, valve angles, and valve lengths in Dart cylinder heads. These kits include hardened poly-lock adjusting nuts.

Dart Intake Manifold Gaskets
Dart intake manifold gaskets are designed to provide excellent sealing properties to avoid leakage and help maximize performance.

You can help to prevent that from happening by equipping your vehicle with Dart gaskets. They're made from durable composite material to address tough sealing issues and to help ensure a tight, leak-proof seal.

Dart Replacement Valve Springs
Valve springs are one of the most critical and overlooked components in your engine. They must be matched to your cam in order for the engine to reach its full potential. It does absolutely no good to install a cam that will rpm to 8,000 if you do not have the correct springs. Use only the valve springs that will give the recommended spring pressure with the valve both on the seat and at maximum lift. These Dart replacement valve springs are offered in single and dual styles to meet their cam requirements.

Dart Freeze Plugs
Durable steel freeze plugs from Dart work like expansion plugs. As we all know, water expands when it turns to ice, and if the coolant in your vehicle doesn't have enough antifreeze protection, it can freeze and then crack the engine block. Dart freeze plugs are designed to pop out under such conditions to relieve the pressure on the block, thus protecting it against freeze damage.
