Irs Pivot Pockets, for Aftermarket VW Torsion, Pair Dunebuggy & VW For Sale

When you\'\'re building a high-performance off-road beast or converting a classic swing axle chassis to a modern Independent Rear Suspension (IRS) setup, the structural integrity of your pivot points is non-negotiable. These EMPI IRS Pivot Pockets are engineered specifically for aftermarket torsion housings, providing the rock-solid foundation needed to mount your trailing arms with precision. Unlike stock replacements that are designed for factory dimensions, these pockets feature the correct geometry and heavy-duty steel construction required to withstand the lateral forces and vertical travel common in dune buggies, woods buggies, and custom street builds. By utilizing these high-quality brackets, you ensure that your rear suspension geometry remains consistent, preventing unwanted toe or camber changes during aggressive driving maneuvers.

For the serious fabricator, these pivot pockets offer the perfect blend of ease of installation and long-term durability. Designed to be welded directly onto a custom 3-inch or aftermarket torsion tube, they provide a clean, professional finish that mimics factory IRS mounting points but with improved material thickness for heavy-duty applications. Whether you are upgrading a standard Beetle for better handling on the pavement or constructing a long-travel sand rail meant for the dunes, these pockets are the industry standard for securing your inner trailing arm bushings. The pair includes both left and right sides, ensuring a balanced and symmetrical rear-end setup. Don\'\'t settle for makeshift brackets when you can install components that are purpose-built to handle the torque and stress of a high-performance air-cooled VW drivetrain.

1. Precision Alignment is Paramount

Before you strike an arc, it is absolutely critical to ensure your pivot pockets are perfectly aligned. We recommend using a long, straight alignment bar or a dedicated IRS jig that passes through both pockets simultaneously. This ensures that your trailing arms will be perfectly square to the chassis, preventing \"dog-tracking\" and premature tire wear. Even a fraction of an inch of misalignment at the pivot point can lead to massive toe-in or toe-out issues that cannot be corrected later through standard alignment methods. Take the time to measure three times and tack-weld everything before performing the final bead.

2. Proper Surface Preparation for Strength

Since these pockets are critical suspension components, your weld penetration must be flawless. These pockets come in a raw steel finish, but they may have a thin layer of shipping oil or light surface oxidation. Use a flap disc or wire wheel to clean both the torsion tube and the contact edges of the pivot pockets until you have bright, shiny metal. After cleaning, use a solvent like brake cleaner or acetone to remove any remaining oils. This ensures a clean, slag-free weld that can handle the extreme leverage exerted by the trailing arms during hard cornering or off-road landings.

3. Protect Your Bushings and Bearings

Never install your trailing arm bushings or the arms themselves while welding the pivot pockets into place. The intense heat generated during the welding process will melt urethane bushings or damage the seals of specialty bearings. Weld the pockets, allow them to air-cool naturally (do not quench them with water as this can make the steel brittle), and then paint or powder coat the area to prevent rust. Only after the metal has returned to ambient temperature should you install your bushings and hardware. Additionally, remember to use high-quality Grade 8 hardware for the pivot bolts to match the strength of these heavy-duty pockets.
