For 2006-2010 LBZ/LMM Duramax trucks, this transmission cooler line kit replaces factory fluid lines with nylon-braided CPE hose and -10AN fittings for a secure, high-flow connection.
2006-2010 Duramax Transmission Cooler Line Kit
Every truck owner knows that it doesn't matter how powerful or reliable your engine is if you can't get any power to the wheels. The transmission mated to your 2006-2010 LBZ/LMM Duramax is essential to everything your truck does, and keeping it cool is crucial. Upgrading your transmission cooler with a SPELAB performance transmission cooler is a good start, but the fluid still needs to get to the cooler. That's where this 2006-2010 LBZ/LMM Transmission Line Kit comes in.
These high-performance lines are constructed with a durable CPE that's wrapped in a high-strength nylon braid. This wrap prevents expansion and further protects the lines from abrasion. Finally, these lines are capped off with -10AN fittings for a secure and leak-free connection. Like all SPELAB products, these transmission lines are backed by our 12-month warranty.
