This 4.5" diameter billet aluminum overdrive pulley is engineered to spin your power steering pump faster at lower engine speeds. By increasing pump speed at idle and crawl RPM, this pulley improves steering assist and response without compromising belt alignment.

Machined with the correct Mopar Jeep offset, this press-fit 6-rib serpentine pulley is designed for Type II, TC, CBR, and CBX power steering pumps using a 5/8" shaft. Its a simple, proven upgrade for trail rigs, rock crawlers, and older Jeeps that demand better low speed steering performance.

Tech Insight

Low engine RPM is where most trail rigs struggle with steering feelespecially heavy front axle builds running big tires and hydro assist. By slightly overdriving the pump, this 4.5 pulley increases flow at idle without changing pump internals or affecting high-RPM reliability.

For rock crawlers and off-road Jeeps, this is one of the easiest ways to gain better steering response during slow-speed maneuvering and technical obstacles.
