FAQs
Is Stage 3 a bolt-on-only kit?
No. Stage 3 should be treated as a build path with tune, waterbox, SuperCooler, fuel, and driveline review.
Can I buy Stage 3 before Stage 2?
You can plan the path at any time, but Stage 3 assumes the supporting Stage 2 foundation plus waterbox and SuperCooler are handled.
Who should install Stage 3?
Use an experienced installer or tuner familiar with higher-output 1630 ACE builds.
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 confirm my exact model?
Yes. Use your exact year, model, and engine when ordering so the GT40 team can confirm the correct fitment path.
