Rudy's Upgraded Allison Transmission Cooler Lines For 06-10 GM Duramax LBZ/LMM

If you're running a 2006-2010 Chevy or GMC 2500/3500 with the 6.6L Duramax (LBZ or LMM), these transmission cooler lines from Rudy's are a solid upgrade.

They're built with heavy-duty 5/8-inch hydraulic hoses rated at 300 PSI working and 1200 PSI burst.

That means way less chance of leaks and cooler transmission temps.

The kit comes with three lines, two concave washers, and a fittings/hardware kit.

It's a direct fit for 2006-2010 trucks, but heads up: if you've got an OE replacement radiator, the fittings might not play nice.

You might need metric adapters (sometimes called Setrab).

These are performance parts, made to last.

Comes with a 1-year warranty.

Keep your Allison cool and happy with these beefed-up lines.
