2021-2026 Ford F-150 5.0L Whipple Stage 1 to Stage 1R Upgrade Kit

2021-2026 FORD F-150 5.0L
WHIPPLE STAGE 1 TO STAGE 1R UPGRADE KIT

The Whipple Stage 1 to Stage 1R Upgrade Kit is designed for 2021-2026 Ford F-150 5.0L owners who already have a compatible Whipple Stage 1 system and want to move up to Stage 1R without replacing the complete supercharger package. This upgrade adds the key fueling, boost, and calibration changes that separate Stage 1R from the standard Stage 1 configuration.

With 93 octane or higher, this upgrade is capable of adding up to an additional 40 horsepower and 15 lb-ft of torque under optimal conditions. The package includes a billet Whipple supercharger pulley for a 1 psi boost increase, a Bosch 55 lb high-flow fuel injector set, and the updated Stage 1R calibration needed to support the added output.

This is a parts-and-calibration upgrade intended for existing Whipple Stage 1 customers who want the stronger fueling capacity and higher performance associated with the Stage 1R configuration. It provides a straightforward bolt-on path to the next step in the Whipple F-150 lineup without requiring a complete hardware change.

The included calibration is supplied for reuse with the existing Tomahawk flash tool, provided the tool remains on the same VIN. That helps make this a cleaner upgrade path for current Whipple owners already running a compatible Stage 1 system.

Whipple Superchargers shipping & returns

• Limited warranty: a Whipple product suspected of being defective is returned under Whipple's returns procedure; Whipple inspects it and decides whether it is covered and whether to repair or replace it, then ships it back by ground service.
• Superchargers make unique sounds; noises Whipple considers normal for a supercharger are not covered.
• Kits that list a model year, vehicle model or VIN need those details with the order so the right calibration is built.
