Will this fit with my existing fan and shroud?

Yes. This radiator is designed to work with your factory fan and shroud — no cooling system upgrades required unless you're running significantly higher power output.

Do I need new hoses or clamps?

Test-fit the radiator in your bay before assuming existing hose length and routing work. You may reuse your current hoses if they're in good condition and reach both inlet and outlet, but have replacements on hand just in case.

What's the actual cooling improvement over stock?

The extra row gives you more surface area for heat transfer, especially noticeable during sustained climbing or stop-and-go trail running. Real-world gains depend on your ambient temperature, load, and how hard you're pushing the engine.
