Looking for better traction and more suspension control? Summit Racing has a variety of new products to offer just that, including the Yukon Gear and Zip Locker, which allows you to go from an open differential to fully lockable by flipping a switch. These lockers are built for both on and off-road use and work using air pressure to offer a variable locking action. If you are looking for this kind of diff control, check out the Summit Racing website, but beware – you’ll be bewitched by the enormous variety of performance products on show!
