Snow Plow Prep

[wanna_try_gmc]

My truck didn't come with the snow plow prep but does have the HD towing.....everything I have reqad is there is really no suspension upgrades to the prep package, only beacon switch, high amp alternator and assorted miniscule things.....question is if I don't have the snow plow prep and put a plow on does that affect warranty??? I realize I'd need the higher amp alt to power the electric pumps now a days but I can't see anything that should be negating to the warranty as far as wear and tear from a plow. I'm thinking of putting on a Western 7.5......

Suspension is the same, and there is no reason why it should void your warrenty.

I don't know if this holds true for the newer models but crew cabs with sunroofs were not covered under warranty if they were used to plow snow. Something about the cab buckling IIRC.

I know in the past (GMT400s) the Z71 & VYU (Plow Prep Pkg) options spec'd the same torsion bars. I'm not sure if the current HD towing option torsion bars are the same as the VYU or not. There is a label on each bar (LXX & RXX). Left & right side bars are side specific.

For 2011, RPO CF5 (Power Sunroof) is not available on 2500HD models (either extended or crew cabs) w/ VYU Plow Prep. Since I only have 2500HD info on hand, I won't comment about the 1/2 & 1 tons.

 

The info should be found here:

I have the exact same truck ('09 2500HD ext cab Z71 6.0 short bed) w/ the snow plow prep package RPO VYU. Look under the truck at the torsion bars and there should be a tag with three letters on both of them.

 

You can also take a looks at your door sticker and see what FGAWR (front gross axle weight rating) that your truck has listed. The highest possible (before the front susepnsion redesign in '11) is 4800lbs (which is what mine with RPO VYU has).

 

Thanks to (sonjaab) here are the all the different torsion bars and there ratings. I'm curious to know your truck without VYU has the same torsion bars as mine. I have code GK (LGK on left and RGK on right). Let us know what you got.

For 2011 owners, I'll check the tags (& post what I find)on my new truck tomorrow if it isn't raining. It's a 2500HD w/ the 6 L & VYU.

Good luck with your delivery!

[revrnd]

Thanks. IIRC, my '04 had the GK bars as well. It was a 2500HD, 6 L & VYU as well.

[sonjaab]

Certain year GM trucks with the VYU plow prep also included extra

skid plate placement which were metal instead of plastic (think z-71).

 

Note that MOST dealers will deny any warranty repair due to snowplowing

on NON VYU plow prep equipped trucks. So be warned !

 

Ask me how I know !!!!!!!!!!!!!

[Stranger ranger]

in the 03 to 07.5 era trucks, the t bars are definitely more supportive on the snow plow prep equipped.

Found this out because my NON snow plow prep equipped hd with the bars cranked all the way has 1/4" of space between the UCA and the metal stop.

A friends Hd fully equipped with the package, with the bars fully cranked has at least an inch of space between the UCA and the stop, which equals such a nicer ride.

After comparing build sheets, the numbers showed true.

I checked the bars & they must be new for the new chassis. Tags don't match any of the listed broadcast codes listed. As per usual I've forgotten what the code is & it's dark out .

I'd be interested as to what your door tag says for the FGAWR (front gross axle weight rating).

[wanna_try_gmc]

ok....went looking......door tag show 4200 GAWR, but I show GK for torsion bars.....................also, I have the thick metal skids not plastic ones.....btw, why in the world did they not make an oil drain channel on the darn skid plate???? It's one PITA when changing the oil.....
