Tilt Sentry bars are one of the only, if not the only, bars on the market that we know of with a thrash resistant lifetime warranty. When a company stands behind their product like that, you know you're buying quality. Sentry bars have a standard outer diameter and can be used with either a standard or baby SCS. The Sentry bars have 5 degrees of backsweep and 1 degree of upsweep. These bars aren't for everyone - they're tall and wide. At 24 inches wide and 27.5 inches tall, you may need to cut them down a little bit if you're on the smaller side. All in all, these are phenomenal SCS bars and, with the lifetime guarantee, you can't go wrong with the Sentry bars.
