Pro Comp Coilover Spring and Shock Assembly

Pro Comp PRO-VST Coilover Spring and Shock Assemblies

When off-road enthusiasts talk about upgrading their suspension with a coilover spring and shock assembly, the goal is always the same: more travel, better damping, and a ride that holds up whether you're crawling rocks or hammering down a highway on-ramp. Pro Comp delivers that combination through its flagship PRO-VST (Vehicle Specific Tuning) coilover line — a series engineered from the ground up for trucks, Jeeps, and off-road SUVs that demand real-world performance.

What Sets the PRO-VST Coilover Apart

Designed for maximum off-road capability, the 2.5" PRO-VST Monotube Shocks and Coilovers are constructed with a hard-anodized thick wall impact forged body, and feature 17-4 PH stainless steel precipitation hardened shafts that are chrome plated for maximum corrosion and abrasion resistance. That combination of materials isn't accidental — it's what separates a trail-ready coilover from a street shock dressed up in off-road clothing.

With Vehicle Specific Tuning (VST), Pro Comp PRO-VST shocks are specifically tuned for maximum ride quality on-road and pro performance off-road. This means the valving, spring rates, and shock geometry are dialed in per application rather than relying on a one-size-fits-all approach. The result is a coilover assembly that feels at home on daily-driven lifted trucks without sacrificing capability on the trail.

The 2.5 body outer diameter is paired with a full bore piston to maximize damping capability, while a 6061-T6 impact forged aluminum body provides increased strength and lower shock temperatures. An internal floating piston separates nitrogen and oil to improve damping response and eliminate cavitation. For demanding off-road use — where heat buildup and fade are real concerns — these engineering details translate directly into consistent, fade-free performance across long runs.

The T6 aluminum shock body is lightweight but strong and can dissipate heat more quickly than other materials, while a hard anodized silver finish protects the shock absorber from corrosion, keeping it in great shape for mile after mile of service.

Vehicle Coverage and Fitment

Pro Comp's coilover spring and shock assembly lineup covers a wide range of popular off-road platforms. Fitments include applications for the Ford Bronco (front VRST and rear VSRT pairs), Chevrolet Silverado 1500 4WD, and other late-model trucks and SUVs. These units are tuned specific to the vehicle application to maximize ride quality and suspension travel, which means you're not guessing on spring rates or shock stroke — Pro Comp has already done the engineering work for your specific platform.

The Pro Comp Promise Warranty

One of the most compelling reasons to choose Pro Comp for a coilover upgrade is the backing behind the products. Pro Comp Suspension products are backed by what they call the Pro Comp Promise — if one of their suspension products breaks, not due to misuse, neglect, or vandalism, they will replace it free of charge. Whether you are the original purchaser or not, Pro Comp promises to make it right, and this coverage extends to all suspension products including shocks and steering stabilizers. For a component as critical as a coilover assembly, that kind of transferable lifetime support is a meaningful differentiator.
