How do I adjust the KONI Special D shock absorber?

The KONI Special D shocks are internally rebound adjustable. Adjustment is typically done by rotating the adjustment knob located at the bottom of the shock absorber. Refer to the manufacturer's instructions for the specific procedure for your vehicle.

What is the benefit of a twin-tube, low-pressure gas shock?

Twin-tube shocks generally offer good performance and are less sensitive to mounting orientation. The low-pressure gas charge helps to prevent foaming and aeration of the oil, which can lead to more consistent damping performance, especially under demanding conditions.

Does this shock absorber come with any mounting hardware?

This product listing is for the KONI Special D shock absorber itself. It is recommended to check the product details or contact customer support to confirm if any specific mounting hardware is included, as it often reuses original equipment or requires separate purchase.

Product Details

KONI has been known for making well-built suspension components for a long time, and their Special D (Red) shocks are a popular choice for drivers looking for improved handling. This particular shock absorber, part number 8040 1088, is designed for the rear of a wide range of vehicles, including classic models like the 1989-1991 Avanti, many Buick and Chevrolet cars from the 70s and 80s, and even some later models like the 1992-1996 Buick Roadmaster. It’s a twin-tube, low-pressure gas shock that’s internally adjustable for rebound, meaning you can fine-tune how quickly the shock extends after compression to get the ride feel you want.

The red paint finish is a classic KONI look, and the internal adjustability is a notable feature that sets these shocks apart. This adjustability allows you to dial in the damping to match your driving style or specific road conditions, offering a more controlled and comfortable ride than a standard, non-adjustable shock. KONI shocks are built to last, and this model is a solid option for anyone looking to refresh their vehicle's suspension with a component that offers both performance and durability.
