Sorry but I'm new to lift kits and just to make sure and ask someone it will fit my 2000 chevy tahoe ls correct?
Nope, wrong one. That one is for a 2500 Series Suburban or Yukon XL with the rear leaf springs. There were no 2500 series Tahoes or Yukons, they are all 1500 series, and have rear coil springs.
If your existing front end parts are in good shape, you just need leveling keys to raise it up 2-3". Any E-bay keys will be fine. I got Ford leveling keys and put them in my last Suburban (doing the same on my "new" '04 Yukon XL), and managed a full 3" with barely cranking the keys at all, for just shy of $35 shipped (most Chevy keys are about $45, and will get you up to 3"). For the rear, I went with Z71 springs from RockAuto ($57), and E-bay 2" spacers (under $40 shipped). Brought me up to 39 3/4" fender height in the front, and 40 1/4" in the rear, on 285/75/16 tires. Added new shocks in the front (2-5" extended length KYB Monomax's), and stock length KYB's in the rear, with 2" spacers. Bilosteins are a very, very popular option.
The only thing else I'm doing this time around is adding extended length swaybar links (Jeep JK 3" lift, 11.25" center-to-center) off E-bay for about $20.
