A Low-Cost Twin-Tube Steel Racing Shock for Racers Looking for Consistent Performance
Lap after lap, race after race, you need racing shocks that can take the abuse and come back for more without being a strain on your racing budget. You need high-performance steel bodied racing shocks that are dependable with plenty of valving options. PRO Shocks’ WB series of twin-tube steel body shocks are just what you’re after. With a 2-inch diameter body that features a coilover ready snap ring groove, strong 9/16-inch hardened shock shaft, superior, yet economical gas cell design, and a multitude of compression and rebound options, the WB series of sealed steel racing shocks offers racers true value for their racing program. For coilover conversion simply add either our 5-inch or 2.5-inch diameter spring coilover sleeve/conversion kit.
The benefits of a twin-tube shock design in racing when compared to a monotube are what makes them perfect as dirt track racing shocks. The lower gas pressures found in twin-tube shocks not only provide lower friction on seals but translates to these shocks often having a lower rebuild cost, saving your racing budget. The lower gas pressure also allows the internal valving to be followed more smoothly at lower speeds, which allows the shocks to break free with smaller inputs where grip is critical, making weight transfer smoother and providing more progressive damping, which equates to more driver feel when comparing to a monotube shock. These lower pressures also produce less extension force, or preload, on the shock itself. The steel body is more tolerant of minor racing inflicted damage, protecting the internals and allowing the shock to continue working through the rigors of racing.
Multiple Compression, Rebound, and Stroke Lengths Available
PRO Shocks’ WB series of steel body racing shocks are not a one-size fits most product. We offer a multitude of compression and rebound options along with stroke lengths of either 7- or 9-inches to provide the precise shock specifications your racing program needs. These compression and rebound valving options are fixed into each sealed shock. So, while rebuilding or valve changes are not possible, the lower cost of the WB series allows racers to carry multiple shock options in their trailer for immediate race day changes for track conditions. Add in the pre-installed 1/2-inch spherical rod end mounts and you can certainly see the value in the WB series of racing shocks. These shocks are approved for use as dirt track racing shocks in many IMCA, USRA, and WISSOTA classes and are perfect for dirt and asphalt racing programs such as IMCA Modified, B-Mod, Pure Stocks and others.
