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.

Kit Contents:

24 DLC-Coated Rocker Arms (required to complete both camshafts) Product Development: Our Turner Performance Rocker Arms are the result of advanced engineering, testing, and quality assurance by Turner’s Research & Development team. Every stage of development employs FARO laser scanning, SolidWorks 3D CAD modeling, and in-house rapid prototyping for precise fitment and design validation. Performance and durability are proven through Mustang AWD 500 SE dyno testing and Superflow SF-750 Flowbench analysis, ensuring each component meets Turner’s uncompromising standards for performance and quality.

What's better than using standard connecting rod bearings in your next engine build? Using our Turner Motorsport WPC-treated bearings! Our process begins with King Engine Bearings bearing shells. Designed with performance and load capacity in mind, King's SV Series bearings feature a Lead-free, tri-metal Silver-based overlay with a Babbitt plating made to provide seizure resistance. Ideal for extreme-load engines, it serves as an OE replacement and can be employed as a sputter replacement. Despite offering great wear and friction resistance, the engineers at Turner Motorsport saw an opportunity to further improve King's bearing design with WPC surface treatment. WPC reduces friction and adds strength, vastly enhancing the durability of critical internal engine components. Ultra-fine particles are fired at the surface at very high speeds—similar to shot-peening, but on a much smaller scale. The treated parts come out smoother and stronger due to thermal discharge. The two greatest enemies of any high-performance engine are heat and friction, and WPC technology effectively reduces both.

Upgrade your BMW engine's performance with the Athena Cut Ring Head Gasket. This gasket replaces BMW part # 11121726619 and 11121726617 and is specifically designed for M50 & M52 iron block inline 6-cylinder engines found in E34/E36 chassis. Standard OEM & MLS gaskets can only handle a certain amount of cylinder pressure before they start to leak, making the Athena Cut Ring Head Gasket the recommended choice for applications making 16+ psi. A compression leak passing the head gasket can cause a range of issues, including engine overheating, loss of power, misfires, and in severe cases, catastrophic engine failure. Athena's gasket is crafted with premium quality reinforced M0115, an asbestos-free material that's original equipment approved and renowned for its superior quality. The AISI 304 stainless steel Cooper Rings bite into the aluminum head, providing maximum sealing capabilities around the cylinder bore and optimizing engine performance, even on engines with nitrous and/or turbo applications that exceed 2-bar boost. Before installation, it is crucial to have the mating surfaces of the cylinder head and block professionally cleaned and resurfaced to ensure they are completely flat. Please be aware that the gasket should have a size that is 0.5mm to 1mm larger than the piston. For example, if the piston measures 84mm, then the gasket should be the next size up, either 84.5mm or 85mm. Installation instructions: Make sure that the engine block and cylinder head surfaces are clean, flat, and free from any debris, oil, or coolant. Install the Cut Ring gasket on the engine block and ensure that it is properly aligned. Avoid twisting or bending the gasket during installation. Place the cylinder head on top of the gasket and install the head bolts or studs in their correct positions. Follow the manufacturer's recommended torque specifications and tighten the bolts or studs in the proper sequence to ensure even clamping force across the gasket. After the initial tightening, re-torque the head bolts or studs after the engine has been started and then allowed to cool to room temperature. This will ensure that the gasket is properly seated and compressed. It is recommended to not use any additional sealant on the MLS gasket, as it is already coated with a Viton rubber sealant. Using additional sealant can hinder the performance of the gasket.

If you're not sure if your Vanos seals are bad then the only question you need to answer is if you've replaced them. Every unit from the factory came with the same failure prone o-rings and seals, even the re-manufactured units you can still get today. The only real fix is by replacing the seals and o-rings with material that is built to last in the oiled, extreme temperature environment found in these kits. 

A premium product replacement with easy to follow instructions makes rebuilding your Vanos unit a must. Even thought the power loss is barely felt it's the opposite result once you replace the seals, every car that gets rebuilt ends up wowing the customer and all of them saying they didn't realize what they lost. 

There are a number of symptoms that will plague your car as a result of these failing seals such as erratic idle, engine hesitation, stalling, and increased fuel consumption to name a few. If you've been chasing down any of these symptoms with no fix then this could be your issue.

5150 High-Performance Coated Rod Bearing Sets are made for the demands of high-performance engine builds. Treated shells and coated by Calico to reduce friction, these bearings allow your engine to generate more power and resist "spinning" under stress. These coated bearings also have thermal resistant properties that not only perform in high HP applications like forced induction or race use, but also help prevent sudden engine failure in the event of oil pressure loss. 5150 bearings have proven themselves on and off the track, lasting longer and outperforming other bearings on the market. Tech Notes: As with all bearings, please check your tolerances and size before installation. Due to the specialized tools needed, professional install recommended.
