Can I add HD towing package after market

Recommended Posts

Posted (edited)

Hello there.  New this this forum. Nice to meet you all.  I just bought a 2017 Yukon XL SLT.  I thought the towing capacity was 8300, but now that I'm reading more it looks like around 6300 without the HD towing package. We're looking at a travel trailer that is 5050 dry weight and 600lbs toung weight.  Seems like the Yukon can handle it even with adding water, but I wonder if it worth trying to add the HD towing package?  Is there an aftermarket way to do it or do I need to go a dealer? Any idea on the upgrade cost?

Nothing you can change or add will change the factory tow rating. It is what it is when the vehicle is built.

Thanks for the response.  Not trying to add addition tow capability, but trying to get to the max capacity of 8300 tow. Everything I'm reading shows the standard tow capacity to be 6300 for the Yukon XL out of the factory, but there is/was a HD towing package option for my model and year that will upgrade a few things to handle additional weight. Larger rear axle, upgraded cooling, different spring on back, (which I think is what silveradosid mentioned above), et . Was just curious to see if that can be added after by the factory or if there is a way to add those after the fact?

Anything can be added but at what cost?   


Lager axle means the whole rear assembly will need to be replaced and brakes may not be same either so more cost.

Upgraded cooling means replace radiator and other misc parts

Different springs will also require different shockes

 

Could cost $5,000+ if having to buy all new GM parts......Be better off looking for another vehicle equipped like you want because you still have a 5.3L engine.

Apologies for the slow response.  Thanks for clarification. Makes sense.

So I am kinda in the same boat.  I am looking to pull a travel trailer around 5700 pounds.  I wanted to upgrade my 2018 Suburban but can't find a way to do it like other manufacturers do.  It may cost $2500-5000 dollars to do it but believe it or not, my depreciation would be more than that to trade for a newer better equipped one for.  Any suggestions o increasing capacity?  I did add an aftermarket Curt brake controller that made a world of a difference.  I have the Premier package on the vehicle, so I like all the bells and whistles of the car.  The axle ratio is the problem at 3.08.  Thank you in advance.

If the trailer is more than the tow rating of your burb, then there is no upgrade to make it legal to tow.
