Product Description
Upgrade the weak factory steering on your 3rd Gen Ram with the PSC SK853 BIG BORE XD Cylinder Assist Steering Kit. Engineered specifically for 2003-2008 Dodge Ram 2500 and 3500 4WD trucks, this complete hydraulic assist system dramatically improves steering control when running oversized tires, heavy front axle loads, or extreme off-road conditions. PSC’s BIG BORE XD® technology distributes steering load between the steering gear and hydraulic assist cylinder, reducing stress on factory steering components while improving steering response and durability. The result is more precise steering control, improved steering dampening, and better overall reliability when pushing your Cummins truck in demanding environments. Designed for serious diesel performance builds, off-road trucks, rock crawlers, and heavy-duty work rigs, the PSC SK853 system provides the additional hydraulic force required to steer larger tires and upgraded axles without excessive strain on your steering box or pump. This kit includes PSC’s BIG BORE assist cylinder, modified steering gear, hoses, and mounting hardware required to complete the installation.

Frequently Asked Questions
What does a cylinder assist steering system do?
A hydraulic assist steering system adds a steering cylinder that works with the steering gear to help turn the front wheels. This reduces steering effort and improves control when running large tires or heavy axle loads.
Is the PSC SK853 kit designed specifically for 3rd Gen Ram trucks?
Yes. The SK853 kit is engineered specifically for 2003-2008 Dodge Ram 2500 and 3500 4WD trucks and integrates with PSC steering components designed for this platform.
Do I need hydraulic steering assist for larger tires?
If you run oversized tires, locking differentials, or upgraded axles, hydraulic assist steering dramatically reduces steering stress and improves steering response under heavy load.
Will this fix steering wander?
Hydraulic assist improves steering control but will not correct worn suspension or steering components. Ensure your steering linkage, track bar, and ball joints are in good condition before installation.
Is this system compatible with steering box braces?
Many aftermarket steering box braces are not compatible with PSC cylinder assist systems. Verify clearance and compatibility before installation.
