A Planted Technology seat bracket for the Chevrolet HHR, 2006 to 2011. Part number SB325.
The HHR is the retro styled estate built on the same platform as the Chevrolet Cobalt, which takes SB225.
The HHR SS is the reason
General Motors put the turbocharged 2.0 Ecotec into it, with a limited slip differential and a proper manual gearbox, which made a retro shaped estate genuinely quick. It is one of the more unlikely performance cars of the period and it has a devoted following because of it.
The SS shares its running gear with the Cobalt SS, so if you are hunting mechanical parts, that is where to look.
What the shape gives you
Unusually for a car we make brackets for, the HHR is tall and boxy inside with genuinely good headroom. That is a real advantage: shell choice is less constrained than in a low coupe and a taller driver has options.
Side airbags are fitted. 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 HHR (2006-2011). 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.
