Shock Boss, 1/2 Threaded Hole, 2 Long, Each

Overview

When you are pushing the limits of your air-cooled Volkswagen off-road, the factory shock mounting points often become the weakest link in your suspension geometry. The EMPI Shock Boss is the definitive solution for fabricators and enthusiasts looking to build a bulletproof suspension system from the ground up. Engineered for extreme duty, this 2-inch long weld-on boss provides a rock-solid anchoring point for your dampers, ensuring that your shocks can handle the violent cycles of a high-travel Baja Bug, sand rail, or custom tube-chassis buggy. By utilizing a high-grade steel construction, these bosses allow for deep weld penetration into your chassis or control arms, creating a structural bond that resists the shearing forces and constant vibration inherent in off-road racing and aggressive trail riding. Whether you are relocating your shocks for better articulation or reinforcing a vintage Manx-style build, these bosses offer the professional-grade foundation required for a high-performance setup.

The versatility of the 1/2-inch American tapped thread makes this Shock Boss a staple in the fabrication shop. Unlike metric alternatives that can be difficult to source hardware for in a pinch, the 1/2-inch threading is compatible with a wide array of high-tensile Grade 8 bolts, commonly used in racing applications for their superior yield strength. The 2-inch length provides ample clearance for shock eyes and spacers, allowing you to fine-tune your shock alignment to prevent binding during full compression or extension. At Appletree Automotive, we understand that precision is everything in a custom build; that is why we provide these bosses as individual units, giving you the flexibility to order exactly what you need for a dual-shock setup or a simple repair. Don''t settle for flimsy, stamped brackets when you can install a heavy-duty boss that is designed to survive the harshest environments the desert can throw at you.

Fitment

This is a universal fabrication component designed for custom weld-on applications. While it is commonly used on the following Volkswagen-based vehicles, it can be adapted to any tube or plate steel surface:

• Volkswagen Baja Bug: Custom rear torsion housings and front beam supports.
• Sand Rails & Dune Buggies: Ideal for custom frame rails and shock towers.
• Manx & Fiberglass Buggies: Strengthening shock mounts on shortened pans.
• Type 1 Beetle: Custom drag racing or off-road suspension conversions.
• Type 2 Bus: Heavy-duty shock relocations for lifted or lowered stances.
• Type 3 Squareback/Fastback: Custom rear suspension fabrication.
• Karmann Ghia: Performance suspension upgrades requiring relocated mounting points.

Pro Tips from the Appletree Garage

1. Proper Surface Preparation for Structural Integrity

Before you even think about striking an arc, ensure that the mounting surface on your chassis or control arm is ground down to shiny, bare metal. Since these shock bosses are made of mild steel, they weld beautifully, but any paint, powder coating, or rust will contaminate the weld pool and lead to a brittle joint. Use a flap disc to clean the area, and consider chamfering the base of the boss slightly to allow for deeper weld penetration. A deep, consistent bead around the entire circumference of the boss is essential to ensure it doesn''t tear away under the high leverage of a long-travel shock.

2. Protecting the Threads During the Weld Process

One of the most common mistakes builders make is warping the internal threads due to excessive heat or getting weld spatter inside the hole. To prevent this, thread a sacrificial 1/2-inch bolt (not your final high-grade hardware) into the boss before you start welding. This acts as a heat sink and keeps the internal threads clean. Once the weld has cooled naturallynever quench it with water, as this can make the steel brittleremove the sacrificial bolt and run a 1/2-inch tap through the boss to "chase" the threads and ensure perfectly smooth hardware installation.

3. Geometry and Mock-Up is Key

Always mock up your suspension through its entire range of motion (from full bump to full droop) before final welding of the Shock Boss. Use a floor jack to cycle the suspension and ensure that the shock eyelet does not bind against the boss or the chassis at any point. Because these are 2 inches long, you have the "meat" to trim them down slightly if your specific offset requires it, but it is always better to have the extra length for spacing. Ensure the boss is perpendicular to the shock''s travel arc to prevent premature wear on your shock bushings or rod ends.
