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

If you're the proud owner of an S54-equipped BMW, chances are you're passionate about enhancing your vehicle's performance and longevity. One crucial upgrade that can significantly improve your driving experience is Turner Motorsport's WPC Rod Bearing Replacement Kit, coupled with ARP Rod Bolts for increased durability.

Enhanced Durability: The WPC Performance Rod Bearing Replacement Kit is designed with superior materials and manufacturing processes. WPC treatment reinforces the surface of the bearings, making them highly resistant to wear, which is essential for high-revving engines like the S54. This durability ensures your engine will stand the test of time, even under strenuous driving conditions. Improved Performance: By reducing friction and wear, WPC-treated rod bearings allow for smoother and more efficient engine operation. 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:

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.
