Will it fit my 1998 Jeep Wrangler 4.0L?

Yes. It is listed for 1991–2004 Wranglers with the 4.0L inline-six. Confirm your engine before ordering, since it does not fit the 2.5L.

Is it stronger than a stock starter?

Powermaster positions it as a higher-torque replacement, which helps on modified or high-compression 4.0L engines. On a stock engine it behaves like a healthy factory starter.

Is it a direct bolt-in?

Yes. It is a direct-fit replacement for the original starter on the listed Wrangler applications, with no adapter needed.

Does it work with a winch and extra lights?

It is a starter, not a charging upgrade. Added electrical load is better addressed with a stronger battery and alternator; the starter only cranks the engine.

The starter unit itself. Reuse your existing mounting bolts and wiring unless the listing states otherwise.

Is it worth it over a rebuilt starter?

If you run a built 4.0L or want a stouter unit, the Powermaster is the more robust choice. For a stock daily driver, a quality rebuilt starter is a cheaper option.
