Underdrive pulley 5.5" serpentine TC pump.
The PP2402 is a 5.5" diameter billet aluminum overdrive pulley designed to increase pump speed at lower engine RPM. It's a press-fit, 6-rib serpentine pulley that fits PSC Type II, TC, CBR, and CBX power steering pumps with a 5/8" driveshaft.
This pulley is a solid choice for applications that need better steering assist at idle and low RPM, especially late-model Jeep 3.6L Pentastar setups and Jeep builds using GM LS engine conversions. The larger diameter helps keep steering feel consistent without putting extra strain on the system.
