Yep, looks right. I didn't have the "BILF4" on the beginning, but the rest is the same as my order.

I just put those on my 08 last week. Yes, that's the p/n.

 

 

And hows the ride? No not in the Pitts, in the truck?

The ride is much much improved over my stock Z85 (heaviest OEM springs and heaviest OEM shocks) shocks. The stock front shocks didn't have enough damping and the frontend floated and bounced around like a bobblehead doggie doll in the back window of a 65 Impala. The rear bounced up and down like a streetworker on a jackhammer. Now, it's got a darn near car like ride. No bouncing or bobbling. I do have a shell/topper on mine, so your mileage may vary, when it comes to the rear.

My truck is smaller, but I too noticed some improvement around town, lots of improvement over speed bumps and rough highways, and its a whole new truck off road.

Last I heard all 1/2 ton trucks have the same springs, the Z-71, Z-85, Z-66 is all determined by shocks.

 

***EDIT*** After a quick search I can see no difference in the Z-85 and Z-71. Both have 1.81" diameter shocks, the Z-71 does have 'larger' jounce bumpers (bump stop)...

 

***EDIT*** After a longer search I found some conflicting information, disregard my shock sizes noted above.

For the rear there were 4 different shocks.

The NHT Max trailering Pak w/Z85 suspension crewcab has a 7300 lb GVW (4wd) with a max payload of 1921 lbs and 7100 lb GVW (2wd) max payload 1965 lbs. The Z71 crewcab, I think, has a 7000 lb GVW (4wd) max payload 1674 lbs and 6800 lb GVW (2wd) max payload 1652 lbs.

 

I believe I looked a my rear springs vs a standard crewcab and they were different. I'll check again, as there are a few standard crew 1500s in the parking lot at work. I would guess the fronts would be the same, but don't know.

I didn't think about the NHT equipped trucks, but the others, are all the same spring, I think four shocks is correct, I can't verify exact sizes but they were standard, trailering, sport, offroad. I am fairly certain the offroad (Z-71) shcok is largest, followed by sport or trailering (Z-85, Z-60) then standard (Z-66), don't hold me to any of this though. Not to mention I don't know where NHT falls in (I thought it was the Z-85).

OK, via the chevrolet website the shocks on a Z85 truck are 46mm, the shocks on a Z71 equipped truck are 1.81" (46mm). The website does not describe the Max trailering package "Heavy duty/trailering suspension" any differently than the standard Z85 which is the "Heavy duty/trailering suspension" of half tons with out the max trailering pack. It appears to me as far as shocks are concerend there are only two sizes being issued, regardless of how its named. Standard size and large size (1.81"/46mm). I'd bet the explanation for the higher ratings on the trucks equipped with the max trailering pack is the different rear axle. The website also makes no mention of different springs, but I do see they are all rated at the same capacity springs and rear axle at 3,950 lbs.

 

Beats me, all I know is whats under my truck, and shocks aren't a big deal to me except the ones I want to put on it (Bilstein and they are on sale now!)

Andy,

Yeah, I could never figure all the variations out either. I know my front swaybar is 36mm because I measured it. That corelates to the published GM information for Z85 and Max Trailering Pak. I think the standard swaybar was 32mm and the Z71 was 34mm. But, all this information seems fuzzy.

 

If I think of it, I'll just duck under a similar crewcab with standard suspension and look. There are at least two here at work.

The Z71 "off road" pkg gets 46 mm shocks and 34 mm front sway bar.

 

The Z85 "handling/trailering" pkg gets 46 mm shocks and 34 mm front sway bar.

 

The NHT pkg gets the Z85 pkg, 6.0 engine, 9.5" hybrid axle, 4-wheel disc, & HD tow pkg.

 

The "HD tow pkg" is an option for the Z71 and Z85, but all of them I've seen around here have it (mine does).

Well done! Thanks. But what's in the HD tow pkg? I wonder if I have it. Is that the Z82? Cuz I have that but can't remember what's in it.

      The Peckish Synapse

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?
