What is the purpose of the external reservoir on this shock?

The external reservoir holds extra shock oil, which helps to keep the shock cooler during operation. This improved cooling leads to more consistent damping performance, especially during hard use or over rough terrain.

What does 'smooth body' mean for this shock absorber?

A smooth body shock has a clean, cylindrical design without external coils or complex housings. This makes it less likely to snag on obstacles or collect excessive mud and debris off-road, simplifying maintenance.

What is the typical application for a shock like this?

Shocks with external reservoirs like this one are commonly used in off-road vehicles, trucks, and SUVs where improved damping control and heat management are needed for demanding terrain or higher speeds.

Product Details

King Shocks is well-known for making robust suspension components for off-road vehicles. This smooth body reservoir shock absorber is a prime example of their focus on performance and durability. It's designed to offer improved damping control over standard shocks, helping your vehicle handle rough terrain more comfortably and predictably.

This particular shock features a 4.0-inch diameter cylinder with an external reservoir, measuring 13.25 inches in extended length and 3.46 inches in outer diameter. The external reservoir allows for increased oil capacity and better heat dissipation, which is crucial for maintaining consistent damping performance during extended use or under heavy loads. The smooth body design is also less prone to collecting mud and debris compared to some other shock styles.

When you're looking to upgrade your suspension for more demanding off-road adventures or just want a more controlled ride, this King Shocks unit is a solid option. It's built to withstand the rigors of off-road driving, offering a noticeable improvement in how your vehicle absorbs impacts and maintains stability.
