The centerpiece of this MMX kit is the UK-made CNC-machined one-piece crank hub, created from billet EN36 steel that's heat-treated with a 0.75mm case hardening, making it incredibly strong and durable. Included are four aerospace precision-machined dowels that mechanically lock the hub to the end of the crank itself, plus a brand new OE bolt. Installation of these dowels is certainly not a DIY job. But, to make the job easier for the professionals, ensuring that the required crank modifications are made safely and accurately, the MMX kit also includes a full installation jig that includes a bolt-on drilling guide, a location bolt for this guide, plus an HSS rolled high-speed drill bit. Together, the single-piece design combined with the four-pin location ensures that there is simply no way that the friction plates can ever slip. With the new OE crank bolt tightened appropriately, this delivers a transformational improvement in reliability and peace of mind versus the OE version. Also included is the MMR Crank Bolt Capture Plate. This adds one additional layer of defense, preventing the crank bolt from being able to back out and loosen over time, ensuring everything is tightly held together as intended.

Both the N55 and S55 engines are plagued by the same issue when chasing high horsepower numbers... the dreaded crankhub failure. Fortunately MMR Performance has released an upgraded version of their already stout single-piece crankhub, but this time offering a 4-pin dowelled location that locks onto the front of the crankshaft. This configuration eliminates the multi-piece crankhub with friction discs in favor of a more robust single piece crankhub. Recommended for high-powered cars over 700 Horsepower

Anyone with a modified N55/S55 knows the risks involved with the OEM Crank Hub. When the engine simply can't handle the stresses its put under or the design is such that it simply does not support extreme conditions, issues can arise. Under certain conditions, the N55/S55 crank hub likes to spin, without warning and even when the engine is in perfect health. MMR has produced a EN36 machined billet one-piece crank hub heat treated with a 0.75mm case hardening which makes it extremely durable. Due to the one-piece design, it ensures that the friction plates cannot slip. This offers a huge jump in reliability when paired with a new properly torques crank bolt. Installation is requires no drilling or modification to the OEM crankshaft ensuring a perfect fit! Included in this kit is MMR's T-6061 machined billet aluminum capture plate anodized in their trademark finish. The MMR Performance capture plate secures the head of the OE crank bolt and prevents it from turning or being able to loosen. *Installation recommended by a professional shop or technician.

Carrillo rods are your number one option for performance connecting rods! If you are looking to upgrade your N20 engine to handle greater power, we highly recommend these Pro-H connecting rods. Upgrading connecting rods in your engine can bring several benefits, particularly if you're looking to enhance performance, reliability, and overall durability. Here are some reasons why you might consider investing in upgraded connecting rods: Increased Strength: Upgraded connecting rods are often made from stronger materials, such as forged steel or titanium, compared to stock rods. This increased strength helps withstand higher levels of stress and load, making them suitable for high-performance applications. Improved Durability: Enhanced materials and manufacturing processes contribute to improved durability, reducing the risk of connecting rod failure, especially in high-stress situations. This is crucial for engines that undergo frequent high-speed or high-stress conditions, such as in racing or heavy-duty applications. Higher RPM Capability: Upgraded connecting rods are designed to handle higher engine RPM (revolutions per minute) without succumbing to fatigue or deformation. This is beneficial for those seeking increased horsepower and torque at higher engine speeds. Reduced Weight: Some upgraded connecting rods are engineered to be lighter while maintaining strength, contributing to a lower overall rotating mass in the engine. This can result in quicker revving, improved throttle response, and better overall performance. Enhanced Precision: Upgraded rods often undergo more precise machining processes, ensuring tight tolerances and improved balance. This precision can lead to better engine stability and reduced vibration, ultimately extending the life of engine components. Compatibility with High-Performance Builds: If you're planning on modifying your engine for increased horsepower through methods like turbocharging or supercharging, upgraded connecting rods become essential. They provide the necessary strength and reliability to handle the increased stresses associated with forced induction. Prevention of Catastrophic Failures: Upgrading connecting rods can act as a preventive measure against catastrophic engine failures. The improved strength and durability reduce the risk of a connecting rod breaking, which could lead to severe engine damage. Specifications: CC(in): 5.683 CC(mm): 144.35 Style: PRO-H Bolt Size: 3/8 Bolt Type: WMC Pin Width(in): 0.822 Pin Width(mm): 20.88 Big Width(in): 0.822 Bid Width(mm): 20.88 Big Bore(in): 2.1112 Big Bore(mm): 53.62 Pin Size: 22mm QTY: Set of 4 Founded by Fred Carrillo in 1963, Carrillo Connecting Rods was established with an unwavering commitment to uncompromising standards in manufacturing.

This foundational philosophy remains as strong today as it was at the inception of Carrillo in 1963. At CP-Carrillo, quality and pride are inseparable. The process of crafting a CP-Carrillo rod transcends mere forging, production targets, and shipping deadlines. The evolution of connecting rod design has become a collaborative effort involving skilled specialists. Each connecting rod is a precision symphony, with material specialists, forging experts, production craftsmen, design engineers, and engine specialists contributing their expertise and artistry. Customer feedback plays a pivotal role in our continuous product improvement. The close interaction between customers, engineering, and manufacturing fosters the most effective rod designs, enhancing accuracy and service—a value that becomes apparent during your engine build.
