Application and Buying Notes

When checking this starter motor, start with the part number DXS4051, then compare the mounting style, 12V rating, 9-tooth pinion, and clockwise rotation against the existing unit. The pad mount design, M10 mount hole diameter, 91mm mount centre to centre, and 74mm flange diameter are the main physical checks that help confirm whether the starter will line up correctly.

The listed Denso style and suits unit make of Denso are important because starter motors are often matched by the original unit type as much as by the vehicle badge. The 229mm overall length, 29mm pinion diameter, and 26mm pinion at rest give you further reference points if the old starter is available for comparison.

This starter motor is a new unit with a 2.0kW power rating and 4.2kg weight. Those figures are useful when comparing electrical capacity and physical size, but they should not replace an application check. If the old starter is missing, damaged, or unreadable, use the part number, mounting pattern, rotation, tooth count, and Denso application details together before ordering.

The supplied fitment data points to Lexus GS and Toyota Crown applications, with additional Lexus model families referenced in the broader fitment list. Even where a vehicle family appears in the fitment data, exact engine and build details still matter for starters, so confirm the match carefully rather than relying on make alone.

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 DXS4051 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.
