A Planted Technology seat bracket for the Nissan Hardbody pickup, two door, 1985 to 1997. Part number SB336.
The D21, sold here as the Nissan Pickup and later the Navara. The 720 before it takes SB257.
Two door is the qualifier, so check what you have.
The name is a marketing term that stuck
Nissan called it Hardbody in America because of the double wall bed construction, and the name outlived the marketing entirely. In this country nobody used it, which is why UK owners searching for a D21 bracket may not think to look here.
If you have a UK Pickup or early Navara of these years, send us the registration and we will confirm.
Why these get seated
Usually because the original has collapsed. Thirty to forty years of work leaves nothing in the base, and a competition shell on a bolt in bracket is a straight upgrade rather than a motorsport modification.
Ask us about neoprene if the truck still works. Get the mat up and check the floor first.
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 Nissan Hardbody Pickup (2 Door). 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.
