Valve Keeper

TRW Engine Components is a recognized developer of valves and valve train components. A wide range of materials and material combinations are used to meet the engineering requirements in the different engine applications. Materials vary from ferritic martensitic steels (intake valves) and austentic CrMn based steels to extreme heat and corrosion resistant Nickel base super alloy for exhaust valves. To improve wear and corrosion resistance, valves can be chromium plated or nitrided. These coatings are used to improve the compatibility of the valve stem surface to the valve guide material. If necessary, exhaust valves (and in some cases also intake valves) can be hard-faced. In hard-facing, a more heat and wear resistant material is welded to form the valve seat. Seat hard-facing extends the valve life significantly.

Product Features:

• OE Quality
• Optimized for strength
• Heat and corrosion resistant
• Chromium plated or nitrided
• Stem optimized to resist wear

ARP only uses premium grade 8740 alloy and a proprietary ARP2000 alloy that are rated for superior to “aircraft” quality alloy steels. Secondly, each stud is placed vertically into special racks and precisely heat-treated to 200,000 psi for the 8740 material and 220,000 psi for the ARP2000 material. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers who just dump pieces in a basket and hope for the best. 

Product Features:

• 12mm 12-Point, 4mm Allen Socket Size(s)
• ARP2000
• Black Oxide
• BMW 2.5L, 3.0L, 3.2L
• Sold As A Kit

Metaloflex Cylinder-head Gaskets Elring cylinder-head gaskets are high-tech components used in modern combustion engines. As key components, they help to ensure that engines run efficiently, reliably and economically. Developed by ElringKlinger, Metaloflex is a globally recognized brand of innovative metal layer cylinder-head gaskets made of beaded, elastomer-coated spring steel layers. Multilayer steel cylinder-head gaskets are available in various bead designs and with a different number of layers, depending on the OE specification of the respective car manufacturer. Metaloflex gaskets may be of single or multi-layer design depending on the application. Thanks to the modular design elements, this sealing system can be individually adapted to suit the requirements of the specific engine. This technology avoids the need for time-consuming, costly iterative processes whilst guaranteeing maximum engine design flexibility.

Product Features:

• Produced from spring steel for long-lasting flexibility of beads
• Thermal stability up to 600F
• Full or partial FPM surface coverage of head and block layer for micro-sealing of liquids and combustion gas – extended service life
• Heat treatment of functional layers further enhances gasket durability and this technology is exclusively applied to ElringKlinger metal gaskets
• Tightening instructions provided with each gasket for perfect results

Fel-Pro gaskets offer 100% vehicle sealing with application-specific materials to give you sealing solutions with the performance and durability professionals trust
