The DieselSite PSPKOBS is an overdrive pulley kit for the power steering pump on 1994-1997 Ford 7.3L OBS Powerstroke trucks. It spins the pump faster for about 10 percent more fluid volume.

More volume helps power assist at low speed, especially with large tires or a hydroboost brake system. The kit includes the belt needed for the change in pulley size.

• Overdrive Pulley: Spins the pump faster than stock.
• About 10% More Flow: Extra fluid volume for assist.
• Belt Included: Correct length for the new pulley.
• Bolt-On Install: Replaces the factory pump pulley.
• OBS Specific: Made for the 7.3L OBS pump.
