BRIDE RK Super Seat Rail

The BRIDE Super Seat Rail RK Type is a Japanese-manufactured reclining seat rail, designed for the BRIDE reclining and comfort seat lineup alongside a broad range of RECARO, SPARCO, and other aftermarket seat models. With mounting dimensions of 260mm in length (25mm + 235mm) and 405mm in breadth, the RK Type shares its dimensional footprint and seat compatibility range with both the RO Type and RB Type. For BRIDE seats, the RK Type supports the GIAS series, STRADIA series, edirb 023, edirb 033, CUGA series, VORGA series, BRIX2, ERGO2, XAX2, and PROS. For RECARO seats, it is compatible with the SR series and L series. Additional compatibility covers GULL and D&W seats. With the use of an import side stay, the rail extends to the RECARO SPG-N and SPARCO CORSA, REVII, PRO2000, and EVO, as well as any other seat that falls within the stated mounting dimensions.

Utilizes Sliders Made By Faurecia Exclusively For BRIDE

• BRIDE has partnered with Faurecia (France), one of the top mechanical parts suppliers in the world, to source exclusive components for their BRIDE super seat rail – such as sliders which are an essential part
• The sliders, which have an upper rail with a thickness of 2.0mm and a lower rail at 2.3mm in width, are equipped to lock on both the left and right sides; they do not make any noise when operating due to their superior strength and durability. The distance between each slide is 10 mm for 220 mm total travel amounting up or down.

ASEA-Approved High Quality & Peace of Mind

• The super seat rail is an item that has been approved by ASEA, a prestigious organization in the industry comprising motorsports companies, manufacturers and sellers of tuning parts who are all based in Japan. It has met the high standards set forth by this esteemed association.

Frequently Asked Questions

• What seats is the BRIDE Super Seat Rail RK Type compatible with? Without additional hardware, the RK Type is compatible with BRIDE GIAS series, STRADIA series, edirb 023, edirb 033, CUGA series, VORGA series, BRIX2, ERGO2, XAX2, and PROS; RECARO SR series and L series; and GULL and D&W seats. With the use of an import side stay, compatibility extends to the RECARO SPG-N and SPARCO CORSA, REVII, PRO2000, and EVO, as well as any other seat within the 260mm x 405mm mounting dimensions.
• How does the RK Type differ from the RO Type and RB Type? All three rails share the same mounting dimensions of 260mm (25mm + 235mm) x 405mm and the same seat compatibility range, including the same import side stay requirements and the same GIAS and STRADIA LR type advisory. The distinction between them is price and construction approach. The RO Type is priced at JPY 29,700, the RK Type at JPY 35,200, and the RB Type at JPY 40,700. Buyers should confirm with Bulletproof Automotive which construction approach is most appropriate for their specific vehicle and application before choosing between the three.
• Should I use the RK Type or the LR Type for a BRIDE GIAS or STRADIA series seat? This depends on your specific vehicle. For vehicle models where a dedicated LR type rail is available, BRIDE recommends using the LR type when fitting a reclining LOW MAX series seat such as the GIAS or STRADIA series. The RK Type is compatible with these seats but should only be used in vehicles where no dedicated LR type rail exists. Confirm whether an LR type rail is available for your vehicle before purchasing the RK Type for use with these seats.
• Will the RK Type lower the seat position in my vehicle? Not necessarily. Depending on the vehicle, the seat position may not be lower after installation. Buyers for whom achieving a lower seat position is a priority should confirm the position drop the RK Type delivers for their specific vehicle before purchasing.
• Do I need an import side stay to fit a SPARCO or RECARO SPG-N seat with the RK Type? Yes. The RECARO SPG-N and SPARCO CORSA, REVII, PRO2000, and EVO require an import side stay to be used alongside the RK Type. Without the import side stay, these seats are not compatible. Confirm availability of the appropriate import side stay before purchasing if fitting any of these seats.
• Is the RK Type compatible with BRIDE performance fixed bucket seats? No. The RK Type is designed for reclining and comfort seat models. BRIDE performance fixed bucket seats such as the ZIEG IV, ZETA IV, and XERO series use different mounting dimensions and require the appropriate performance rail such as the FO Type, FG Type, or equivalent within the BRIDE performance rail range.
• Is the BRIDE Super Seat Rail RK Type made in Japan? Yes. The RK Type is manufactured in Japan to BRIDE’s quality and fitment standards, consistent with the domestic production approach applied across the BRIDE seat and rail lineup.
