  1. Hey I have a 99 Silverado with a 4” lift if I put these on will it be a total of 7” lift in the front??

  2. I have a 2004 avalanche with a 6 inch rough country suspension lift. Would I be able to add this leveling kit for more clearance on my front tires

    • Adding leveling keys will certainly lift the truck up more but you may run the risk of going too high and maxing components out.

  3. If i have a 3.5 suspension lift and put these keys on the truck will it total out to 6 inches? 95 silverado 1500 4wd

  4. I have a 97 k1500. Could I run 33’s on a 20×14 with these?

  5. Hey I have a 06 Chevy 1500 and wanna put 20 inch rims with some 33s on it will this leveling kit allow me to do that?

  6. when you guys say “lift 3 inches over factory” are you referring to the height straight from factory of the height with the factory torsion key maxed out?

    • Up to 3″ over OEM ride height, depending on application. It will go higher than OEM torsion keys, but not 3″ beyond the OEM max adjustment setting.

  7. will this kit fit 33x10s with a -24offset on a 2001 chevy Silverado 1500 4wd

  8. I have a 2001 GMC Sierra 1500 4wd. What kind of suspension lift/level do I need to be able to fit 20×12 -44 with 305/55s with only plastic trimming, no metal.

  9. Will this allow me to put 20×12’s with 33’s on my 2004 GMC Sierra 1500

  10. Can use coil spacers and these

  11. are there any shocks you would advertise to go with these keys in case i didn’t necessarily want to use the spacer provided with the keys, but might be due for new shocks sometime in the near future? I have a 2005 avalanche LT

  12. Will this allow me to fit 35 inch tires in the front with minor trimming?

  13. I have a 97 Silverado with 20″ Juice Pacer rims and 275/60/20 tires. No lift kit right now. The tires had a slight rub when they were new but I trimmed the valance and took care of that. If I put this leveling kit on the front and possibly 2″ blocks on the rear, how big of a tire can I go with? Thanks

  14. I’m picking up a 2003 Chevy Avalanche today. 1500 Z71. Will this affect how the vehicle rides? I have some experience in suspension work but don’t fully know.

  15. Will this set up fit on a 2005 yukon denali

  16. Hello, first thank you for very clear information and great videos for these products. I looked into them years ago and decided against them due to the drive angle and ride quality issues but ProRyde seems to have eliminated those problems. I have a 05 Z71 Avalanche and it’s on “aftermarket” GM 22″ wheels (im sure you know it came with 17″ from the factory) with 285/45 Dueler AT Revo 2s. I know that this kit has the potential of a full 3″ of lift over factory, but i only want to level my truck, whether that’s using .5″ or 2.5″, so (typically) what is the largest 22″ tire i can fit ? I know it partially depends on the sag in my stock springs, but what is your recommendation? I don’t “wheel” it hard but it does go hunting and get pushed hard in deep snow and im fine with grinding a little bit of plastic, but i don’t need the absolute biggest tire either, but would still like to know my options. I would like a somewhat aggressive tread, though. I think the “lifts and levels” said that about a 33×10.50-11 ” wide tire was max, but i thought id ask directly with my exact model before ordering. Thanks for your help and assistance.

    • Sorry guys, just watched the video again and it gave my answer i believe. It said a 32×11.2 or a 275/55 but i wasn’t sure if they were 22s or 20s but I’ll start researching and let me know if I’m on the right track.

  17. Will the fit a 2004 Chevy avalanche z66 2wd

  18. will they fit 2004 Z–71 Avalanche .

  19. Will these give me more lift than my rough country ones? Didn’t gain nearly as much as expected from them.

  20. will this fit on my 2004 silverado z71? my plan is to put a leveling kit and some new rims on but i want to make sure this will fit with no problems.

  21. Will these fit on a 2006 duramax? I know you guys have these keys specifically for a 2500hd but im wanting to put 1500 keys on it to get a little more lift. Can i comfortably get a full 3 inches out of these keys because im getting a 7 inch FTS kit and wanted the front to sit at 10 with the back at 8 on 37’s

  22. would this lift fit on a 2wd Silverado?

  23. Do you have any pictures of this being used on a 2001 tahoe?

    • We don’t really have truck specific pics but a leveling kit will bring the front of the truck level with the rear. Takes the rake out of the vehicle. Does that help?

  24. I want to get the advertised 3″ higher ride height up front out of this kit. I understand that if I do so my front end will be sitting higher than the rear. What else would I need to get my 2005 Gmc Sierra 1500 sitting 3″ higher and leveled?

  25. How much for installation?

  26. what do I need to get both front and rear leveled?
