This Denso starter motor is a new 12V unit with a 1.6kW power rating and clockwise rotation. It is listed as an OE product and carries part number 428080-1240, which is the most reliable reference when checking a replacement starter against the vehicle application.

The unit is a 2-hole starter mount type with 113mm mount centres, a 74mm flange diameter, and M10x1.25 mount hole diameter. Overall length is 182mm, with a 31mm pinion diameter and 21mm pinion at rest, so the physical dimensions are important to confirm before ordering.

Application and Buying Notes

When replacing a starter motor, match the part number 428080-1240 first, then check the mounting details against the original unit. The key dimensions here are 113mm mount centres, 74mm flange diameter, M10x1.25 mount holes, 182mm overall length, and a 2-hole mounting pattern.

The electrical and drive details also need to line up with the vehicle’s original starter. This unit is 12V, 1.6kW, clockwise rotation, with 10 teeth and a 31mm pinion diameter. It is listed for dry clutch use, so that detail should be checked carefully before purchase.

If the old starter is still available, compare the pinion at rest measurement of 21mm and the unit weight of 2.78kg as additional checks. Those figures are often helpful when confirming whether the replacement is physically the same style as the one being removed.

Fitment information is provided for Lexus GS, Lexus IS, Lexus IS C, Lexus RC, Toyota Hilux, and Toyota Land Cruiser Prado applications. Even where a vehicle model appears in the fitment list, final confirmation should still be made against the part number, mounting style, and dimensions on the vehicle.

This starter is sold as a new OE product from Denso and is covered by a one-year warranty. That gives a straightforward replacement option where the original starter has failed, but the correct application still depends on matching the vehicle details and the starter configuration exactly.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number 428080-1240 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.
