OLIFANT Starter Motor for Arctic Cat 250/300 & Suzuki King Quad 300 — 12V CCW 10-Tooth, Includes Relay

OLIFANT replacement starter with relay for Arctic Cat 250/300 and Suzuki King Quad 300 — 12V PMDD, 10-tooth CCW drive designed to restore reliable cranking across compatible ATVs.

This OLIFANT starter unit is a direct-fit replacement built for a range of late-1980s through mid-2000s Arctic Cat and Suzuki four-wheelers. It pairs a precision permanent-magnet DC (PMDD) motor with reduction gearing to deliver steady cranking torque while minimizing battery draw. The assembly ships with the starter motor and a relay so you have the essential parts to replace a worn or failed starter without sourcing multiple components.

Which ATV models and years will this starter fit?

This starter is engineered to match bolt patterns, spline counts, and electrical requirements for several Arctic Cat and Suzuki models spanning model years. It fits Arctic Cat 300 (1998–2005), Arctic Cat 250 (1999–2005), and Suzuki King Quad 300 (1991–2002), plus related Quadrunner/LT models as listed by part numbers.

• Arctic Cat 300: 1998–2005
• Arctic Cat 250: 1999–2005
• Suzuki King Quad/Quadrunner 300 series: 1991–2002
• Cross-reference part numbers: 3545-003, 3545-017, 31100-19B00, 31100-19B11, 31100-19B12, 31100-19B20

How is this starter constructed and why does it matter?

The motor uses a PMDD configuration and compact reduction gears to produce consistent cranking speed and torque while keeping electrical demand low. Higher-quality internal components extend service life and reduce the risk of weak starts caused by worn brushes or gear slippage.

• Permanent-magnet DC motor for efficient power delivery
• Reduction gearing for increased torque at the flywheel
• 12V, counter-clockwise (CCW) rotation with 10-tooth sprocket/spline
• Built to reduce current draw, helping preserve battery life

What’s included and what should I check during installation?

The package contains one starter motor plus one starter relay so you have the primary components needed for replacement. During installation, verify electrical connections, mounting bolt pattern, and spline engagement to ensure correct fit and reliable operation.

• Contents: 1 x starter motor, 1 x relay
• Confirm CCW rotation and 10-tooth spline compatibility with your model
• Inspect battery health and wiring for clean, tight connections
• Torque mounting bolts to manufacturer specs and test cranking

Will this starter improve starting performance on older ATVs?

Replacing a worn starter with this OLIFANT unit restores consistent cranking speed and reduces electrical stress on the battery, often leading to quicker, more reliable starts. It won’t change engine tune or fuel delivery, but it addresses mechanical or electrical failure points in the starting system.

• Restores dependable cranking for worn starter systems
• Reduces excessive current draw that can weaken batteries
• Improves engagement reliability thanks to quality reduction gears

Who is this for: Riders, mechanics, and restoration enthusiasts working on Arctic Cat 250/300 and Suzuki King Quad/Quadrunner 250–300 models who need a durable, direct-replacement starter and relay. Choose this unit if you require correct spline count, CCW rotation, and a solution that minimizes battery strain while delivering steady cranking power for older ATVs.
