Hey Peterbilt owners and mechanics, if you're dealing with worn-out door latch issues, these replacement striker pins are exactly what you need! This APPERFiT set comes with two pins (one for each side) that directly replace OEM part numbers 20-12972, 2012972, and HLK2128. They're designed to perfectly match the original factory specifications and dimensions, so installation is straightforward with no modifications needed. Made from high-quality materials, these striker pins are built to withstand the demanding conditions truck doors face - daily opening and closing, vibrations, and weather exposure. They're compatible with 2005 and earlier Peterbilt models including the 330, 335, 359, 370, 378, and 379 - covering most of the popular classic Peterbilt trucks still on the road. Over time, the original striker pins can wear down, causing doors to not latch properly, rattling, or even failing to stay closed - which is both annoying and potentially dangerous. These replacements restore that secure, solid closure you expect from a Peterbilt. The quality is impressive - they feel substantial and well-made, not like cheap aftermarket parts that might fail quickly. The company stands behind them with a 1-year warranty, and their customer service is responsive if you have any questions or issues. Whether you're a professional mechanic working on customer trucks or an owner maintaining your own rig, having these on hand can save you from being stuck with a door that won't close properly. Seriously, for the price of two quality replacement pins, you're getting peace of mind and restoring your truck's door function to like-new condition!
