Radiator Stays - Billet Mounts for WRX, EVO, K20, S2000

What This Collection Covers

Fitment focused selection

Radiator stays secure the upper portion of the radiator while adding a clean finish to the engine bay. This collection includes billet aluminum stays, mounting brackets, inserts and vehicle specific hardware for popular sport compact and performance applications.

Billet Radiator Mounts

Secure cooling system support

A correctly matched radiator stay maintains the intended upper mounting position without loading the radiator or hose connections. Select the application specific bracket and inspect the lower mounts at the same time.

WRX and STI Cooling Details

Subaru specific fitment

WRX and STI stays in this collection cover several chassis generations. Check model year, turbocharger configuration, hood prop clearance and radiator type before choosing a color or finish.

Honda and Mitsubishi Applications

Sport compact engine bays

Civic, Integra, S2000 and Evolution owners can use an upgraded stay to refresh worn original hardware and coordinate the engine bay with other cooling upgrades.

Installation and Service

Protect the radiator core

Do not overtighten the mounting hardware. Verify that the radiator sits squarely on its lower cushions and that fans, shrouds and hoses have safe clearance.

Common Questions

How do I confirm fitment?

Match the exact year, make, model, trim, engine, drivetrain and the product notes before ordering.

Should I replace related wear items at the same time?

Inspect the surrounding components during service and replace worn seals, hardware or fluids when the application calls for them.

Can I install these parts at home?

Many jobs suit an experienced home technician with the right tools, service information and safe lifting equipment.

Why is vehicle fitment important?

Vehicle fitment determines dimensions, mounting points and specifications, so it is the best way to narrow the correct choice.

Do performance parts fit stock vehicles?

Some performance parts are direct replacements while others need supporting parts or tuning, so read each product listing carefully.

What should I check before installation?

Compare the new part with the removed component and verify the required hardware, gaskets, fluid and clearances.

Can I filter parts by vehicle?

Yes. Use the year, make, model, trim, engine and drivetrain filters to identify compatible products.

When should I ask for fitment help?

Ask before ordering if the vehicle has an engine swap, transmission conversion, aftermarket brakes or other major changes.

Are instructions included?

Instructions vary by manufacturer. Review the product page and factory service information before starting work.
