How does this starter match my original part number?

The ultramindz starter is designed to replace an extensive range of OEM and aftermarket part numbers; cross-referencing ensures you get the correct swap. If your old starter lists one of the referenced numbers, this unit provides the same gear count, rotation and electrical ratings needed for proper engagement and cranking.

• Replaces popular references like 12568051 and 89017631 among other OEM codes.
• Matches specifications: 12V, PMGR type, 1.1 kW power, clockwise rotation, 9 teeth.
• All-new construction—no remanufactured cores—so internal wear is not present.

What should I know before installing this starter?

Installation requires mechanical experience and the right tools; battery disconnection and proper torque on mounting bolts are essential for safety and electrical integrity. Because fitment depends on engine and chassis details, verify the unit against your vehicle’s service manual or consult a professional mechanic for installation.

• Disconnect the negative battery terminal before removal/installation.
• Ensure mating surfaces are clean and bolts are torqued to factory specs.
• Professional installation is highly recommended to prevent damage.

What physical and electrical specs matter for replacement?

This starter uses a gear reduction design to increase torque while keeping size and current draw reasonable; make sure these values match your vehicle’s starter requirements. Confirm rotation direction, tooth count and voltage to avoid engagement issues and premature wear.

• Starter type: PMGR (Permanent Magnet Gear Reduction).
• Voltage: 12V; Power rating: 1.1 kW; Rotation: clockwise; Tooth count: 9.
• All-new unit—ensures consistent internal tolerances and performance.

Who this is for: Drivers, DIY mechanics, and professional technicians working on mid-2000s GM light trucks and vans with 4.8L or 5.3L V8 engines who need a reliable, ready-to-install replacement starter. Ideal when the original starter shows slow cranking, audible gear slip, or outright failure, and when an exact-spec, plug-and-play, all-new unit is preferred over a remanufactured core.
