Often called main bearings, crankshaft bearing shells sit between the rotating assembly and the engine block. They allow the crankshaft to rotate freely, but are prone to wear from deterioration and lack of lubrication.

This complete set consists of nine bearings, enough to fill each journal.

If you're overhauling your M10, choose Hella crankshaft-bearing shells for a lasting solution.

Kolbenschmidt (KS) rod bearing sets are engineered to deliver exceptional performance and reliability, making them an ideal choice for demanding automotive applications. These sets are designed to provide maximum load-bearing capacity, ensuring optimal engine function under heavy loads and high-stress conditions. The use of advanced materials and coatings contributes to anti-seize properties, reducing friction and wear for extended durability.

Manufactured with precision, KS rod bearing sets feature aluminum-tin sliding material combined with an innovative aluminum-zinc-bismuth alloy. This alloy, with bismuth replacing lead, enhances performance while meeting modern environmental standards. The manufacturing process involves casting aluminum strips on-site, followed by carefully coordinated rolling and annealing processes to create composite materials with superior strength and reliability.

One of the standout features of KS rod bearing sets is their innovative coatings, which play a crucial role in ensuring optimal running-in behavior and long-term continuous operation with minimal wear. These coatings range from galvanic films applied electrochemically to electro-physically deposited sputter layers in a high vacuum, as well as synthetic anti-friction coatings. This comprehensive approach to surface treatments enhances performance and longevity, making KS rod bearing sets a top choice for OEM applications.

Features:

Original Equipment Manufacturer (OEM) quality Maximum Load-Bearing Capacity for heavy-duty use Low Wear and Friction for extended service life Advanced Surface Coatings for optimal performance and durability Upgrade your engine's reliability and performance with Kolbenschmidt rod bearing sets, trusted by automotive enthusiasts and professionals worldwide.

The timing chain in any vehicle can begin to stretch and rattle over time. This is a common issue, and though BMW says it is a lifetime part, most enthusiasts decide to change them. If you need only the timing chain instead of a kit, ECS Tuning has your replacement. This is a direct fit replacement for any broken or stretched chain. A great replacement to a damaged chain or one that may have been misplaced out of a timing belt kit.
