How does this starter match OEM specifications?

The unit is a Permanent Magnet Gear Reduction (PMGR) starter with clockwise rotation and a 12-tooth pinion, matching the physical and electrical characteristics of many factory starters. It replaces numerous OE part numbers so installation is typically bolt-in with no modification. Using a starter that matches rotation and tooth count prevents damage to the ring gear and ensures proper engagement.

• Voltage: 12V — compatible with standard automotive electrical systems
• Rotation: Clockwise (CW) to match factory orientation
• Teeth: 12-pinion teeth to align with stock flywheel/ring gear
• Type: PMGR gear reduction starter for improved torque and compact size

What durability and quality features does the Aeagle starter include?

Aeagle applies targeted testing and material choices to prolong the life of the starter drive gear and solenoid components. The starter gear is treated for improved wear resistance and anti-slip performance, reducing the chance of slippage during engagement and repeated starts. Components undergo performance checks to help ensure dependable cranking under typical operating conditions.

• Wear-resistant starter gear treatment for longer service life
• Anti-slip properties to maintain positive engagement at startup
• Manufacturing checks and bench testing to verify rotation and engagement
• Direct-replacement fit for simpler installation and fewer adapters

Which OE part numbers does this replace and why is that useful?

This starter lists many cross-reference numbers used by Ford and aftermarket suppliers, which simplifies identification during repairs. Matching a replacement to an OE part number helps guarantee correct physical fit, mounting, electrical connectors and gear alignment. If your original starter’s part number is on the cross-reference list, this Aeagle unit is intended as a like-for-like swap.

• Replaces common numbers like 6646, 410-14043 and SFD0024
• Also cross-references multiple Ford OEM codes starting with F81U-, F81Z- and YC3U-
• Cross-reference reduces risk of incorrect purchases and returns

Who this is for: This Aeagle Starter 6646 is for DIY mechanics, professional shops and fleet managers who need a cost-effective, direct-replacement starter for compatible Ford trucks and SUVs. It’s best suited for owners of late‑90s through mid‑2010s Ford vehicles with the listed engine sizes who want an OEM-style PMGR starter with verified rotation and tooth count. Before ordering, verify engine displacement and match the OE cross-reference numbers to ensure a trouble-free swap.
