    OK, I had the option of spending $3,000 on a D60 and other stuff or get a boat - since the K5 does not float that great I got the boat. The thing weighs about 5,000 lbs. and the question is:

    When towing a boat this size, what should I look for in rear springs? I am about to install my new 14 Bolt and I plan to install a Rough Country 4" lift kit. Will these springs and shocks be enough or should I start looking at helper springs or a air bags? Thanks.....

    Now I have two money pits ------

  3. I went with the same lift kit on my Suburban with the intent of towing. I think the Rough Country springs are a little stiffer than most, so I thought they would be better ideal. You still may need helper springs/air bags depending on how your Blazer squats. Also a weight distributing hitch may work better to help cut down on sway if you have any because of the short wheel base of Blazers.

    I use the stock springs with an 2" add-a-leaf and 4" blocks right now. No problems, but I dont like blocks for towing. That and my boat dosent weigh near as much as yours. Mine looks like this one: http://www.v-driveboat.com/rides.php?action=viewride&amp;id=19
    But mine has the headders sticking out like the top pic.

    If you don’t drive with the boat at the hook each day, you should pay attention to good handling without trailers. If the handling with trailer should be inakzeptabel, than go to install airlifts or hijakers.

    @ fireinthehole,
    The handling with trailer is about alike with the Blazer and Suburban. The Burb looses his advantage of the longer wheel base by its long overhang.

    Are you trying to get flexy with the K5 and use it for towing? I'm trying to get flexy with my Suburban and tow with it so I went with a 4" block and a 2.5" add a leaf. It's done well so far. I tow a lot of cars and trucks on a 25',2300lb car hauler.
    If you just want to tow I would go with heavy duty lift springs, a load leveling hitch, trailer brakes, and some sort of sway control. I used to do towing duties with my K5 but anything over 5000lbs would manhandle it. I also found that some 3/4 Trailering special Chevy's came with a rear sway bar. That could help too. The short wheelbase can make towing a real chore. Good luck.
    Here's a pic of the trailer behind my od K5.
