A Planted Technology seat bracket for the Mazda 3, first generation. Part number SB374.

The BK, built 2003 to 2009. We list four Mazda 3 brackets across the model’s life: this, SB260, SB264 for the third generation and SB404 for the fourth. Send us the registration and we will name the one your car takes.

The first 3 is Ford underneath

Built on the C1 platform Mazda developed with Ford during their partnership, shared with the Focus Mk2 and the Volvo C30. That is why the chassis was so much better than the class expected and why parts cross over more widely than the badge suggests.

The MPS

If yours is a Mazdaspeed 3 or 3 MPS, that has its own listing under SB183.

Practical

Twenty years old now. Get the carpet up and check the metal round the mounting points before you spend.

Side airbags are fitted. Tell us the specification.

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 car-specific, so match the vehicle in the product name to your exact car and generation. If you are unsure, 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.

Availability

Planted brackets are special order from the USA

We bring a batch over roughly every 3 to 5 weeks. Everything in each batch is pre-sold against a customer order, so the sooner your order is in, the sooner it ships.

Need it faster? Ask us before you order. We occasionally hold overstock of the popular models, and we can tell you what is on the shelf.

Special order, so non-returnable once shipped

Once your bracket has shipped from the USA for your order, our non-returnable policy applies. It was bought in for you specifically.

That makes it worth getting right first time. Send us your car and the seat you are fitting and we will confirm the correct bracket before you buy.
