99-07 3/4 and 1Ton HD 4WD
6"
Suspension Lift Kit
This is one of the best designed kits for the HD GM2500 on the market. Jack-It's experts love the 1 piece heavy duty lower sub-frame made from 1/4" steel because it eliminates the squeaking and popping problem. The new steering knuckles allow for stock rims to be used as long as you retain a stock width tire. We haven't found another knuckle designed kit that you can run stock wheels on, which can save you a lot of money since purchasing new wheels isn't necessary. The new knuckles also allow you to retain the full stock steering system instead of reverting to the drop center link design, which has been the source of many steering problems.
This kit includes differential drop brackets and axle spacers to keep the CV axles at proper geometry, extended sway bar links, lateral compression arms with brackets that give the kit increased fore and aft support when using your truck offroad or snowplowing,rear blocks and U-bolts that are specific for this truck. These blocks wrap aroud the spring perch just like a factory block does and you will not need to double stack the rear blocks, they're big enough! This kit also includes front and rear SX8000 shocks with black boots, a carrier bearing drop bracket (incase you have a two piece rear shaft, which all crew cab models have).
Jack-It's favorite thing about this kit is that it gets rid of the "dog tracking" look. This is when you look at the truck from the rear and you can see the front tires sticking out further than the rear tires. This kit only increases the front track width on your truck by 3/8" per side, which is the least amount of any knuckle kit out there. Most will increase it 7/8" per side! That's almost 2" total, and it's noticeable. Not to mention most people that buy a lift want wider tires anyway, which makes it all the more noticeable. Some customers have informed us that people had flagged them down while they were driving to tell them there was something wrong with your truck like, "you need to get your alignment checked," or "Something has shifted on your suspension, the truck doesn't track straight." That won't happen with this kit, which is why Jack-It has it's approval stamp on this Tuff Country kit. It is a great design, includes detailed instructions for install, and all the hardware needed is included. Plus you get Jack-It's low price guarantee.
