Keeping an eye on your diesel engine’s RPM is essential whether you’re pulling a trailer, putting the truck to work, or just cruising day to day. This ISSPRO gauge delivers accurate, easy to read RPM information that your factory instrument cluster may lack or can’t be trusted to show precisely. With clear insight into engine speed, you can make smarter shift decisions, stay in the ideal power range, minimize drivetrain stress, and avoid damaging conditions. It’s a simple upgrade that helps your engine perform at its best in any driving situation.

IMPORTANT NOTES:

• 92 And Above Option gauge is sold with a bracket, wiring harness, and R8913 filter which allows you tie the tach into the 92 and above Dodge ECM
