Pro Shock Shock Absorber

Pro Shock Shock Absorbers: Race-Proven Damping for Serious Builders

When it comes to shock absorbers built with genuine racing intent, few names carry the weight that Pro Shock does. Part of the AFCO Performance Group family, Pro Shock has spent over three decades designing and manufacturing shock absorbers that are trusted on circle tracks, late model dirt ovals, and high-performance street builds across the country. This is not a brand that dabbles in racing — it is a brand defined by it.

A Manufacturing Standard Built for the Podium

What separates Pro Shock shock absorbers from the competition is rooted in how they are made. Every unit is assembled and validated through a rigorous dyno process, where stringent tolerances are held from initial build through final quality inspection. This precision manufacturing environment is so respected in the industry that Pro Shock is chosen to produce private-label shock absorbers for some of the largest performance parts distributors in the world — a testament to the consistency and quality baked into every unit.

A Series Lineup Built Across Racing Disciplines

Pro Shock offers a thoughtfully tiered range of shock absorber product lines, each engineered for specific chassis setups, track surfaces, and competition classes:

• WB Series (Welded Bearing, Monotube): A steel monotube shock with a 2.000" OD body and hardened shafts featuring a removable rod end. Available in a wide range of compression/rebound valve combinations and compatible with a coil-over snap-ring groove — ideal for IMCA Modified-type race cars and late model applications, including Lightning Late Model Spec configurations.
• TA Series (Take-A-Part, Twin Tube): A steel twin-tube shock with a zinc-plated or black finish, offered across multiple stroke lengths from 7" to 9". The take-apart design allows racers to revalve in-house, providing hands-on tunability without sending shocks out for service.
• TASS Series (Stock Mount, Twin Tube): Purpose-built for GM A-Body, F-Body, and G-Body platforms in both front and rear applications. These steel big-body twin-tube units offer cadmium-plated corrosion resistance and are available in multiple valve configurations for front and rear tuning balance.
• TASB Series (Small Body Twin Tube): A compact 1.630" OD twin-tube option for tighter chassis packaging, available in zinc-plated steel with fixed valve configurations.
• A Series (Aluminum Twin Tube): Lightweight aluminum-bodied twin-tube shocks for racers who prioritize weight savings alongside performance.
• SS Series: A fixed-valve, steel small-body twin-tube rear shock designed for consistent, entry-level performance on stock-class vehicles.

Adjustability That Meets the Racer Where They Are

Pro Shock understands that different builders have different needs when it comes to tuning. Their double-adjustable shock absorbers allow both compression and rebound to be dialed in independently — compression via a thumb wheel and rebound via a simple hex key adjustment — making fine suspension tuning accessible even to entry-level competitors without requiring spring swaps or shock removals. For those who prefer a set-and-forget approach, non-adjustable options across the TA, TASS, and WB lines deliver consistent, pre-valved performance right out of the box.

Why Pro Shock Stands Apart

Pro Shock's knowledge of chassis dynamics — developed over decades of on-track testing and real-world racing programs — is embedded in every shock absorber they build. Whether you are campaigning a dirt late model, building an IMCA street stock, or refreshing a classic GM muscle car's suspension geometry, the depth of the Pro Shock lineup ensures there is a shock absorber engineered for your specific application, not just a generic fit.
