KYB MonoMax Rear Shock for Ram 2500

• Off-road dust boot helps protect the shaft and seal area from dirt and debris
• Engineered to support vehicles with electronic safety systems such as ESC and ABS

• Lower mount type: E2 (14.6 x 42); upper mount type: S1 (12 mm)

Product Details

KYB MonoMax is the truck-focused product line from KYB, built for applications that need firmer control and consistent damping under load. The 5650010 rear shock uses a monotube layout to improve heat management and maintain fade-resistant performance during towing, hauling, and off-road use. For Ram 2500 owners, this rear shock is a direct-fit option for trucks without rear air spring and without heavy duty shocks. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Shock Can Address

• Excessive rear-end bounce after bumps or dips
• Reduced stability when towing a trailer
• Rear suspension sag or poor control under load
• Harsh, inconsistent damping from worn factory shocks
• Dust and debris exposure around the shock shaft and seals
