Most Pusher Products will be a special order and can take up to 2-3 weeks for delivery. If you need it sooner, please contact us for our stock levels!

If one turbo on your Duramax works well, then a second will make it work great! Whether you keep your stock turbo as the atmosphere for that daily driveability that you're used to or upgrade to a BEP/Borg Warner unit, you'll get power up top that will drastically increase your Duramax performance! Compounds are not just for go-fast power though, they'll noticeably increase your trucks towing useability, fuel economy and lower your EGTs often over 200F.

Pusher turbo kits are unsurpassed in quality. If you're doing this kit at home, when we say every bolt/wire/clip/bracket is included for assembly we mean it. The R&D that has gone into each pusher kit is unrivalled to make this one of the most comprehensive assemblies out there. It doesn't matter if you're a professional in a shop or a hobbyist having fun in the garage, parts that don't fit suck!
