A Planted Technology seat bracket for the Mercedes G-Class on the W463 chassis. Part number SB400.
Check the year with us before ordering
Our listing title and our attribute data give two different year ranges for this bracket, and rather than pick one and hope, send us the registration or the model year. We are correcting the listing.
It matters more here than on most vehicles: the W463 ran from 1990 to 2018 with continuous revisions, which is one of the longest production runs of any modern vehicle.
What a G-Class is
Body on frame with three locking differentials, originally built for the Shah of Iran and then for the Argentine army before Mercedes sold it to civilians. It has barely changed in principle in forty years.
The seat decision is about being held on rough ground, not sitting lower. The height is a large part of what the vehicle is.
Practical
Ask us about neoprene trim if it sees water and mud. Later cars have side airbags and powered adjustment, so 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 made for the Mercedes G-Class (1992-2022). 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.
