XDP Gear Reduction Starter 08-10 Ford 6.4L Powerstroke Wrinkle Black XD256

You can rely on the XDP Wrinkle Black HD Gear Reduction Starter XD256 to get your 2008-2010 Ford 6.4L Powerstroke 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 more efficient motor that is quicker, and draws less amperage. The Gear Reduction Design produces more torque than a factory unit, at about a third of the size. This not only reduces weight, but also makes a more compact design for easier installation. 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 1-Year Warranty Specifications: 4.0 HP 3.0 KW 275 Ft-Lbs. Torque 4.75:1 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. This starter is not intended for use on a 6.0L Powerstroke. Using a 6.4L starter to "pgrade the 6.0L unit can often result in premature failure due to excessive amperage draw. Starter failure due to improper application is not covered by warranty

Sustainability Score

42%

Full Send Diesel shows limited transparency regarding their environmental practices and supply chain management. While they offer some eco-friendly alternatives in their product line, their core business model promotes high-emission vehicle modifications. The company lacks clear sustainability goals and reporting. Their packaging and shipping practices show room for improvement, and there's minimal information about their manufacturing partners' labor conditions.
