Will this work with my stock shocks, or do I need to replace them?

Stock shocks can typically handle 2" of front lift without immediate failure, but they'll compress faster and wear sooner. Many builders pair a leveling kit with quality aftermarket shocks to get the ride quality and longevity you want. That's up to your budget and how hard you drive.

Do I need a rear lift too, or can I run this alone?

You can run it alone, but your truck will rake backward (nose up, tail down). A matching rear lift keeps the truck level and balanced. Most owners add rear springs or a rear kit at the same time to nail the stance and handling.

What do I need to install this myself?

Basic hand tools and a jack. Since it bolts to factory points, you're removing stock components and swapping in new hardware. A torque wrench is smart—refer to your vehicle's service manual for fastener specs. No alignment needed after install, but a once-over at a shop never hurts.
