Adjust The Throttle Sensitivity. Good maintenance habits are key to maintaining your Silverado’s throttle sensitivity. But that doesn’t mean you can’t go a step beyond in improving mileage and eliminating the delay. The JMS PedalMAX Terrain Drive by Wire Throttle Enhancement Device allows you to increase and reduce the throttle sensitivity to get the best performance out of your vehicle on the street and in unfavorable traction conditions.
High-Quality Construction. The JMS PedalMAX Terrain is an off-road-ready aftermarket upgrade. Not only does it help adjust the throttle response for different terrain types, but it’s also designed to withstand the rigors of extreme weather and trail conditions. This reliable throttle enhancer delivers long service life when properly maintained and used.
Save Your Settings. Using the knob on the JMS PedalMAX Terrain controller, you can adjust the pedal sensitivity at various throttle levels. Once you’re happy with a particular response, unplug the device to save that setting. You’ll still be able to make on-the-fly adjustments.
Straightforward Installation. Installing the JMS PedalMAX Terrain can be tricky but doesn’t require professional help or adaptation. The device comes with vehicle-specific mounting hardware and connectors compatible with stock components. Note that the device is calibrated for maximum pedal sensitivity out of the box.
Limited Warranty. JMS covers the PedalMAX Terrain with a standard limited 1-year warranty.
Application. The JMS PedalMAX Terrain Drive by Wire Throttle Enhancement device has excellent fitment on the 2020-2026 Chevrolet Silverado 2500 HD models.
