ultramindz Starter for Chevrolet Silverado Tahoe Suburban Avalanche Express Trailblazer 2003-2008 4.8/5.3L PMGR 9-tooth 12V 1.1 kW

The ultramindz 12V PMGR starter is a brand-new direct-replacement starter engineered to fit selected Chevy V8 trucks and vans (4.8L & 5.3L) from the 2003–2008 model years.

This replacement starter supplies the same mounting pattern, tooth count and rotation as factory units so you can restore reliable cranking on compatible Chevrolet vehicles. Manufactured new (not remanufactured), the unit is rated at 1.1 kW, spins clockwise (CW) and uses a 9-tooth pinion—specifications that match many GM small-block V8 applications. It suits a wide set of models including Silverado, Tahoe, Suburban, Avalanche, Express and Trailblazer family vehicles within the listed years and engine sizes.

How does this starter match factory specifications?

The ultramindz starter mirrors key original-equipment attributes so installation is straightforward when the vehicle application matches. It provides the standard 12V system compatibility and a 1.1 kW motor output with clockwise rotation and a 9-tooth pinion gear.

• Starter type: PMGR (permanent magnet gear reduction) for efficient torque delivery.
• Voltage: 12V, rated motor power: 1.1 kW for consistent cranking.
• Rotation: clockwise (CW) and tooth count: 9 to match original pinion engagement.
• Delivered new (not remanufactured) to avoid worn core components.

Will this starter replace my OEM part number?

Yes — it’s intended as a direct aftermarket substitute for numerous GM part numbers and legacy aftermarket references. Check your vehicle’s original starter numbers to confirm compatibility before ordering.

• Cross-references include common OEM and aftermarket numbers such as 12568051 and 89017631 among many others.
• Also listed to replace legacy references (e.g., 6494, 8000016, 89018123, 12604477).
• Verify your existing starter’s connector, mounting, and tooth count to ensure a match.

Installation requires mechanical skill: this product is intended for professional or experienced installers. Incorrect installation can damage the starter, flywheel ring gear, or vehicle electrical system, so we strongly recommend a qualified mechanic handle the fitment and wiring connections.
