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. The valve motion more closely follows cam profile, producing more power and reducing breakage. 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 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.
