Brackets

Brackets: the mounts that hold your build together

A bracket does one quiet job well - it locates a component and holds it against vibration, torque and heat so nothing walks loose. That covers engine and transmission mounts that tie the powerplant to the chassis, alternator and AC relocation kits that clear an intake or turbo setup, chassis braces that stop unwanted movement, and hardware that secures a nitrous bottle. If you have relocated a compressor, swapped an engine, or added a bottle and need it held down properly, a bracket is the part that makes it stay put.

ThreePiece stocks 82 brackets across 20 brands. The biggest ranges come from Vibrant (19), Innovative Mounts (12), Perrin Performance (11) and Torque Solution (10), with Radium Engineering, Nitrous Express, Turbosmart, S&S Cycle and others filling out the rest. Prices currently run from $25 to $542 for what is in stock - that is the live range, not a fixed price. Fitment data is listed on 32 of these parts, with the top makes being Subaru, Honda, Harley-Davidson, Chevrolet, Acura and Mitsubishi, over a listed year span of 1955 to 2025.

How to choose the right bracket

Start with the job. For an engine or trans swap, motor mounts drive how much vibration reaches the cabin - a stiffer bushing transmits more but holds the engine tighter under load. The Innovative K-Series steel mounts with 75A bushings for the 06-11 Civic sit at the top of the range at $542.50; read the note - they are not for the K24 trans. For accessory clearance, a relocation kit like the Torque Solution alternator relocation bracket for the 02-14 WRX or the Innovative B-Series AC conversion bracket for the 88-91 Civic/CRX moves a component out of the way of your intake or swap.

For chassis control, the Torque Solution pitch stop brace for the 2015+ WRX/STI limits driveline rock. If you run nitrous, match the bracket to your bottle size and how you want it mounted - the Nitrous Express billet bracket for 10lb/15lb bottles includes floor mounts, while the stand-up bar-mount version for a 10lb bottle suits a roll bar. Check the exact vehicle, year and bottle size in each listing before you order.

What else you need with it

Brackets rarely go in alone. Relocating an alternator or AC often means new fittings and adapters to reroute lines, and swap work frequently pairs with fresh gasket kits and head gaskets. Nitrous and relocation builds are a good time to check your fuel pumps and radiators. Browse everything in the Engine Components section to round out the job.

Fitment and ordering

Not every bracket lists fitment, and several are vehicle-specific, so confirm your make, model and year against the listing. If you are unsure, call fitment help at 813-535-5801 or reach us through contact us. Every order ships free, and Affirm and Katapult financing is available at checkout.
