A Planted Technology seat bracket for the VW Jetta Mk3. Part number SB026-4878.
The suffix places this within the SB026 family, which covers the Mk3 Golf, GTI and Jetta on a shared floorpan, alongside a Golf specific version under SB026-4879.
Three listings on one design. Send us the registration and we will tell you which one your car takes.
The Jetta is not just a Golf with a boot here
In North America the Mk3 Jetta outsold the Golf substantially and got specifications the hatchback did not, including the VR6 in a body that suited it rather better. If your car is a North American import, send us the chassis number rather than the registration.
The VR6
Narrow angle six cylinder in a front wheel drive saloon, which was an odd thing to build and is exactly why people still build them. It is heavy over the front axle and the standard seat gives you nothing to brace against.
Practical
Mk3s rust round the floors and few have been cherished. Get the carpet up 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 VW Jetta MK3. 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.
