A Planted Technology seat bracket for the Oldsmobile Alero, 1999 to 2004. Part number SB148.
The last Oldsmobile. General Motors closed the brand in 2004 after a hundred and seven years, and the Alero was the final car out of the door.
Which is the practical point
Nobody has made an Alero part since. There is no aftermarket, no new old stock worth speaking of, and the supply is whatever is left in scrapyards. That makes a bolt in bracket that needs nothing fabricated worth considerably more here than on a car with alternatives, and it makes keeping the original seats whole genuinely important.
Store them and their fixings somewhere dry and label them.
Related cars
It shares a platform with the Pontiac Grand Am, which takes SB147. If you are hunting mechanical parts, that is where to look, because there are more of them about.
Practical
Twenty five years old and never expensive. Get the carpet up and check the metal before you spend.
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 Oldsmobile Alero (1999-2004). 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.
