X31 Vs. Z71 Off Road Package?????

[Sierra Dan]

Anyone know the difference?

I think GMC is calling their off road package X31 now, and not Z71 for 2019 to further distinguish between the two "brands".

Yeah I just saw this in an email from GMC talking about the new Sierra.  Here is a link with mention of it on the Elevation press page as well and you can see the decal in the picture there:

Kind of surprised as Z71 is such a known name now.  The AT4 sure looks good in the email pics they sent.

So GMC has the AT4 and X31....

Chevy has the Trail Boss and Z71....

Wow, I like the looks for the X31. Can you get a 6.2 in it?

[shift_grind]

It's a sle level truck, so no 6.2.  They say double cab only but we have seen it in crew cab so the jury is out on that.

X31 = Z71.

Z71 Off-Road Package, includes (Z71) Off-Road suspension, (JHD) Hill Descent Control, (NZZ) skid plates, (K47) high-capacity air filter and Z71 hard badge

 

AT4 = TRAIL BOSS.

Both AT4 and TB use RPO Z7X:

TB is Custom and LT versions, AT4 is based on SLT, AT4 offers the 6.2, TB is 4.3 or 5.3 on Custom, 5.3 on LT TB.  Adds some differentiation do GMC even more from Chevrolet.  Same for GMC using X31 instead of Z71.  X31 is available on all trims except Denali and AT4, Z71 can be had on WT to High Country, and you can add the Z71 appearance/protection package on Chevy.

Good Info newdude.

Is there any comparison of the actual differences between the "high-capacity air filter" in the Z71 vs. non-Z71 stock air filter?

On T1 yes.  Different filter for K47 high capacity and w/o K47.  Also, the air box does have a different p/n with or without K47.  All the ducting is the same.   

 

1999-2013 they used to offer two different filters, one with K47 one without K47.  Same air box with or without K47.  GM consolidated it to one single replacement filter in 2014 to just one p/n, the high capacity design 22845992.  So 1999-2013, the GM only offers the high cap. filter.   

 

Whats funny...is on K2 trucks, they still option K47 high capacity, yet there is only one filter part#.  2014-2016 use the 1999-2013 filter, 22845992, 2017-2018 use a new p/n 23349854, but both filters are spec'd with or without K47.  And they have the balls to include it in snow plow prep option as a "feature".

I will be curious to see if the K47 High Capacity Air Filter will be interchangeable with the standard filter as in years prior, or if the air box is different now on the 19s.

Looks like the only way to get the K47 option is with the X31 off-road or VYU Snow Plow Prep package.

They very well might.  Z71 also gets K47, so VYU, Z71 and X31.

The X31 package is $850 for the Sierra which includes Hill descent control, Skid Plates, High Capacity Air filter and X31 badging, wonder what the badging is?

Also included 2 speed transfer, p265/65 15 All terrain tires and Dual exhaust!... Interesting 

[Sierra Dan]

The badge is the same as Silverado Z71 in style and color, but reads X31

Ah but it gets more interesting.

 

Z71 and X31 vary in price based on trim level.

 

Silverado WT/Sierra Base:  $945

 

Silverado LT/Sierra SLE:  $1545

 

Silverado RST/Sierra Elevation:  $1245

 

Silverado LTZ/Sierra SLT:  $850

 

Silverado High Country:  $350

 

Denali does not get Z71/X31 this time around.

Z71 and X31 should be cheaper if you have a 6.2 (they already have dual exhaust and 2 speed transfer case) as 850 is a lot if you have the 6.2, but cheap if you have the 5.3.
