Overview

For a high-output engine, the hub-to-crankshaft connection deserves as much attention as the tune. MMX Performance's four-pin single-piece hub adds a positive dowel-drive connection. Choose the capture-plate configuration to secure the crank bolt during the same installation.

Key features

Single-piece heat-treated EN36 steel hub.
Four precision dowels provide a positive connection to the crankshaft.
Drilling jig and drill bit support installation of the locating pins.
Capture plate is available as a selectable configuration.

What's included

Single-piece four-pin crank hub
Four locating dowels and new OE crank bolt
Drilling guide, location bolt and HSS drill bit
Capture plate when selected

Installation and fitment notes

Intended for higher-output builds beyond MMX's recommendation for the unpinned hub.
Installation requires crankshaft drilling and professional engine timing work.
M135i and Touring applications include non-US market vehicles. Match the chassis and engine.
