MPI-QR-RX-03: The Ultimate PATENTED Quick-Release Solution
The MPI-QR-RX-03 redefines quick-release technology, offering unmatched durability, PATENTED DESIGN precision, and performance. Widely adopted by the majority of INDYCAR teams during the 2024 season, this cutting-edge this cutting-edge system is designed with a 3 x 50.8mm bolt pattern M5 and a bolt/weld-on column male pin, making it the preferred choice for single-seater applications. This versatile mounting system ensures compatibility with a wide range of professional motorsport setups.
At its core, the RX03 features an innovative three-dowel pin locking mechanism that surpasses industry standards, ensuring virtually zero play for a secure, one-directional, smooth steering wheel attachment. Its push-on mechanism eliminates the need for collar activation, enabling quick and hassle-free installation. The self-centering one-position design with a six-faced, spline-less inner pin ensures the wheel is always positioned correctly, making ON/OFF steering wheel operation during driver changes both quick and mistake-free.
Safety is enhanced by an orange visual marker, providing immediate confirmation of proper engagement for both drivers and crew. The ultra-lightweight Featherlite body, weighing just 199 grams, optimizes performance without compromising strength. Designed to address common issues in competitor systems, the RX03 eliminates seize-up challenges often associated with Krontec quick releases and offers greater longevity with significantly less free play compared to SPA QR systems.
The RX03’s advanced design incorporates four distinct engagement points:
- Spline tip into body base for foundational stability.
- Three dowel pins into ramp faces for enhanced locking.
- PIN base and body mouth for added security.
- Pin Tabs and notches for precise alignment.
These features achieve near-zero play without the risk of seizing, while the tapered column side spline-less pin ensures smooth engagement and release, making steering wheel removal during endurance driver changes efficient and mistake-free, even in high-pressure situations.
Tested and approved to SFI standards, the RX03 meets the highest safety requirements for professional motorsports.
With its robust construction, innovative features, and proven performance, the MPI-QR-RX-03 stands as the ultimate choice for the most demanding motorsport applications.
