Gearbox Gears / Crown Wheel and Pinion

OEMatch Gearbox Gears, Crown Wheel & Pinion — Engagement, Smoothness, Control

OEMatch supplies gearbox gears, crown wheel and pinion for Porsche models. These precision-cut components are offered as direct-fit replacements engineered to match original-spec dimensions and tolerances, providing a practical option when genuine parts are unavailable. They are suitable for restoration, gearbox rebuilds and upgraded applications where attention to ratio and durability is required.

• Standard-ratio gearbox gears for road use
• Performance-ratio gears for modified engines and track use
• Crown wheel and pinion sets for differential rebuilds

OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original gearbox gears and crown wheel & pinion.
OE (Original Equipment) refers to parts matching original specifications for the gearbox gears and crown wheel & pinion and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM gearbox gears and crown wheel & pinion engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.

These components are typically cut from case-hardened steel, finished with precision machining and balanced to control noise and wear. Correct tooth form, surface treatment and hardness are key to long service life and smooth torque transfer, and selection should reflect the vehicle’s intended use.

• Restores quiet, efficient gearbox and differential operation
• Reduces gear noise and backlash when fitted correctly
• Improves torque delivery and throttle response in rebuilt gearboxes

• Contaminated or degraded gearbox oil leading to accelerated wear
• Pitting and scoring from overload or insufficient lubrication
• Misalignment caused by worn bearings or damaged housings
• Heat distortion from sustained high-load or track use
• Incorrect installation or backlash setting errors

Replacing worn or damaged gearbox gears, crown wheels and pinions restores drivetrain precision and helps maintain consistent power delivery in Porsche models. Fitted parts correct gear engagement, reduce stress on bearings and shafts and support long-term reliability after a rebuild. OEMatch items are selected to align with Porsche specifications and to assist technicians and restorers in matching ratios and installation requirements.

• Available in standard and performance ratio options for restoration or upgrade projects
• Manufactured and finished to control noise and minimise wear
• Supplied with information to support correct installation and setup

Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified. If you are unsure about setup, bearing condition or backlash settings, consult a specialist with Porsche experience.
