Zone Offroad 2001-2010 Chevy 2500/3500HD 3" Adventure Series Lift System.

This new addition to the Adventure Series lineup of lift systems is built around the Zone Offroad heavy-duty replacement upper control arms already available for the 01-10 HD trucks. The arms are made from 3/16" steel that is precision laser cut, formed and fully welded. Preinstalled MOOG brand ball joints and rubber bushings provide an easy installation and long service life. The ball joint is repositioned to compensate for the added lift and maintain a neutral position at ride height. To complement the improved upper ball joint angles, the kit address the other area often ignored at this lift height - the CV shafts.

The new Adventure Series kit for the 01-10 HDs includes a full differential drop system that relocates the differential down 2" for near stock angles at the 3" lift height. This is accomplished with a drop spacer on the passenger's side, (2) drop brackets for the front driver's mount and a integrated "half crossmember" for the driver's rear mount. A new different skid plate is included to protect the differential in its new position. The rear is lifted via a 2" block and u-bolts.

Front and rear shocks are included and can be upgrade to Nitro versions.


Fully welded, heavy duty upper control arms that dwarf the factory arms. Preinstalled replaceable MOOG brand ball joints and rubber bushings. Reposititioned ball joints to maintain a nuetral angle with added lift. Full differential drop system included to maintain proper CV shaft angles. Differential skid plate included. Rear height is adjusted with 2" blocks.

  1. Would this fit a 2003 Silverado 1500HD? My glovebox shows the FT2 FT3 RPO codes. Would love this with bilsteins 5100s.

    • Yes, the C31 kit will work for your vehicle. Unfortunately, this kit is only available with the upgraded Fox 2.0 Shocks. Thanks!

  2. Hi, i am wanting to buy this kit. Just wondering how much shipped it would cost? when i type in options it says $1433 with fox shocks, but i saw you responded to someones comment and said $1135 with fox shocks. Also the only thing holding me back from buying is i cant decide on the shocks….are the fox shocks really that much better than the nitro shocks?

    • Hello. When we responded previously with the price of $1135, that was when the kit was coming with the “Fox Adventure Series” shocks. They were a more economical Fox shock, but are now not available. The kit now can come with the Fox 2.0 Performance shocks, which are higher quality. They will give a ride quality better than factory. The “Nitro” shocks option will give a ride quality that is equal to factory. Thanks!

  3. I have an 05 2500 HD. Will I be able to run this kit and clear 20×12 -51 with 305/55/20. Truck already has leveling keys only. bumper trimmed and norcal mod have already been done

  4. I have a 2006 lbz Duramax. Can I fit 35×12.50r20 tires on a 20×12 -51 offset wheel? I don’t mind trimming.

  5. Will this kit fit my 04 2500

  6. I have cognito upper control arms and pro comp keys. Will this kit lift my truck more and make the CV angle better? I have 35×12.5 on 20×10 -19 and slight run at full crank

    • It probably wont lift the front of the truck any higher then you are now. But it will certainly help the CV axle angle with the diff drop used in this kit.

  7. I have a 2010 2500HD. I am curious if you know how big of spare tire I can mount in the stock location. I am looking at the 3″ Zone kit w/ 295/60/20 AT’s

    • I do not know a size for sure, not much larger then stock. Your best bet is to measure how room is under there.

  8. 2008 2500hd 4×4 diesel.
    has norcal mod , i was leveled on 20×12 on 33s, i have 22x14s if i get this kit would it work on 33s as well, -76 offset

  9. I want to use this kit on my 2006 duramax. Will I be able to use my 20×14 wheels and 35″ combo?

  10. What if my truck does not have any of the rpo codes in the glove box that match the example pictures? How do i go about finding the right setup for my truck? 2004.5 duramax lly

  11. What would be around average cost to have a lift like this installed and What do you think it would cost if i were to do everything except the diff drop myself?

  12. Can I fit 33/12.50/20 with the dropstars 655bm -44 with this lift on a 09 chevy

  13. I’m looking at ordering this lift but id ike to know if I can run the 33/12.50/ 20 ridge grapplers w/ 20×10 -44 dropstars 655bm wheels

  14. Ive been looking into this level lift kit for a while now, and I don’t want any rake on my truck so would I be able to run the 3 inch lift in the front and just replace the shocks in the back with no liftblock? Im looking for a little bit of lean so I think that would work out well on my 06 duramax

  15. Would i be able to run a 33 inch tire with 20x12s with this lift

  16. How is the ride if you don’t max the lift out to the full 3 inches and keep the cv angles relatively flat? Is it comparable to the stock ride height? Also by not installing the blacks in the back will it keep the truck perfectly level or will it interfere with the kit

  17. Would this fit a 2002 Chevy Tahoe

  18. Would this fit an 03 1500HD?

  19. How much is this lift with the Fox Shocks and do you carry this set up?

  20. Can i run a 33/12.50/20 tire on a 20″ x 10″ wheel with this 3″ kit on a 2005 chevy 2500HD 4×4

  21. Will this lift the truck higher than just adjusting the torsion keys

  22. Can you use the stock 16″ rims with this lift?

  23. with this setup what wheel size is needed to run wiyh 35s on this 3in lift and how much trimming is need?

  24. What rim and tire package do you recommend with the zone 3″ lift for an 05 sierra 2500hd. I would prefer an 18″ rim for a larger wall tire since I regularly drive on job sites. Thanks

  25. Is this a lift kit or leveling kit ??
