HOT CAMS Stage 1 Exhaust Camshaft is a dyno-proven performance upgrade built to deliver noticeably stronger low-end and low-to-mid RPM torque with improved throttle response. If you want your engine to pull harder earlier in the rev range (without turning the build into a complicated project), this drop-in cam is designed to make that happen with OEM-like fitment.
It helps improve real-world rideability by increasing torque where you use it most, making acceleration feel more immediate and controllable. Fuel-injection remapping is not required (though it may further refine overall performance), so you can upgrade efficiently while keeping the setup straightforward.
Key features:
✅ Stage 1 profile designed for low-end torque and stronger low–mid RPM pull
✅ 5%–10% power gain (application dependent) with improved throttle response
✅ CNC-machined 8620 billet steel, case-hardened for an exact lobe profile and fit
Benefits of use:
🔹 Stronger torque delivery for more responsive acceleration and better drive out of corners
🔹 Drop-in design helps reduce installation complexity and keeps maintenance practical
🔹 Proven development (designed and dyno tested in the USA) for confidence in performance
