Best way to lift k2500 suburban

I have a 1995 K2500 7.4l suburban. This year I started to notice more sag in rear end. Wondering what is best way to solve problem. Replace springs or add a air leveling kit??
  • Due to age, I would suggest replacement. Then maybe some bags to keep it from happening again (in 18 years :))
  • Cheapest would be helper coil springs. Pic is of my 1980 C10 Silverado

    IIRC, these cost around $59 bucks for the 1 ton...IIRC, the half ton were about
    $10 bucks less

  • Add a helper spring setup is probably the cheapest way to go. Under $200 for a set.
    Airbags are close to double that but have the benefit of adjustability.
    Timbrens are a little more than most of the helper springs and less than bags. They will not bring you quite back to OE spring arch though as they are designed to engage after a little suspension squat and do make the ride kinda harsh.
  • Basic set is set the psi and leave it, usually a schrader valve installed on the bumper or some place accessible with an air hose if you want to add air. You can add an onboard compressor and in-cab control with gauge so you can see what psi you are running and add/remove air on the fly.

    Airlift and Firestone are the two brands, look up your truck and see what they have available.
  • Are the airbags adjustable from cab or set psi and leave it?
  • I added Firestone Airbags to my Silverado. Easy install, works great. Easily adjustable for desired ride height.
