A Planted Technology seat bracket for the Toyota Tundra, second generation on the XK50 chassis, 2007 onwards. Part number SB308.
The first generation takes SB381.
The generation Toyota built a factory for
Toyota opened a plant in Texas specifically to build this Tundra and made it genuinely full size for the first time, with the 5.7 litre V8 that gave it credibility against the domestic trucks.
The TRD Pro version is the one set up for going quickly on rough ground rather than crawling, and it is where a supportive seat earns its keep. At speed on a broken surface the truck moves constantly and the standard bench or bucket lets you move with it.
What you are not doing
Sitting lower. The height is a large part of why you have a full size pickup, so the aim is being held rather than being low.
Trim
If it works or sees mud and water, ask us about neoprene rather than velour. Fabric absorbs everything and never recovers.
Handed, so order twice for a pair.
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 Tundra. 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.
