Product Description

The NRG SRK-121H is a vehicle-specific short hub adapter engineered for select Toyota and Lexus platforms, providing a clean, solid mounting point between the OEM steering shaft and an NRG quick release unit. Like all hubs in NRG's iconic short hub lineup, the SRK-121H is built around a single guiding principle: the shortest possible hub profile that still passes horn and turn signal wiring through to the quick release, keeping the aftermarket steering wheel positioned at or very near the factory location. This preserves natural driver ergonomics while enabling the full quick release and removable steering wheel setup.

Machined as a single piece from aircraft-grade 6061 aluminum and finished with a durable black anodize coating, the SRK-121H delivers a rigid, play-free connection between the steering column and the quick release. Its one-piece construction is a deliberate advantage over multi-piece assemblies - there are no joints to loosen over time, and no flex to introduce imprecision into steering feedback. The 6x70mm bolt pattern on the top face is compatible with all standard NRG quick release units (Gen 2.0, 2.5, and 2.8 series) as well as most aftermarket 6-bolt steering wheels. This hub is protected under US Patent US7527293B1 along with the rest of the NRG short hub family.

The SRK-121H fits the 1994-2005 Toyota Celica, 1985-1990 Toyota Land Cruiser, 1986-1993 Toyota Supra, 1991-2004 Lexus GS series (GS300, GS400, GS430), and the 1994-2000 Lexus LS400. It is not compatible with the NRG Thin Quick Release or Quick Tilt system, and installation will disable factory SRS airbag and cruise control systems. A horn button is not included and must be sourced separately for use with a quick release. Professional installation is strongly recommended.
