The fuel filler lid is a highly visible body component on the R34 GT-R that must fit precisely and operate smoothly for both function and appearance. The genuine Nissan Quarter Panel Gas Lid Door (part number 78830-AA400), also available under the NISMO Heritage part number 78830-RHR40, is the factory fuel filler lid designed for the Nissan Skyline R34 GT-R. This lid mounts in the rear quarter panel and provides the correct seal, hinge alignment, and exterior finish surface for the fuel filler opening.
Original lids can become damaged from impact, corrosion, or repeated opening and closing, resulting in poor fit, misalignment, or an unfinished appearance. Replacing a worn or damaged unit with the genuine Nissan 78830-AA400 restores the correct panel fit and factory-style operation. Catalog sources confirm this lid is intended for the R34 GT-R (BNR34) and is also listed for other R34 Skyline models. The part is typically supplied unpainted so it can be color-matched to the vehicle.
Whether you are repairing collision damage, restoring a neglected body panel, or completing a high-quality R34 GT-R restoration, this OEM fuel lid delivers the authentic fit and finish required. At Terra Firma Automotive, we supply this genuine Nissan / NISMO Heritage Gas Lid Door for R34 GT-R owners who demand correct-fit body components.
