Z71 vs Z85

Difference?

Z71 vs Z85

Postby MouSe [OP] » Oct 02 2011, 3:13am

So, while I'm over here in Korea my GF buys what I thought was a 2004 Crew Cab Z71. However, when I run the VIN through CompNine it says it has the Z85 suspension package on it. So, is the only difference between these two the shocks and skidplates? Or, is there more differences to them?

The Z85 is a suspension upgrade (because a towing package) from a quick google search.

They are technically both upgrades from the base suspension though.

Very true, one for towing and one more set up for off road.

I just built up an SLT with the "Heavy-duty Handling/Trailering Suspenion Package" which I am pretty sure is the Z85 (there is no code on the website, the general public could care less). It has...

-44mm piston monotude shocks
-36mm front stabilizer bar
On SL models, requires available Trailering Package on Crew Cab models; standard on Extended cab models. On SLE and SLT models, includes 36 mm front stabilizer bar when available Max Trailering Pack is

I will dig deeper to see to see if this is actually the Z85 package or not. If I was not deployed I would just check my window sticker for you but I do not have it with me in the desert.

Just checked out the Off-Road Suspension package which is the "Z71" package so I am going to go on the assumption that the Handling/Towing package is the Z85. The list of upgrades to the Z71 is...

46mm High-press gas-charged shocks
36mm front stabilizer bar
Off-road jounce bumpers
Skid Plates
High Cap air cleaner
Z71 stickers
Recover hooks (2WD models)

The specs might be a little different since these are for the 2011 models, but I am pretty sure the options aren't that much different.

Meh, I'm lifting the dang thing anyway. Doesn't really matter what it has from the factory I guess huh?

Hehe, it' already looks like a truck. Whoever had it first put on nerf bars and some meaty tires on the factory 17s.

Nope, if you change out springs and shocks you have pretty much gotten rid of the Z71 suspension leaving you with stickers and skid plates and a little bit bigger sway bar in the front.

I do 99% highway driving and I currently have a Z71 package. What is the best option to get a smoother highway ride and less bumpy ride. Any input would be greatly appreciated.
