Bump Stop, Stacked Round with Molded Stud, Pair

OVERVIEW

Protecting your air-cooled investment starts with a suspension that can handle the unexpected, and these EMPI Stacked Round Bump Stops are the front line of defense for your shocks and chassis. When you''re pushing your Volkswagen Beetle through a tight corner or navigating a rugged trail in a custom woods buggy, the last thing you want is for your suspension to bottom out against the internal valving of your shocks. These high-performance red urethane bump stops act as a progressive cushion, absorbing the energy of a full compression stroke before it can cause permanent damage to your shock pistons, seals, or mounting points. At Appletree Auto, we know that a broken shock mount can end a weekend of fun instantly; installing these rugged urethane stops is one of the most cost-effective ways to ensure your ride stays smooth and your hardware remains intact.

Crafted from premium-grade red urethane, these stacked round bump stops are designed for maximum durability and a universal fit that makes them a favorite for custom builders and restorers alike. The unique "stacked" geometry allows for a more controlled compression rate compared to standard flat stops, providing a smoother transition as the suspension reaches its limit. Each stop features a heavy-duty 3/8-inch stud molded directly into the base, ensuring it won''t tear away under heavy load or vibration. This design allows for a clean, secure installation on any flat surface, mounting tab, or tapped hole on your beam or trailing arms. Whether you''re finishing a show-quality Ghia or building a high-flying Baja, these EMPI bump stops provide the "insurance" your suspension system deserves.

PRO TIPS

Pro Tip 1: Measure Your Shock Travel Before Installation. To get the most protection, you must ensure the bump stop makes contact before your shock reaches its absolute bottom-out point. Pull the spring or torsion bar tension if possible, and cycle the suspension. The bump stop should be positioned so that it compresses fully just before the shock piston hits the bottom of the shock body. This prevents the shock from acting as the "stop," which is the leading cause of internal seal failure and bent shock shafts in off-road VWs.

Pro Tip 2: Use a Reinforcement Plate for Thin Tabs. If you are mounting these bump stops to a custom-welded tab on a sand rail or Baja, ensure the tab is at least 3/16-inch thick. If your mounting surface is thinner, the force of a hard bottom-out can bend the tab or pull the stud through the metal. Adding a simple 2-inch diameter "fender washer" or a secondary reinforcement plate on the back side of the mount will distribute the impact force across a larger surface area, preventing fatigue in the metal over time.

Pro Tip 3: Keep the Stud Clean and Don''t Overtighten. While urethane is incredibly tough, the molded-in stud relies on the integrity of the material around it. When installing, use the provided nylon lock nuts and tighten until the base of the bump stop is flush and firm against the mounting surface. Do not use an impact wrench to "crush" the base into place, as this can stress the bond between the steel stud and the urethane. A drop of blue thread locker on the stud, in addition to the nylock nut, provides extra peace of mind for high-vibration off-road environments.
