aurosant Starter for 1999–2005 GM 6.0L V8 Trucks & SUVs — PMGR 1.6 kW, 11-Tooth 12V Direct-Fit Replacement

This aurosant starter is a direct-fit replacement for many 6.0L V8 GM trucks and SUVs from 1999–2005, delivering 1.6 kW PMGR starting power with an 11-tooth pinion and 12V supply.

If your Chevy, GMC or Cadillac with a 6.0L V8 is showing slow cranking or won’t spin over, this aftermarket starter is built as a bolt-in substitute for specified OE numbers and vehicle years. It’s engineered as a permanent magnet gear reduction (PMGR) starter designed to match the original rotation direction and gear tooth count, so mechanics and DIYers can swap it without modifying engine or wiring layouts. Below you’ll find fitment details, technical specs, installation pointers and who should consider this unit.

Which vehicles will this starter fit?

This starter is compatible with a range of GM models that used the 6.0L V8 between roughly 1999 and 2005. Always cross-check the listed part numbers and your vehicle’s year, engine and VIN to confirm correct fitment before purchase. If your truck or SUV appears in the OEM number list below, this unit was made to match that factory configuration.

• Chevrolet: Silverado 1500 HD, 1500 (selected years), 2500, 3500, Suburban 2500 (2000–2005)
• Chevrolet Express: 2500 and 3500 (2003–2005)
• GMC: Sierra 1500 HD, 2500, 3500, Savana 2500 (2000–2005 range depending on model)
• Cadillac: Escalade and Escalade EXT (2002–2005) — confirm engine code and build year

What technical specifications does this starter include?

The unit is a PMGR design rated at approximately 1.6 kilowatts and operates on a 12-volt system. It uses clockwise rotation, an 11-tooth pinion and is intended to replace several OE reference numbers so it matches factory engagement and electrical characteristics.

• Power output: ~1.6 kW
• Design: PMGR (permanent magnet gear reduction)
• Voltage: 12V, rotation: clockwise (CW)
• Gear: 11 teeth pinion for correct mesh and engagement

Which OE numbers does this replace and why that matters?

This aftermarket starter lists many original equipment numbers to help identify compatibility with existing factory parts. Matching your vehicle’s original part number to one of these replacements reduces the chance of ordering the wrong component and ensures the starter will bolt up and engage like the stock unit.

• Common cross-reference numbers include: 323-1444, 323-1485, 336-1932 and 10465550 among others
• Also compatible with part codes such as SDR0097, STR-2606 and legacy numbers like 6492
• Use your vehicle’s current starter part number or VIN-based lookup to confirm a match

How easy is installation and what should I check before swapping?

Installation is straightforward for someone familiar with starter replacement: disconnect the battery, unbolt wiring and mounting fasteners, remove the old starter and reverse the steps for the new unit. Check electrical connections, ground points and clearance for the pinion to ensure reliable operation after installation.

• Disconnect the negative battery cable before starting
• Inspect battery condition and cable terminals for corrosion or high resistance
• Confirm starter alignment and torque mounting bolts to factory specs
• Test starter engagement before fully reassembling underbody shields or heat shields

Who is this for: This aurosant starter is intended for owners, mechanics and fleet technicians servicing late‑1990s to mid‑2000s GM full‑size trucks and SUVs with the 6.0L V8 who need a direct-fit replacement. It’s suitable for those who require OE cross-reference compatibility, a PMGR gear reduction design for reliable cranking, and a straightforward bolt-in swap. If you’re unsure about fitment, compare the original starter’s part number to the replacement list or reach out to customer support before ordering.
