??Replacement for old bags. Works greatLifts the car easily and rides great.. Very happy would highly recommend.. Easy to installYes. Fit my 1968 c10. Don’t forget the air hose and fittings.Worked great for me on my Silveradoamazing airbags!!!!! Best choice for the money.They are the most disappointing set of bags I have ever purchased . I have been riding airbags since 2002 and I am certified to say this . I sliced both bags by one side to side where the center ring got ovaled and cut through both fricken bags the third day of riding on em. Slam Specialties by far is not only a better product their safety alone makes them the best idea for anyone who has passengers or cares even alittle about themselves or other motorists for that fact ! Not a joke when you ruin someone else’s life because your equipment fails and most likely they won’t even understand how special your vehicle was before crashing into their crossover or whatever pos they drive . Rant Over I wasted money on these and that is how I feel about it.
