What is the primary benefit of the long fin design on this reservoir?

The long fin design significantly increases the surface area of the reservoir. This allows for more efficient heat dissipation from the shock fluid, helping to prevent shock fade during prolonged, hard use.

What size shocks is this reservoir intended for?

This reservoir cylinder is designed to be compatible with King Shocks that have either a 4.0-inch or 4.5-inch diameter body.

What material is this reservoir made from?

The reservoir cylinder is constructed from aluminum. This material choice makes it lightweight while still offering good durability for off-road conditions.

Product Details

What you get with this King Shocks part is a 16-inch long reservoir cylinder designed for 4.0 or 4.5-inch diameter shocks, featuring a 4.5-inch outer diameter and a long fin design. This reservoir is constructed from aluminum, making it lightweight and durable for demanding off-road use. The long fin design helps dissipate heat more effectively, which is crucial for maintaining consistent damping performance during extended periods of hard driving, like long desert races or challenging trail rides. King Shocks is known for its robust construction and attention to detail, ensuring that these reservoirs can withstand the rigors of off-road abuse.

The 4.5-inch outer diameter means this reservoir is intended to pair with larger King Shocks damping units, typically found on performance off-road vehicles where increased fluid capacity and heat management are critical. The long finned body increases the surface area exposed to the air, aiding in cooling. This is important because shock absorber fluid can heat up significantly under heavy use, which can lead to a decrease in damping effectiveness, often referred to as 'shock fade.' By providing a larger volume of oil and a more efficient cooling surface, this reservoir helps to keep the shock oil within its optimal operating temperature range, leading to more consistent and predictable handling.

When installing this reservoir, ensure you have the correct mounting hardware and follow the manufacturer's recommended procedures for connecting it to your shock absorber. Proper installation is key to its performance and longevity. This reservoir is a solid option for anyone looking to enhance the cooling capacity and overall performance of their King Shocks setup.
