Compatible with 1988-1998 GMT400 Series (OBS) Pickup - Extended Cab w/o 3rd Door

If you own a classic OBS truck, then you know that often times the inner rocker panels will become severely rusted over the years. More times than not the best choice is to replace them. Holley Classic Trucks has got exactly what you need with our inner rocker panels for the 1988-1998 GMT400 series extended cab trucks. These inner rockers have excellent fit just like the OE, as well as better corrosion protection due to the EDP coating. They are manufactured with heavy gauge steel for superior strength and have the quality and fit that your project truck deserves.
