A Planted Technology seat bracket for the Nissan Frontier, second generation on the D40 chassis, 2005 to 2021. Part number SB407.
The D40 is the Navara in this country. Sixteen years on one bracket, because Nissan changed remarkably little underneath across that run.
The chassis rust recall is worth knowing about
D40 Navaras became notorious in the UK for chassis corrosion, to the point where Nissan offered goodwill settlements and a great many were written off rather than repaired. If you are buying one to build, have the chassis properly inspected before you spend a penny on the interior.
That is not a seat problem, but it is the single most useful thing anyone can tell you about a D40, and a bracket can only feed seat load into sound structure.
What the seat change is for
Support on rough ground over a long day. The height is part of why you have a pickup.
Later cars have side airbags. Tell us the year and specification.
Ask us about neoprene trim if it works for a living.
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 Frontier (2nd Generation). 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.
