What's a good sub/amp combo?

Whats the difference between a lift kit and a combo kit?

• I was wonderin the difference between a lift kit and a combo kit? I wanna raise my 2001 F-150 up and not pay a ton. I was thinkin about 4"-5" and I recently stumbled upon combo kit and like the pricin on those, but arent familiar with them.

• Answer:

  combo kit usually have the torsion keys and a lift kift. torsion keys level the truck then lift, of course, lifts the truck. keys are $100 and 4-5 inch lift kit is around $1000. so if you can find a combo for less it's a good deal. http://www.roughcountry.com/suspension/4wd-ford/f150_97-03_lift-kits.html
