RT4119 Complete Race Seat Installation Package

The Racetech RT4119 Complete Race Seat Installation Package delivers a professional-grade seating and safety solution trusted by top motorsport teams worldwide. This all-in-one bundle includes a Racetech RT4119 FIA 8855-1999–approved race seat, durable steel side-mount brackets, and a Racetech FIA-approved Pro International 6-point harness—giving you everything required for a secure, competition-ready installation.

Derived from the acclaimed 129 Series, the RT4119 seat retains the same proven ergonomics, driver support, and race-winning geometry while offering a lighter and more cost-effective design. Racers can choose from four sizes—standard, wide, tall, and wide-tall—to achieve the perfect fit.

The RT4119 is widely used in professional national and international motorsport, including drag racing, no-prep builds, door cars, road racing, and time attack. It is factory-installed in the Ford Mustang Cobra Jet and Dodge Challenger Drag Pak programs and meets NHRA requirements for the current FX (Factory X) class.

With premium build quality, and FIA certification, the RT4119 package offers unmatched value and performance for drivers who demand safety, comfort, and precision in one complete installation kit.
