Tapered Spacers Aluminum 1/2in ID x 1in Long ALL18596

High-Performance Aluminum Tapered Spacers for Precision Fabrication

When it comes to dialing in the suspension geometry on your air-cooled VW or custom off-road rail, the devil is always in the details. These Allstar Performance Tapered Aluminum Spacers are engineered to solve one of the most common headaches in custom fabrication: suspension binding. Whether you''re mounting high-travel shocks or setting up radius rods on a rugged Baja Bug, these spacers provide the necessary offset to allow your rod ends to rotate freely throughout their entire range of motion. By utilizing a tapered profile, these spacers ensure that the housing of your Heim joint doesn''t make premature contact with the mounting bracket, which is a critical factor in preventing bent bolts or snapped rod ends during aggressive off-road maneuvers or high-speed desert crossings.

Crafted from premium-grade aluminum, these spacers offer a perfect balance of lightweight performance and structural integrity. At one inch in length with a precise 1/2-inch inside diameter, they are the go-to choice for builders who demand a clean, professional finish that off-the-shelf hardware store washers simply cannot provide. These aren''t just functional components; they are a statement of quality in your build. When you''re flying through the whoops or launching off a dune, you need to know that every component in your steering or suspension linkage is optimized for maximum articulation. These spacers deliver that peace of mind, ensuring your VW-based machine stays on the trail and out of the pits by providing a smooth, non-binding interface for all your critical pivot points.

Vehicle and Application Fitment

These tapered spacers are universal fabrication components designed for 1/2-inch hardware. They are commonly utilized in the following air-cooled VW and off-road applications:

• VW Baja Bugs: Ideal for rear shock mounting points and front beam support rods.
• Sand Rails & Dune Buggies: Perfect for radius rod ends and custom shift linkage setups.
• Meyers Manx & Kit Cars: Used in steering column support and custom pedal assembly spacing.
• VW Drag Racers: Essential for wheelie bar mounting and parachute release linkages.
• Type 1, 2, & 3 Custom Chassis: Any application requiring a 1/2-inch ID spacer to clear Heim joints or spherical bearings.
• Off-Road Racing: Fits most Class 5, Class 11, and Class 1/2-1600 suspension components using 1/2-inch grade 8 bolts.

Pro Tips from the Appletree Archive

Check for Maximum Articulation

When installing these spacers on a new suspension build, always cycle your suspension through its full range of travel (from full droop to full compression) without the springs installed. This allows you to visually verify that the Heim joint or rod end is not "bottoming out" against the taper of the spacer. While these are designed to prevent binding, extreme-angle suspension setups may require a specific orientation or additional clearance. Ensuring that the spacer provides enough "gap" at the maximum angle of the rod end will prevent the bolt from being subjected to prying forces that could lead to catastrophic failure on the trail.

Prevent Galvanic Corrosion

Since these spacers are made of aluminum and are typically used with high-strength Grade 8 steel bolts, there is a risk of galvanic corrosion, especially in humid environments or if you drive your VW near the ocean. To prevent the spacer from "seizing" to the bolt over time, always apply a thin layer of high-quality anti-seize lubricant to the shank of the bolt before sliding it through the spacer. This small step makes future maintenance and suspension tuning significantly easier, as you won''t have to fight a frozen spacer when it comes time to swap out your rod ends.

Use in Double Shear Configurations

For the ultimate in strength and safety, Appletree recommends using these tapered spacers in a "double shear" mounting configuration whenever possible. This means the bolt passes through a bracket on both sides of the rod end and spacer assembly. When you use a 1-inch long spacer, you are creating a significant lever arm; by placing this assembly between two plates of a bracket, you distribute the load evenly and prevent the bolt from bending. This is particularly important for shock mounts on heavy Baja Bugs or the steering links on high-horsepower sand rails where the steering forces can be immense.
