Racetech RT4119W Racing Seat

The Racetech RT4119W takes the proven ergonomics of the 4100 series and adds a wider hip and rib area for bigger drivers or those who prefer a little more room without losing lateral support. It is a great option for powerful street based track cars, time attack builds and off road applications where comfort and control both matter.

Why we like the RT4119W

• Wider shell that actually fits larger drivers without feeling like you are sitting on top of the seat
• Tall shoulder and torso bolsters to keep you braced during high grip cornering
• Composite construction tuned for stiffness and durability in demanding environments
• Fire retardant upholstery with breathable panels to help manage heat on long days
• Side mount design compatible with Racetech alloy and steel brackets and most common sliders
• Generous harness openings for modern 6 and 7 point belts and HANS devices

Fitment and sizing

This listing covers the RT4119W wide shell. It is ideal for drivers who find typical fixed back seats too narrow at the hips or shoulders. As always, we recommend checking your hip and shoulder width measurements against the Racetech sizing chart before ordering.

Installation notes

The 4119W is side mounted and designed to work with Racetech side brackets and optional back mount hardware. Mock everything up with your preferred seating position, helmet and belts before final drilling and always have a qualified shop confirm your mounting solution for safety.
