Momo Long Steering Wheel Hub Adapter – Porsche 911 | 6-Bolt Momo Pattern | Aftermarket Steering Wheel Fitment

The Momo Long Steering Wheel Hub Adapter for the Porsche 911 is the required interface component for installing any Momo 6-bolt pattern aftermarket steering wheel on the Porsche 911's steering column — connecting the Momo wheel's 6-bolt mounting pattern to the 911's factory steering column spline and providing the correct steering wheel depth positioning for the long variant. The hub adapter is a safety-critical component — it is the mechanical connection between the steering wheel and the steering column, and correct fitment, correct installation, and correct torque are essential for safe operation. Momo hub adapters are manufactured in Italy to Momo's quality standards and are engineered for correct fitment on the specific vehicle application listed.

Key Features:

• Porsche 911 specific — engineered for the Porsche 911 steering column spline — correct fitment for the 911's factory steering column without modification
• Long variant — the long hub adapter provides additional depth offset compared to the standard hub — positioning the steering wheel further from the dashboard for drivers who require more reach or who are installing a quick-release hub
• 6-bolt Momo pattern — compatible with all Momo steering wheels using the standard 6-bolt Momo mounting pattern — the universal Momo interface used across their full steering wheel lineup
• Safety-critical component — the hub adapter is the mechanical connection between the steering wheel and the steering column — Momo's Italian manufacturing quality ensures correct fitment and structural integrity for this critical application
• Momo quality — manufactured by Momo in Italy — the same brand that has supplied steering wheels and hub adapters to factory race teams for over 60 years

Long vs. Standard Hub — Which Do You Need?

• Long Hub (this product — MOML231): Provides additional depth offset — the steering wheel sits further from the dashboard than with a standard hub. Correct for drivers who need more reach to the steering wheel, for installations where a quick-release hub will be added (the quick-release adds depth, so a long hub may be needed to maintain correct wheel position), or for specific 911 variants where the long hub is the correct fitment.
• Standard Hub: Provides the baseline depth offset — the steering wheel sits at the standard position relative to the dashboard. Correct for most standard steering wheel installations without a quick-release.
• Summary: If you are installing a quick-release hub between the hub adapter and the steering wheel, the long hub is typically the correct choice to maintain correct wheel position. If installing the steering wheel directly on the hub adapter without a quick-release, verify which hub depth is correct for your specific 911 variant and driving position before ordering.

• Note: Verify your specific 911 generation fitment with Momo's fitment guide or by contacting Straight Six Imports before ordering. Incorrect hub adapter fitment will prevent correct installation and is a safety risk.

What's Included:

• Momo long steering wheel hub adapter — Porsche 911 (MOML231)
• Centre nut and required mounting hardware
• Refer to Momo's product documentation for complete kit contents

Installation Notes:

• This is a safety-critical component — professional installation strongly recommended
• Airbag removal: Installing an aftermarket steering wheel and hub adapter requires removing the factory airbag from the steering column. Disconnect the vehicle's battery and wait at least 15 minutes before working on the airbag system to allow the airbag capacitor to discharge. Follow Porsche's airbag disarming procedure for your specific 911 generation before removal.
• Verify correct hub adapter fitment for your specific 911 generation before installation — incorrect fitment will prevent correct installation and is a safety risk
• Torque the hub adapter to the steering column to the manufacturer's specified torque — incorrect torque can cause the hub to come loose during driving
• Torque the steering wheel centre nut to the hub adapter manufacturer's specified torque after installing the steering wheel
• Verify correct steering wheel installation by checking for free rotation without binding and correct centring before driving
• If installing a quick-release hub between the hub adapter and the steering wheel, verify that the quick-release is correctly engaged and locked before driving

Why Momo?

Momo is an Italian steering wheel and wheel brand founded in 1964 — with over 60 years of motorsport heritage that includes equipping Ferrari, Lancia, Alfa Romeo, and many other factory race cars with their steering wheels and hub adapters. Momo's hub adapter lineup covers a wide range of Japanese, European, and North American performance vehicles — manufactured in Italy to the quality standards that the brand's motorsport heritage demands. For Porsche 911 owners who want a Momo hub adapter from the brand that invented the modern aftermarket steering wheel hub, Momo is the definitive choice.

Perfect For:

• Porsche 911 owners installing a Momo aftermarket steering wheel who need the correct long hub adapter for their specific 911 generation and installation configuration
• 911 builds where a quick-release hub will be installed between the hub adapter and the steering wheel — the long hub provides the additional depth offset needed to maintain correct wheel position with a quick-release added
• Track day and performance 911 builds where an aftermarket Momo steering wheel is part of a driver-focused interior upgrade

Important Notes: Safety-critical component — professional installation strongly recommended. Verify correct fitment for your specific Porsche 911 generation before ordering — multiple 911 generations have different steering column specifications. Airbag removal required — disconnect battery and follow Porsche's airbag disarming procedure. Torque all fasteners to specified values. If using a quick-release, verify correct engagement before driving.
