CP Carrillo Heavy Duty Wrist Pin for BMW S58 Engine

Overview

Heavy-duty wrist pin (piston pin) engineered for high-stress, high-power applications in the BMW S58 engine platform. Designed to handle loads exceeding 850 HP, this component connects the piston to the connecting rod and withstands bending and shearing forces. Compatible exclusively with CP Pistons; not compatible with OEM pistons. Sold individually.

Installation summary

Installation of these CP Carrillo heavy-duty wrist pins requires expert-level engine building skills and should only be performed by a professional engine builder or experienced race mechanic due to the extensive teardown required for the S58 engine. The installation process demands precision measuring tools like bore gauges and micrometers to verify exact pin-to-piston and pin-to-rod clearances, along with proper piston heating equipment to ensure correct fitment. The most critical factor to watch out for is that these pins are engineered exclusively for use with compatible CP Pistons and will not fit OEM pistons, making rigorous pre-assembly clearance checks mandatory to prevent catastrophic engine failure. Given the eight-hour estimated labor time and the extreme tolerances involved in high-horsepower S58 builds, professional installation by a qualified engine specialist is strongly recommended.
