I need to get a dually to pull a potential triple outboard boat. I need to know which years are preferred in used Chevy Duramax Allison diesels.

I read where the 2006 to 2007 LBZ Duramax are good.

I read where the brakes on some years (?most years) are the weak point?

Could informed hulltruthers give me the good and bad points of the used Chevrolet Diesels.

you want the LBZ. big HP and torque with no emissions crap along with the 6speed allision. the LB7's has injectors issues and some of the LLY's have overheating problems. get the LBZ, u wont be sorry, screw that emissions crap/

The 01-04.5 is the LB7 motor, known for injector issues, but I've seen rigs with 250K on them with no issues. It wasn't the motor, but the injectors from Bosch that were the issue. I have 120K on my LB7 and no issues at all with injectors. They all have more power then you'll most likely need, not many boats you're going to tow weigh what this truck was built for. The earlier body style, from what I've read is a little better on fuel, I know I got better than my friends 09.

I've replaced the injectors in my '02, 3 times so far... about every 80,000 miles or so. My brother also has an '02 and his first set lasted about 150,000 miles.

The LB7 has plenty of power but if it's going to be a daily driver I'd avoid those years (01-04). If it's just going to be a tow vehicle, you may get a good deal on one of the earlier models and being that you wouldn't be putting tons of miles on it, you may never see an injector problem.

Not sure about the newer models but the brakes on mine are awesome. My first and only front brake job was at 150,000 miles. My first and only rear brake job was at 233,000 miles. I tow a good bit - mostly in the 7,000-10,000 lb range and my truck stops 10k lbs, no problem.

I think the brakes have been basically unchanged until the release of the 2011, I could be wrong though. I have an 05 and at 90K miles the pads are still like new. The Allison is great for brake life BTW.

Most, (not all?) of the complaints about the brakes on GM HDs are from up north where the salty roads can rust the calipers up IMO. The rust tends to bind them up more then usual for what ever reason. Keep everything clean and freed up and they're great.

BTW 2005 LLY 90K never over heated and no problems, no complaints and paid for :)

One more thing, if you're going to tow over 7K, get rid of the factory hitch unless it's a 2011. the factory hitch on the earlier mods is for a 1/2 ton, lots of guys have had cracks and broke welds, bent hitches. Go to a Curt 15602.

06-07 Duramax is your best bet HOWEVER, they only put the LBZ in some of the 06's. You have to check the trucks vin number, as long as the 8th digit is a "D" its an LBZ. All of the 07 Classics came equipped with the LBZ.
