Recently I obtained a grant for our police department and purchased a set of Stinger Spikes from Federal Signal. The Stinger XL is a compact, lightweight, easy-to-use tire deflating device that is extremely effective in stopping pursuits involving large vehicles including large
trucks, farm vehicles, and military-type vehicles. Stinger spikes are hollow. This allows air to escape at a controlled rate without causing a blowout or sudden loss of control. The spikes are 2.1" in length and are made of 304-T7 stainless steel. The XL’s new 2.1" length spike acts in conjunction with our patented rock-and-tilt mechanism base. This Stinger technology effectively penetrates thicker tires to safely and quickly end pursuits involving many larger vehicles including large trucks, farm vehicles, and military-type vehicles.

The Stinger XL’s 15 1⁄2' wide system covers multiple traffic lanes and is furnished with replacement spikes, safety tip guards, and a spike replacement tool in a compact, quick-deployment carrying case. Additional Stinger replacement spikes are furnished free of charge. For incredible pursuit stopping power I highly recommend the Stinger Spike System.
