Knobby Spring Plate Grommets, 1-7/8 ID, Bugpack, Pair

OVERVIEW

Upgrade your air-cooled Volkswagen''s rear suspension with the BUGPACK Knobby Spring Plate Grommets, specifically engineered to eliminate the sloppy handling and annoying squeaks associated with aged, factory rubber bushings. Unlike standard OEM rubber components that tend to compress, dry rot, and eventually "bottom out" under the stresses of daily driving or off-road excursions, these high-performance urethane grommets feature a unique "knobby" or ribbed design. This specialized texture provides superior resistance to compression while allowing for better lubrication retention, ensuring that your spring plates remain perfectly centered within the housing. When you are looking to restore the original ride quality of your Beetle or enhance the stability of your weekend cruiser, these BUGPACK grommets offer the durability and precision that Appletree Auto customers have relied on for decades.

The 1-7/8 inch inner diameter is a critical dimension for specific year ranges and positions on the Type 1 and Type 3 chassis. By switching to a high-durometer urethane material, you are effectively tightening the rear suspension geometry, which leads to more predictable cornering and reduced wheel hop during acceleration. These grommets act as the pivot point for your rear torsion system; if they are worn, your entire rear alignment suffers. Sold as a pair, these BUGPACK grommets are an essential component for any comprehensive rear end rebuild, providing a "set it and forget it" solution that outperforms stock rubber in every measurable category. Whether you are running a stock height street car or a lifted woods buggy, maintaining the integrity of your spring plate centering is paramount for safety and performance.

PRO TIPS

1. Use Only Silicone-Based Lubricants

When installing these urethane grommets, it is absolutely vital to use a high-quality silicone-based grease or the specialized "sticky" grease often provided with urethane kits. Never use petroleum-based grease, as it can actually break down the urethane material over time and lead to premature failure. Applying a generous coat of silicone grease to both the inner and outer surfaces of the grommet will prevent the dreaded "urethane squeak" that occurs when the material rubs against the metal spring plate or the torsion housing. A properly lubricated set of grommets will remain silent for years of operation.

2. Thoroughly Clean the Torsion Housing and Spring Plate

Before sliding the new BUGPACK grommets into place, take the time to use a wire brush or a flap disc to remove all rust, old rubber residue, and road grime from the spring plate tube and the inside of the torsion housing cover. Even a small amount of debris can cause the new grommet to sit unevenly, which leads to binding or uneven wear. Once the metal surfaces are clean and smooth, wipe them down with a solvent like brake cleaner to ensure no oily residue remains before applying your new silicone lubricant and seating the grommets.

3. Check for Torsion Bar Spline Wear

While you have the spring plates removed to replace these grommets, it is the perfect opportunity to inspect the splines on your torsion bars. Look for any signs of twisting or heavy rust that could compromise the strength of the bar. If the splines are covered in surface rust, clean them carefully and apply a light coat of anti-seize or heavy-duty grease to the splines before reassembly. This prevents the torsion bars from seizing inside the spring plates, making future ride-height adjustments or maintenance significantly easier. Doing the job right the first time means checking the components that interact with your new grommets.
