The SRP® Extension Keys expertly adjust pedal height to perfectly match your foot size and driving style, transforming your sim racing posture with superior ergonomics, comfort, and telemetry control.
This essential industrial-grade upgrade delivers a natural, efficient driving position that eliminates ankle fatigue and maximizes precision during intense endurance racing sessions.
Extension Keys shine for drivers with larger shoe sizes (EU 44 / US 10 / UK 9.5+), raising the pedal surface to eliminate excessive ankle flexion and perfect the heel-and-toe technique.
Drivers with smaller feet also benefit dramatically—easily lower the pedal height for optimal comfort and precise control over our high-pressure pneumatic cylinders.
100% 5-axis CNC machined from Aerospace Aluminum AL6061 with an extra-hard 28-micron anodized finish. These keys are engineered to deliver clean, professional integration without sacrificing a single millimeter of structural rigidity.
Available for 2- and 3-pedal configurations, adapting to any SRP® pedal set while maintaining the premium stealth look of your simulator cockpit.

A mobile-ready comparison of how SRP® dynamic air physics positions itself against traditional SimRacing technologies.
Rubber compression (Static resistance)
Linear & dead. Often described as "wooden".
High. Elastomers degrade and soften with heat/use.
Air dynamics do not fatigue. SRP maintains a perfect, temperature-independent feel for years.
Oil displacement (Organic feel)
Excellent initial bite and realistic pressure curve.
High risk of leaks. Requires messy fluid changes.
Zero mess. SRP replicates fluid physics using compressed air and industrial seals (No oil leaks, ever).
Electric Servomotor (Fully software driven)
Infinite customization, but can feel synthetic or artificial.
Extremely complex electronics and high software reliance.
Natural, organic physics at 1/3 of the cost. Mechanical tuning is intuitive and tool-free.
Dynamic Compressed Air (Industrial grade pistons)
Authentic exponential curve. Replicates a real master cylinder perfectly.
Zero. Rated for 3.5M kilometers. Industrial NBR Seals.
