KA2717 / KA2717 - Application Notes You've probably been reading about the new SS Silverado in all of the truck magazines. STILLEN is giving you a jump-start on converting your Silverado into an SS months before the vehicles will be available to the public. We're taking it even further. We are also building bumper cover/spoilers and roll pans for the earlier body style C/K Trucks. So, whether the truck/SUV is an '88 - '98, '99 - '02 or current body style (2003), you will be able to build your own 'SS'.
