Bushing, Porsche 2" ID, Round Inside, 1968 & Up
Chassis Application: Engineered specifically for 1968 and newer (1968-Up) Porsche rear suspension architectures utilizing adjustable spring plate designs.
Inner Diameter (ID): 2” (Precision sized to slip over the inner sleeve or torque tube pivot cleanly with zero binding).
Inner Geometry: Round inside configuration engineered to seat tightly within the spring plate housing collar, eliminating radial walk or slop.
Material: Advanced High-Durability Elastomer Compound. Formulated from a high-grade elastomer that offers superior resistance to compression set, ozone degradation, road salts, and undercar petroleum exposure compared to standard OEM rubber.
Manufacturing Process: Precision-Molded. Produced using high-pressure injection molding to guarantee absolute dimensional uniformity and a completely flawless, void-free internal structure.
Performance Profile: Delivers optimal durometer stiffness to firmly support rear suspension load transitions without introducing the punishing harshness or loud metallic squeaking typical of track-only solid metallic bushings.
🧼 Thorough Housing Preparation: Before attempting to install the new 9205-2 bushing, the interior of the spring plate receiver cup and the mating surfaces of the inner sleeve must be completely immaculate. Use a wire wheel or abrasive pad along with brake cleaner to strip away any baked-on old rubber residue, rust, or scale. Any leftover grit or imperfections inside the housing will create friction hot spots, which will chew through the new elastomer material and cause rapid, premature failure.
🧴 Use Correct Assembly Lubrication: To prevent annoying suspension squeaks and bind-induced friction, apply a liberal coating of a high-pressure, water-insoluble silicone or synthetic grease (such as marine grade or specialized polyurethane lube) to the inner diameter and outer contact faces of the bushing. Never use a standard petroleum-based chassis grease or WD-40; petroleum-based lubricants will attack and chemically break down the elastomer material, causing it to soften, swell, and disintegrate within a few months.
📐 Aligning the Angular Spring Plate Indexing: When reassembling your Porsche's rear suspension, remember that the adjustable spring plate must be properly indexed on the torsion bar splines before the suspension is loaded. Take note of your original angle measurements or use a digital protractor to set the plate to the factory-specified hanging angle at full droop. Because this bushing services adjustable plates, ensure your fine-tuning eccentric bolts are centered during initial assembly to give yourself maximum adjustment sweep during final alignment.
🔩 Torque Hardware ONLY at Ride Height: Never torque down the main spring plate-to-trailing arm bolts or pivot mounts while the vehicle is hanging in the air on a lift or jack stands. Tightening the suspension fasteners while the suspension is at full droop locks the bushing into a twisted, pre-loaded state once the vehicle is lowered. This continuous rotational stress will instantly tear the elastomer structure during your first test drive. Always lower the car onto its wheels, settle the suspension by rocking the chassis, and then torque all hardware to factory specifications.
- ⏱️ Mandate a Professional Four-Wheel Alignment: Rear spring plate removal completely disrupts your Porsche's rear toe and camber settings. Because vintage Porsche rear suspension layouts feature highly sensitive kinematic interactions (where rear toe changes dynamically under load), a professional four-wheel laser alignment is absolutely mandatory immediately following installation to avoid dangerous snap-oversteer characteristics and accelerated tire wear.
