Description
You can rely on the XDP HD Gear Reduction Starter (New) Wrinkle Black XD251 to get your 2001-2019 GM 6.6L Duramax running in the most extreme environments. XDP's HD Gear Reduction Starters are faster, stronger, and more durable than your factory starter. This gives you the ability to turn over even the most aggressive diesel engines.
XDP's HD Gear Reduction Starters feature a faster motor that draws less amperage, and is more efficient. The Gear Reduction Design produces more torque than a factory unit. Each starter comes pre-tested, ready for installation and features a durable "Wrinkle Black" finish for corrosion resistance and aesthetics.
Features:
- HD Gear Reduction Design
- Wrinkle Black Finish
- Increased Durability
Specifications:
- 3.0 HP
- 2.2 KW
- 200 Ft-Lbs. Torque
- 3.75:1 Gear Reduction
Tech Notes:
Depending on the conditions, a starter can pull up to 500 amps. These levels of amperage stress ALL components in the circuit including cables, terminals, batteries, and more. Problems with these components can be difficult to diagnose as they appear fine at rest and under a light load, but generate high resistance under heavy amperage draws. This results in low voltage to the starter while cranking, causing heavier amperage draw, and increased heat leading to starter failure. Batteries, cables and additional components should be checked and serviced regularly. Voltage measured at the starter during cranking should always be above 11V DC. Starter heat shields are not required, but are an excellent idea for heat protection.

Chris (Gilbert, Arizona) | December 3rd, 2022
This starter worked OK for the first few weeks. Now it intermittently makes a grinding sound when engaging or disengaging from the flywheel. It starts like a son of a gun so I would be very happy if not for the unnerving grinding. I called customer service to report the problem and get a warranty replacement. They said a tech would call me right back. No call. Later I found an email from a tech suggesting the problem is likely related to my flywheel. Come on! The OEM starter never made any strange noises and the flywheel was pristine when this starter was installed. Do a little googling of this issue and it is always the solenoid. I responded to the email and never received a response. This is CRAP customer service. Just send me a warranty replacement or a new solenoid if you prefer. Either way it is costing me a lot of time and slowly damaging my flywheel. NOT impressed!
