Our previous manufacture has now discontinued this item. A new design is in production but no production ETA is currently available for out of stock rails.
These seat rails are a proper, bolt in solution to fitting a side-mounted bucket seat while retaining adjustability. They are constructed using sliding rails, so can be adjusted forwards and backwards with the handle. They also have a selection of mounting holes to allow the seat to be mounted at different heights and angles.
These are super low seat frames, the seat actually sits in between each rail not on top. They are adjustable so allow varying width bucket seats to be mounted up to about 41.5cm's between bolt hole to bolt hole (The width of the base of the seat). It may be possible to fit even larger seats, but some 'massaging' of the frames may be required.
We currently only have Skyline Left available.
