Mahle Original Premium Piston Ring Sets
Mahle Original piston ring sets are designed to be installer-friendly. They are pre-lapped to seat immediately, virtually eliminating break-in time. Ring materials and coatings, as well as ring tension, are all optimized for reduced friction and extended life in each application. The compression rings feature a barrel-faced contact area for more efficient compression and CNC-controlled gap chamfer to optimize compression and reduce blow-by. Intermediate rings have a reverse twist design for better groove side sealing, and taper race machining to enhance contact. The CP-20 oil ring assemblies feature a 20 degree ear angle, an exclusive feature that provides the best possible side seal against the cylinder wall, and a special chemical polish on the oil ring expander offers enhanced oil drain back. Mahle Original piston ring sets provide unmatched quality and ease of installation, making them the rings of choice for today's engine builders.

EMPI Extra Capacity Oil Sumps
EMPI extra capacity oil sumps increase oil capacity by 1.5 to 3.5 quarts, which prevents engine oil starvation, improves cooling due to their finned design, and extends oil life. These benefits are particularly advantageous for engines used in high-stress applications like off-road and performance vehicles. The cast, finned design of the sump increases the surface area, allowing oil to dissipate heat more effectively and keeping engine temperatures stable. Better cooling and a larger volume of oil can lead to longer intervals between oil changes, as the oil experiences less thermal breakdown. Kits typically come complete with all necessary hardware, including multiple sizes of pickup tubes to fit various 1200-1600cc engine types. Choose the oil sump model designed for your application needs.

The heart of any hi-performance engine is the crankshaft. EMPI's counter-weighted crankshafts provide several benefits, including reduced crank-flex, harmonics, and vibration for smoother operation, as well as higher RPM performance. With a forged steel construction and nitriding, which also adds to their strength and performance for use in high-performance applications, the crankshafts are precision ground, micro-polished, and dynamically balanced for consistent performance. Other features include cross-drilled and chamfered oil holes and radiused standard/standard VW journals. These advantages are what make EMPI counter-weighted crankshafts ideal for racing applications and perfect for budget-minded racers. Select the crankshafts for your application needs.
