King 2.5 PR Series Bypass Shocks have become the industry standard for off-road racing bypass shocks. Not only are they built to take extreme abuse, they are the perfect size to tame your prerunner, rock crawler, or Ultra4 racer. Adjustable bypass tubes on the outside of the shock allow for zone-specific compression and rebound tuned for the ultimate in suspension control.

Shock Tuning Options
As soon as you place your order, one of our experienced shock tuning experts will review your shock specifications and contact you to finalize the details of your order. All King shocks are available with standard or custom tuning. For custom tuning, one of our shock tuning experts will work with you one-on-one to ensure your shocks are built perfectly for your application to provide the best balance of performance and ride quality. We will also help you determine the proper bypass tube layout and configuration for your vehicle. Standard valving is also available for do-it-yourself clients or those that plan to re-valve the shocks themselves with one of our King valve stack kits. Our standard valving is calculated to work well for most typical applications that would utilize this size shock.

5 of 5 2.5 x 8" 3 Tube King Bypass February 8, 2024
Reviewer: Kenneth from Las Vegas, NV  
Team, I just wanted to tell you guys the bypasses are a perfect fit. No tab adjustments needed and even the settings are in the ballpark. Ran all weekend without even an adjustment. Could not be happier and thanks for everything.
