A Planted Technology seat bracket for the Toyota Prius, first generation on the XW10 chassis, 1997 to 2003. Part number SB370.
We list all four generations: this, XW20, XW30 and XW50.
The first mass produced hybrid, and there are not many left
Toyota launched the XW10 in Japan in 1997, and it is genuinely historically significant regardless of what anyone thinks of the car. Very few survive, because they were cheap for years and the battery packs eventually made them uneconomic to keep.
So this is an unusual bracket to be ordering, and it is worth telling us what the car is for, because the answer changes what we would suggest.
One warning
A hybrid carries high voltage cabling. On a car this old the insulation and connectors are twenty five years into their life. If you are not entirely certain what runs under the seats, have the work done by someone who is.
Ask us about padded options if the car does long days.
Have you written anything about this exact product?
Yes, we have covered this exact product: Lexus Planted Technology Frames Updated For 2026, and Customer Car: Subaru Impreza With Corbeau RRS Seats and Planted Technology Brackets. That is first-hand coverage from our own builds and showroom, not brochure copy.
Will this fit my car?
This frame is made for the Toyota Prius. Chassis code and years matter more than the badge, as floor pans change between generations, so if your car sits near a changeover year, send us the registration and we will confirm before you order.
Which seats does it take?
Check the bolt pattern in the specification against your seat. The Compatible seats tab above lists what bolts straight on. If your seat is not listed, tell us what you run and we will confirm the fit.
Do I keep fore-and-aft adjustment?
Only with a sliding runner between the frame and the seat, which is a separate part on Planted frames. If more than one person drives the car, budget for the runner. Our guide to sliding runners explains the options and widths.
Is this for the driver or passenger side?
Both sides are available on this listing, pick driver or passenger side at the point of order (sides listed are for right-hand-drive cars). Left-hand-drive car? Ask us, as the sides swap over and availability varies by model.
