Replacing the rod bearings requires mechanical knowledge and skill, a clean workspace, and several specialist tools. Our preferred procedure is to leave the engine in the car but remove the front subframe. The engine must be supported from above with an engine brace. Removing the front subframe involves disconnecting the control arms and steering rack and steering column. The oil pan can then be removed and you can access the connecting rods and bearings. Replacing the rod bearings themselves is straightforward but patience and forethought will be extremely helpful. In addition to analyzing the severity of the rod bearing wear, the crankshaft must also be inspected closely for damage. Rod bearings that have been severely worn may have damaged the crankshaft (requiring replacement or machining).

The S54 engine has a known history of rod bearing failure, and if your engine is higher mileage, don't let this catastrophic failure happen to you. Replace your rod bearings and prevent a spun bearing which can trash your crankshaft. WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both. Kit includes Upper and lower WPC treated rod bearings for extra protection against wear Hardware Oil filter Castrol TWS Edge Professional Oil pan gasket Oil pan cover gasket RedLine assembly lube Connecting rod bolts

Enhanced Durability: The WPC Performance Rod Bearing Replacement Kit is designed with superior materials and manufacturing processes.

This increases power and responsiveness, providing a more exhilarating driving experience. Whether tearing up the track or enjoying a spirited weekend drive, you'll notice a difference in your vehicle's performance. Precision Engineering: Crafted from premium quality materials, these bolts and bearings offer exceptional tensile strength and structural integrity. This guarantees that your connecting rods will stay securely in place, even during high-stress situations. Your engine's components will work in perfect harmony, minimizing the risk of catastrophic engine failure. Preventative Maintenance: The S54 is notorious for rod bearing failure, often necessitating complete short block replacement. Choosing to proactively replace your rod bearings with our WPC offering ensures smooth operation and eliminates potential engine failure. Included in the kit:

The S54 engine has a known history of rod bearing failure, and if your engine is higher mileage, don't let this catastrophic failure happen to you. Replace your rod bearings and prevent a spun bearing which can trash your crankshaft. BE Bearings, in conjunction with Clevite, an OE bearing manufacturer, have redesigned and manufactured the bearings for greater clearance and have changed the original material composition from tin-aluminum to lead-copper. This upgrade incorporated the state-of-the-art Clevite Tri-Metal design and featured a Tri-Armor™ coating. This allows for the additional lubrication for wear prevention, plus, the softer bearings are better for your engine and are more tolerant of foreign particles suspended in your oil. Another benefit from this is that the oil can now be sent for testing to accurately gauge the amount of wear occurring in the engine.

Schrick has been dedicated to engine performance through the development of only the highest quality camshafts for more than 40 years. They've created a bond with BMW enthusiasts nearly the entire time, offering options for both the street and track, using top materials for strength and accuracy. Schrick has grown into a technology center offering one of the most advanced locations for engine testing and manufacturing.

These are a direct replacement for the stock camshafts and offer increased flow at mid and higher RPMs, thanks to 12.5mm of valve lift. Unlike 288/280 camshafts, this 280/272 set does not require upgraded valvetrain parts. The profile of these camshafts is quite close to stock CSL specs.

KIT INCLUDES

Schrick 272-Degree Exhaust Camshaft Schrick 280-Degree Intake Camshaft 24 Turner Motorsport DLC-Coated Performance Rocker Arms NOTE: Camshaft replacement requires multiple special tools. We offer the Genuine BMW Camshaft Press (T#171829) and a Schwaben Camshaft Alignment Tool Set (T#395239) to aid in installation.

These cams are a direct replacement for the stock cams and give a solid 15+ horsepower boost at the top end and great midrange torque increases too! More gains can be expected with intake and header upgrades and custom software tuning. A slightly lumpy idle is expected at cold start, but will be smooth once at operating temperature.

These Schrick cams were initially developed for the M3 CSL, but they also work well on the US and other non-CSL S54 engines. With more duration, they are a great match to high-flow headers and CSL intake plenum upgrades.
