Bride M037RO RO-Type Super Seat Rail Bottom Mount

The Bride M037RO is an RO-Type Super Seat Rail, a bottom-mount sliding rail designed to provide a precise, high-rigidity foundation for a wide range of reclining aftermarket sport seats. Made in Japan, this rail is part of Bride's ASEA-approved Super Seat Rail lineup — an industry safety standard set by motorsports companies and tuning parts manufacturers in Japan.

Bride handcrafts each seat rail by physically measuring full-scale vehicle frames to eliminate excess gaps in bolt holes and maximize fitment accuracy between the vehicle floor, rail, and seat. Sliders are sourced exclusively from Faurecia (France) and feature upper and lower rails at 2.0mm and 2.3mm thickness respectively, locking on both sides with a 10mm pitch and 220mm of slide travel for a rattle-free, secure fit.
