Description
The Koni Bump Stop is the essential hardware upgrade for 2008-2009 Pontiac G8 owners running Koni Sport (Yellow) adjustable struts.
Unlike universal rubber alternatives, these cellular polyurethane bump rubbers act as a secondary progressive spring, increasing resistance as they compress to provide a controlled “bottoming” effect without the harsh metal-to-metal contact that damages internal shock valving.
Why G8 Owners Choose Koni Bump Stops? Precision Fitment! Engineered specifically for 16mm to 20mm rod diameters, ensuring a snug fit on Koni Sport strut inserts.
Progressive Damping: The 1.570-inch conical shape provides a “soft-touch” initial engagement that firms up rapidly, maintaining ride quality even on lowered G8s.Enhanced Durability: High-grade black polyurethane resists oil, road salt, and heat better than standard foam or rubber stops.
Suspension Protection: Prevents expensive “over-travel” damage to your Koni Yellows during heavy impacts or performance driving.
