A Planted Technology seat bracket for the Chevrolet Caprice, 2011 to 2017. Part number SB273.
This Caprice is the Holden Commodore, built in Australia and sold in North America almost entirely as a police vehicle. It is the same family as the Pontiac G8 and the Vauxhall VXR8.
Police specification changes what you are working with
These were not sold to the public. A retired one arrives with the interior already stripped about, holes drilled for equipment, and a driver’s seat that has been sat in by shift workers for a decade with a duty belt on. Column and console areas are often modified too.
So look properly at what is actually there before ordering, rather than assuming a standard interior. Send us a photograph under the seat if anything looks unusual.
What is underneath
A proper rear wheel drive chassis with a V8 in most, which is why people buy them cheap at auction and build them.
Tell us about airbags and seat wiring before anything comes out. Handed, so order twice for a pair.
Have you written anything about this exact product?
Yes, we have covered this exact product: Planted Technology Chevrolet Sub-Frames: Ready For The 2025 Racing Season. 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 Chevrolet Caprice (2011-2017). 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.
