    2003 GMC Sierra Performance Parts Reviews

    ProRYDE Torsion Bar Keys
    The ProRYDE keys work exactly as described. I have an 03 Silverado Z71 1500 with 6" lift and a great big bumper with a 12,000 lb winch. My torsion bars were starting to sag a little so I purchased the ProRYDE adjustable keys. They work great. They are slightly clocked different than the stock keys and have much more adjustability due to the design. I'm very happy with my purchase.
