Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components. 

Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved acceleration response, more direct shifting feel and overall improved drivetrain composure with Powerflex performance polyurethane bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle.

Introducing the Air Lift Performance 3S Air Management Kit

The Air Lift Performance 3S is a groundbreaking air management kit that takes performance to the next level. This kit includes a manifold and a basic wiring harness, providing the flexibility to be installed in conjunction with separately purchased components. It is compatible with both 1/4” and 3/8” air lines, offering various kit versions to cater to different displays and switch boxes or exclusive use with the ALP3 app. Whichever version you choose, seamless integration with the ALP3 app is guaranteed.

Components to be purchased separately include:

• Air springs
• Water trap
• Controllers (e.g., AVS switchbox)
• Fittings/air lines
• Compressor
• Insulated copper wires in 10-, 12-, 18-, and 20-gauge
• Tank wire, connectors, terminals, butt splices
• Pressure switch fuse/holders
• Relay
• Schrader valve and blow-off valve

Additionally, there are versions of the 3S kit available with the Air Lift Performance V2 or ALP3 controller or just the smartphone app for added convenience.

When dismantling a suspension strut sometimes the securing nut can be difficult to access and the central strut itself needs to be held still while the nut is undone. This new Shock Absorber Tool Kit is designed to overcome these problems and make the job quick and easy.

The go-through design of the sockets and ratchet design allows the strut lock extensions to go right through the middle of the ratchet and socket. Five different strut lock extensions are included, to fit a variety of applications. Seven go-through deep sockets (16, 17, 18, 19, 21, 22 and 24mm) are included, plus a sliding T-bar.

Once the spring is compressed and the top plate is free, simply choose the correct strut lock extension and socket. Then fit the socket and the ratchet handle, and fit the strut lock straight through. The central strut is held steady, and the securing nut is quickly removed.

Specifically designed for repairing and replacing shock absorbers and struts

Schwaben Shock Nut Socket - 16mm

The Schwaben Shock Nut Socket - 16mm is an essential tool for securely mounting shocks to their mounts. Designed to help achieve the correct torque specification, this socket allows the use of an internal hex wrench to hold the damper shaft in place while using a torque wrench to apply the correct torque. Properly torquing the retaining nut is crucial to prevent premature mount failure or loosening. This high-quality socket ensures a precise fit and reliable performance for maintaining your vehicle's suspension system.

Benefits:

• Allows accurate torquing of shock retaining nuts to prevent mount failure
• Designed for use with an internal hex wrench to secure the damper shaft
• Ensures proper torque application with your torque wrench
• Helps avoid premature mount failure and nut loosening
• High-quality construction for durable and reliable performance
• Compatible with 16mm shock nuts
