Camshafts

Unlock the full potential of your S54’s valvetrain with our High Performance Cam Followers/Rocker Arms, built for precision, durability, and reliability in high-revving performance engines.

Crafted from forged chromoly steel and finished with a diamond-like carbon coating, these cam followers are engineered to deliver exceptional strength, reduced friction, and outstanding wear resistance, ideal for demanding street or track use. Each unit is precision-ground for consistent clearances and smooth, stable valvetrain motion at all RPMs. Despite heavy-duty construction, our design retains the same weight as the factory rocker arm, preserving OE valvetrain geometry and balance while offering superior longevity and performance.

Rocker arms wear in conjunction with the camshafts, meaning the two must be replaced simultaneously. Aftermarket and performance camshaft options (Schrick, CAT-Cams, etc.) are typically ground from softer blanks and, as a result, cannot be used with factory rocker arms. We tested our performance cam followers with aftermarket camshafts to validate compatibility, ensuring smooth, reliable, and safe operation under demanding conditions.

Features:

Forged chromoly construction for maximum strength and durability Diamond-like carbon-coated surface reduces friction, extends service life, and permits compatibility with aftermarket and performance camshaft options Precision-ground tolerances ensure consistent and quiet operation OEM weight match maintains valvetrain balance and reliability Superior wear resistance for performance and endurance applications NOTE: Rocker arms are wear items and must be replaced alongside a new set of camshafts, regardless of profile or manufacturer. Installing a new set of rocker arms onto a used set of camshafts is NOT recommended.

This eccentric shaft is a vital component of your BMW's N55 Valvetronic system, responsible for precise control of valve lift. In the N55 engine, the Valvetronic system uses intermediate levers between the camshaft and lifters to adjust valve lift dynamically. These levers are actuated by this eccentric shaft, which is rotated by an electronically controlled motor under the direction of the engine computer.

Eccentric shaft failure is a common issue in N55 engines, often caused by inadequate lubrication due to extended oil change intervals. The most frequent failure occurs when the eccentric shaft gear wears down, leading to disengagement from the motor's worm drive. Symptoms include multiple fault codes, such as P1014 (Shaft Parity Error), P1017 (Shaft Sensor Plausibility), P1023 (Valvetronic Adjustment Range), and P10E1 (Valvetronic System No Travel Detected).

If your BMW is experiencing Valvetronic-related fault codes, a failing eccentric shaft could be the source of the problem. Opt for this premium direct replacement from Bremmen Parts to restore your Valvetronic system's functionality and ensure a durable, high-quality repair.
