I've tried to search the forums for some good direction, but didn't have a lot of luck. I have an 05 Z71 1500. I want to add a 2" leveling kit and I need new tires as well. Once I put the leveling kit on I want to put the largest tires on possible. There a lot of differen't leveling kits out there, what my best option? Tires? Thanks for you help!

take your pick really. I just ordered the Rough Country kit. Others get the Zone Offroad kit. There are a few others. I havent seen any bad reviews for any kit.. On this forum at least.

 

Just put "level" in the search box and have at it. You'll get at least 5-6 pages that will help you out.

If you have an '05 model, I would just crank the torsion bars up, and see how much lift that gives you. It may be enough...and won't cost anything...except for the price of an alignment afterwards. If your factory bars have sagged too much, then you can look into re-indexed torsion keys, which will give you more lift from your stock bars. I wouldn't go any more than 2". What size rims are you running?

Gotcha. A 285/70/17 would fit easily (ran them on my '06 with just a t-bar crank)...and a 295/70/17 would probably fit if you kept the stock rims. I've also seen guys run a 33x12.5x17 with aftermarket keys and a little trimming...but those wouldn't be ideal for your stock 7.5" wide rims. If ride quality and MPG are more important, you could run a 275/70/17, which is available in a 6 ply (most 285's are 10 ply). A member on here (dirtfan21) has them on his truck, and I think they look great.

Well thank you there buddy!! ^^^

 

To the OP, I have stock keys cranked around 1.5-2" and I still have about 1" of rake. The reason I haven't gone the re-indexed key route is because my angles now are within my comfort zone and I really don't want to go more. I went with 275/70/17 Cooper ST's because my truck goes affroad quite often out in the fields and I didnt want to chance rubbing. Plus, with the 6 ply my MPG's barely took a hit. You could fit a 285/70/17 but in off camber situations it may rub.

 

My advice to you would be crank your stock keys and see where it get's you. If they are a bit tired then pick up a set of keys and crank to where you want, no more the 2-2.5".

i have an 03, and i got a 3" leveling kit and rear AAL from fat bobs garage. factory keys cranked will not level the truck.

 

as for tire size, you can probably fit up to 305's but i think that 285's are a good size and it looks proportional. any bigger then that it really kills MPG and the way the truck drives.

 

sig picture is 285's and leveled without rear AAL installed

Thanks a lot you guys! This has helped out a ton. Dirtfan21 that is almost the exact look I am going for. Again I appreciate the help and I will post some pics after I get things done.

Looking forward to the pics!

Yup! Seeing your truck is the reason I went with my 275/65's, which is the 18" equilivant to yours. They look much better than stock, the 6 plys ride nice, and MPG is very close to stock. :thumbs:

 

 

factory keys cranked will not level the truck.

 

Sometimes it works, sometimes not. My '06 sat dead even with the stock keys cranked...and still had a little bolt left. My buddy ran his all the way up on his '04, but it still sat .5" lower in the front. Go figure.

Well it took me a little while to get back on here with an update, but I've made some changes that I'm pretty happy with. First I did the Rough Country 2" leveling kit. I decided to go with Cooper Discovery AT3 285/70/17. I love how good it makes the truck look! While I was at it I de-badged the tailgate and removed the pinstripes. I also installed new Rockford Fosgate speakers. I've been busy!!

35s will fit if the aftermarket torsion keys are fully cranked with minimal/mabe no trimming...buddy had a Z71 tahoe with just keys and he had 35 inch rocker radials which are actually bigger than a true 35x12.5

 

37x13.5s will fit with a 3 inch body lift and keys

 

33s will fit with little to no lift and it will give you a good look without totally killing your mpg

 

I say go with 35s !

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...

      Different requirements for oil filters?

      // Thank you, also for your  response. More information is always good. This 2013 GMC is most likely my 'forever truck"-I'm 77 and retired...and truck only has 42K on it-very clean-so I try to keep it that way.  Tks again for your  response- glenn

      Alternate wiring for Kicker sub with Bose system. (DO THIS)

      By smooth68 · Posted

      I started my install this weekend. Everything was pretty straight forward but I ran into one issue with running power through the firewall. The nipple grommet on my High Country already has a small harness running through it - has anyone else ran into this issue? And on the engine bay side, does the wire basically just penetrate the factory wiring boot? I did this on my '22 Trail Boss and it seems much easier but thats been a few years. My other thought would be possibly drilling a new hole adding a rubber grommet just to the lower left of the factory hole. Thoughts?   Has anyone used a T-harness off the Bose amp and obtained power from there? It seems a little odd that such a small amp needs 3 power leads

      Different requirements for oil filters?

      By glenn27 · Posted

      ///// Ok--Thanks for that info--I could not find yesterday when I looked for the specs on that NAPA filter what I wanted. Their website is not very user friendly. I buy all teh filters for  our three vehicles once or twice a year. Have always run NAPA Gold on everything I own....I buy it thru my Son's account for his business-which he has a Heavy Equipment repair shop-one reason he uses NAPA so much-they have such a full line of coverage for just about anything/anywhere- He gets s  good discount because of volume bought. Anyway-Thank you -Sir for your response.   glenn
