Product Description
The CARDONE 20-5001R Remanufactured Power Steering Pump is precision-engineered to restore smooth steering control and dependable hydraulic performance for 2011–2015 GM heavy-duty trucks. Designed to meet or exceed OEM specifications, it ensures quiet operation, proper flow, and lasting durability under the most demanding load conditions.
Each unit undergoes comprehensive hydraulic testing, validating pressure, flow rate, and bypass operation for optimal performance. CARDONE’s triple-testing process for spool valves, cam packs, and shafts ensures exceptional reliability, while premium-grade HNBR seals resist high temperatures and fluid breakdown. The pump’s precision-ground shafts prevent premature seal wear, delivering extended service life and consistent steering assist.
In addition, CARDONE’s remanufacturing process is eco-conscious, reducing raw material and energy use by up to 80% compared to new production, making it both a performance and sustainability choice.
