Powermaster 9416 Ultra Torque Starter, 2.5 kW, Jeep 4.0L

This is Powermaster's 9416 Ultra Torque starter, a gear-reduction unit sized for the 4.0L engine in late-model Jeep applications, finished in the mini, gold-iridited housing named in the listing. The billet aluminum mounting block rotates to four positions and is adjustable, so the starter can be indexed for clearance against headers, oil pans or steering components before final bolt-up.

What it's rated for

Powermaster publishes a 2.5 kW rating and 3.4 HP of output for this starter, with a 4.4:1 gear reduction. The Ultra Torque line is rated at 250 ft-lbs of cranking torque, enough for engines running compression as high as 18:1, which covers a mildly to moderately built 4.0L without stepping up to a heavier-duty unit. Rotation is clockwise.

Before you order

Powermaster does not publish specific model years for this application. Confirm the fit against your Jeep's exact year and engine combination before ordering, since mounting and flywheel tooth count can change across model years even within the same 4.0L family. The starter is manufactured in the USA.

Common questions

Will the mounting block clear my headers? It indexes to four rotational positions, giving room to work around tight header or chassis clearance.

Is this a direct swap for a stock starter? It's a gear-reduction design rather than a direct-drive unit, so expect a more compact size and higher cranking torque than a factory starter.
