Product Description
Unlike broader starter listings, C4948058 is more closely tied to Cummins B Series engine replacement demand and the aftermarket channels serving diesel engine distributors, truck workshops, industrial repair buyers, and engine service companies. Buyers searching this reference are usually not looking for a generic Prestolite unit. They are more often trying to match a 24V 6kW 12-tooth heavy duty starter motor used on Cummins 4B, 4BT, 4BTA, 6B, 6BT, 6BTA, EQB, BGE, and ISBE engine platforms.
That difference matters. In this segment, the purchase decision is usually driven by OE number confirmation, Prestolite model confirmation, 24V voltage, 12-tooth pinion, clockwise rotation, and the M93 offset-mounting layout, rather than by appearance alone. Public references also support 10/12 DP pinion pitch, SAE1 mounting type, grounded-earth return, no OCP, and 89 mm spigot diameter, which are useful checkpoints for serious B2B buyers before quotation.
With 24V system voltage, 6kW output, 12 teeth, approx. 37mm pinion diameter, and 89mm engagement / spigot reference, this C4948058 heavy duty starter motor is especially suitable for buyers serving Cummins B Series engine service, industrial diesel engine replacement, and regional aftermarket stock programs. Compared with off-highway crawler or mining starter programs, this product is more naturally positioned for Cummins engine-driven equipment, bus, truck, and generator-related service channels.
For businesses building product lines for Cummins starter motor wholesale, Prestolite OEM replacement supply, or B Series engine aftermarket distribution, Elecdurauto can support bulk supply, fitment review, neutral packaging, and private label cooperation based on project requirements. The public application direction around 4BT, 6BT, and related B Series engines makes this product a practical B2B stocking item rather than a one-off retail reference.

Yes. C4948058 is the strongest lead OE for this starter group because public replacement references most consistently connect it to Prestolite M93R3001SE and to Cummins B Series engine demand.
The main difference is its stronger association with Cummins B Series diesel engine service rather than general starter interchange searching. Buyers usually search this reference when they need a more reliable match for 4BT, 6BT, and related B Series engine applications.
Yes. Public references repeatedly group C4948058, 4948058, and M93R3001SE together in the same replacement family. Final confirmation should still be based on the actual starter layout and engine application.
The most important points are OE number, 24V voltage, 12-tooth pinion, clockwise rotation, offset mounting, and the M93 installation structure. If the original starter is available, checking the spigot diameter, pinion size, and housing layout will further reduce mismatch risk.
Typical buyers include importers, Cummins engine parts distributors, repair parts wholesalers, diesel engine service suppliers, and regional aftermarket buyers serving B Series engine replacement demand. This is more of an engine-service and parts-program product than a retail one-off starter.
Yes. As an export-oriented replacement unit for Cummins B Series engines, it can fit aftermarket demand in regions where 4BT, 6BT, industrial diesel engines, buses, trucks, and generator-related applications are already in service. The safest approach is still to confirm the OE number and old-unit details before bulk orders.
Yes. Neutral packaging, custom labels, and private label packaging can be arranged according to order quantity, branding requirements, and destination market needs.
The standard MOQ is 50 pcs. For repeated supply projects, annual stocking plans, or distributor orders, production and delivery schedules can be discussed based on business needs.
Because the clearest application and reference signals are centered on Cummins OE numbers and Cummins B Series engine demand, even though the starter itself belongs to the Prestolite M93 family. For navigation and SEO, Cummins Starter Motor is the strongest primary classification.
The most useful information includes the Cummins OE number, Prestolite reference, engine model, starter photos, required quantity, and any available nameplate or dimensional data. For this starter group, references such as 4B, 4BT, 4BTA, 6B, 6BT, 6BTA, EQB, BGE, ISBE, or 6CT are especially helpful during confirmation.
