Hey guys, Does anyone have any knowledge of what kind of bags I would need to lift it a few inches and lower back to stock height? Would helper bags accomplish this or do they only lift it when it is compressed?
The factory coils are compressed. All coils are. If you wanna raise it from and lower it to stock, you'll just need the right size of bag. Just know that it will ride really firm the higher you go (more pressure in the bags) and you'll be that much closer to the max extension of your shocks. Rough estimate is that you can go up as high as 2" on stock shocks. This is dependent on your driving environment/conditions.
Call Firestone and/or Airlift. They have a lot of bag size options. You'll need to measure the clear distance inside your coil, from the pocket in the frame to the plate on the axle, with the weight of the vehicle on the axle. Jack it up by the differential and set the axle on jack stands. You'll also need to know the clear inside diameter of your stock coil.
