Skunk2 Coilover Spring and Shock Assembly

Skunk2 Coilover Spring and Shock Assemblies: Race-Proven Suspension for the Street

Skunk2 Racing has built its reputation on delivering motorsport-derived suspension components that perform equally well on the daily commute and the race circuit. Within the Coilover Spring and Shock Assembly category, Skunk2 offers a tightly engineered lineup centered around two flagship systems — the Pro-S II and the Pro-ST — each representing a different tier of adjustability and track focus while sharing the same core engineering philosophy.

The Pro-S II: Precision Without Compromise

The Pro-S II is Skunk2's full-threaded-body coilover solution for enthusiasts who want meaningful suspension upgrades without diving into full competition damping adjustability. Each Pro-S II system is built around a mono-tube design featuring a forged threaded body that allows ride height changes independent of spring preload, with precision valving dialed in by Skunk2's suspension engineers for the spring rates specified for each application. This separation of ride height and preload is a critical feature — it means you can slam your car for show or dial in a balanced stance for track use without upsetting the shock's intended performance window.

Skunk2's micro-polished, mono-tube design and one-piece forged shock bodies, combined with precision-machined oversized shafts and pistons, ensure that each Pro-S II coilover is both responsive and durable. On the spring side, Pro-S II coilovers feature hard-anodized, CNC-machined, forged 6061-T6 aluminum spring perches and CNC-wound racing springs manufactured from high-quality SAE9254V spring steel. Each spring is designed to optimize the balance between comfort and performance and is custom-matched to its respective shock.

The Pro-ST: 12-Way Adjustable Daily-Driver Performance

For drivers who want more granular control over their suspension tune, the Pro-ST steps up the game with damping adjustability. The Pro-ST features a 52mm seamless carbon steel shock body, a mono-tube damper with high-pressure nitrogen, synthetic shock oil, 12-way adjustable precision damper valving from street to track, and Chrome Vanadium SAE9254V-spec racing springs with independently adjustable ride height and spring preload.

The large 52mm seamless carbon steel mono-tube shock bodies provide added strength and accommodate a larger hydraulic piston and valves, more shock oil, and an enlarged nitrogen chamber. Quick and precise ride-height adjustments can be made for dialing in corner balancing as well as for improved handling, responsiveness, and overall balance, while Skunk2's track- and street-tested Pro-S II shock valving offers the perfect balance between daily driving and track performance.

Construction Details That Set Skunk2 Apart

• Forged, shortened and threaded shock bodies with super-finished hard chrome shafts and reduced shaft stroke for full travel on lowered vehicles.
• High-quality polyurethane bushings maintain precise handling and feedback, while a padded spring seat at the top and nylon thrust washers at the bottom of each spring reduce friction, eliminating noises commonly found in many coilover systems.
• Threads are gold-colored and the body is coated with protective zinc electroplating for smooth adjustments, further protected against the elements by powder-coated mono-tube lower mounts.
• All Skunk2 race springs are CNC-wound using the highest quality SAE 9254V spring steel, shot-peen stress relieved, and corrosion-protected through powder coating and specialized phosphate treating processes.

Engineering Backed by Real Racing

All Skunk2 products are carefully planned and designed in-house using the latest computer simulation and modeling techniques, followed by careful testing in controlled laboratory environments. Each product is then subjected to rigorous dyno, street, and race track testing to ensure proper performance in the most extreme conditions. This development loop — from simulation to street to circuit — is what gives Skunk2 coilover spring and shock assemblies their dual identity as capable daily drivers and credible track tools. Whether you're building a clean Honda Civic street car or preparing an Acura RSX for weekend track days, Skunk2's coilover systems offer a well-validated path to better handling dynamics.
