Irs Spring Plates, Adjustable, for 26-9/16 Inch Torsion

OVERVIEW

Upgrading your air-cooled Volkswagen''s rear suspension no longer requires the grueling, time-consuming process of indexing and re-indexing torsion bar splines just to achieve the perfect ride height. These Latest Rage Adjustable IRS Spring Plates are engineered specifically for the 26-9/16 inch torsion bar setup, providing a massive performance boost for owners of 1968 to 1971 Type 1 and 1967 to 1971 Type 3 models. Designed to replace the cumbersome factory double spring plate configuration, these high-strength units allow you to fine-tune your suspension height with a simple turn of a bolt. Whether you are looking to level out a sagging rear end, compensate for varying passenger loads, or dial in the perfect stance for the drag strip or the street, these plates offer the precision and durability that Appletree Auto customers demand.

Beyond simple convenience, these adjustable spring plates are built to handle the rigors of both daily driving and spirited off-road use in dune buggies and sand rails. Constructed from heavy-duty steel and finished to resist the elements, they provide a stable foundation for your Independent Rear Suspension (IRS). By switching from the original fixed plates to these adjustable versions, you gain the ability to compensate for torsion bar fatigue over time without having to tear down the entire rear end of the vehicle. This kit is sold as a pair and is the ultimate solution for any VW enthusiast who wants to combine classic engineering with modern adjustability and ease of maintenance.

PRO TIPS

1. Confirming Your Torsion Bar Length

One of the most common mistakes in VW suspension restoration is ordering the wrong length spring plate. Before purchasing, inspect your torsion housing end caps. If the cap is solid and flat, you likely have the shorter 21-3/4 inch bars. However, if the cap has a hole in the center with a torsion bar stub protruding through it, you are in the right place for these 26-9/16 inch plates. Always measure from the tip of the spline to the tip of the spline to ensure a perfect fit, as many buggies and kit cars use mismatched housings and bars from different years.

2. Proper Bushing Selection and Lubrication

When installing these adjustable plates, you must use the specific bushing sizes: a 2-inch I.D. for the inner and a 1-7/8 inch I.D. for the outer. We highly recommend using high-quality urethane bushings for increased responsiveness. To prevent the notorious ''''VW squeak,'''' apply a generous amount of specialized silicone-based grease or anti-seize to the inner and outer surfaces of the bushings. This ensures the spring plate can pivot smoothly through its travel without binding or making noise, which is especially important once you start utilizing the adjustment bolt.

3. Setting the Baseline Adjustment

When you first install these plates, it is best practice to set the adjustment bolt to the middle of its travel range. Index your torsion bars so that the vehicle sits close to your desired height at this middle setting. This gives you the maximum ''''up'''' or ''''down'''' adjustment range later on. Once the car is back on the ground and the suspension has settled (after a short drive), you can then use the adjustment bolts to perfectly level the car from side to side, compensating for driver weight or slight variations in torsion bar tension.
