FAQs
Is there a single boxed Stage 2 kit?
This is currently a build path. Confirm parts and fitment before ordering.
Does Stage 2 require a tune?
Tune review is recommended because setup varies across older 4-TEC hulls.
Should older machines be inspected first?
Yes. Confirm supercharger, hoses, and maintenance state before adding power.
How fast does the kit ship?
In-stock GT40 parts normally ship from the current GT40 fulfillment queue. Check the product page before checkout for live availability.
Will this affect my factory warranty?
Any performance modification can affect factory warranty coverage. Confirm with your dealer and installer before modifying a new craft.
Can GT40 help verify my exact model?
Yes. Use your exact year, model, and engine when ordering so the GT40 team can confirm the correct fitment path.
