Anti-vibration parts dampen vibration harmonics from the engine and drive line components to rest of the vehicle. This in turn reduces vibration and noise which can be felt and heard while the vehicle is in operation. Rein Automotive anti-vibration parts are application specific and match the design and function of the OE parts

Product Features:

• All Rein Automotive Engine and Transmission mounts are hydraulic or rubber-to-metal based on the original equipment mount design, ensuring the parts performs like original.
• Produced by an Original Equipment supplier
• Manufactured to strict engineering standards/specifications in materials and tolerances
• Rubber components match the shore hardness of the original equipment mount to ensure maximum performance and product longevity
• High corrosion resistance

Goetze OE piston rings for gasoline and diesel engines, are developed for automobile, light commercial vehicle and heavy-duty applications, come in a wide range of sizes, include the first ring sets introduced for Euro4-compliant engines. The end gap can be a straight cut, angled cut or gas tight type for improved sealing. Radial pressure distribution greatly influences ring performance therefore we modify the pressure distribution according to the individual application. The wear-resistance and running-in behavior of the outer ring surface is defined by selecting from various coating options, which include the high-performance electroplated, thermally sprayed and PVD coatings. Goetze modern oil control rings scrape off oil from the cylinder wall, leaving just the required amount for lubrication. The running surface is the contour of the ring facing the cylinder surface. The objective of this running surface profile is to create a lubrication slot with a hydrodynamic film which the piston ring can slide on without touching the other surface. An optimized asymmetrical-barrelled running surface ensures low lubricant consumption even after a very long running time. Goetze piston rings have anti-scuffing properties that promote smooth engine operation, reduced oil consumption and long engine life. In addition, the Goetze process helps prevent materials from detaching and cracking and aids in environmental protection

Product Features:

• Maximum durability
• High wear and corrosion resistance
• Excellent heat-conducting capacity
• Optimal fit

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

Glyco advanced engine bearing technologies withstand heavy loads and cope with the increasingly challenging conditions of modern, environmentally-friendly engines. Glyco is the world’s largest manufacturer of OE-quality bearings. Every year, our engine bearings are fitted on more than 10 million engines around the world – from small bore engines to heavy-duty commercial vehicles and stationary engines. Driven by the need to reduce CO2 emissions, today’s engines extract more power from less fuel. Due to the increased temperature and load, conventional bearings struggle to cope. Thanks to over 100 years of innovation, Glyco provides bearings with advanced metallurgy that can withstand these challenges. Federal-Mogul invented Glyco Sputter Bearings with twice the service life of conventional bearings. Glyco developed G-188, the first intelligent bearing material, and were also first to launch a full lead-free material portfolio. Recent innovations include the highly durable Glyco IROX bearing shells, which address the challenges of hybrid, stop-start and downsized engines.

Product Features:

• Original Equipment Quality
• Excellent wear resistance
• Low propensity to seize
• Reduction in Friction
