6 Liter Duramax Silverado and Sierra 2500Hd/3500Hd trucks with the Allison 1000 or 10L1000 10-speed transmission. They work with both the stock converter and most aftermarket performance converters, and they're the fix for stripped or snapped converter bolts. Converter bolts take a lot of stress, and reusing old bolts when you replace a converter or pull the transmission risks them loosening or failing.

A fresh set gives you clean threads and full clamping force.
