SCC Engine Guards are 1.5" thick to match the thickness of our handlebars. The guards like all our products are made in house and made of steel with a clean chrome finish or glossy black finish. The guards where designed using Harley-Davidson softail and bagger models that were completely stock. If you lower your bike please know that our warranty will not cover your bike. Any customizations to the frame may cause clearance issues. We ask that you go to a professional installer to ask if they can install and check for any issues that may arise when riding. If you have air ride in the front please make sure that your forks have a stopper inside that will prevent the front from dropping too low that it may hit the fender against our guard. Steady Custom Cycles will not replace or refund any product that has been damaged due to negligence to take the proper precautions before installation.
