It includes the naked double-forged rod, crankpin, bearings, and thrust washers. It requires specialized mechanical press tools and balancing fixtures to install onto your existing factory crankshaft webs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What are the exact structural measurements for this 0923-0365 rod kit?\u003c\/strong\u003e\u003cbr\u003eA: This kit features a center-to-center length of 92.50 mm, a big end bore diameter of 38.00 mm, a big end width of 18.00 mm, and a pin end bore of 16.00 mm.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why is a forged barreled rod style preferred over basic cast variants?\u003c\/strong\u003e\u003cbr\u003eA: Forged steel provides a tightly compressed grain layout that offers vastly superior resistance to stretching, twisting, and fracturing under the abrupt load spikes common to high-compression four-stroke dirt bikes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e Pressing a new connecting rod kit is a high-precision job that requires a heavy hydraulic shop press and an ultra-accurate dial indicator alignment setup. When splitting and rebuilding the crank webs, the final crankshaft assembly must be trued to less than 0.015mm (less than a thousandth of an inch) of runout. If your crank is trued poorly, it will generate extreme harmonic vibrations that will tear up your new main bearings, cause oil pump failure, and ruin your engine cases within a few hours of track time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-yz250f-yz250fx-performance-parts-and-accessories\"\u003eYamaha YZ250F \/ YZ250FX Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-4-stroke-dirt-bikes-performance-parts-accessories-moto-house-mx\"\u003eYamaha 4-Stroke Performance Parts\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/mx-off-road-motorcycle-tools\"\u003ePremium Case Splitters \u0026amp; Crankshaft Tools\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
