Question:

Hello, I am wanting to reduce the squat in my 2003 chevy avalanche 1500 when pulling my gross 6800 lb. camper. Can you tell me the pros/cons vs. airbags in the springs and the bump stops? NOTE: my truck has the coil springs and not the leaf springs

The pros and cons for the Air Lift air bag suspension enhancement kit part # AL60769 and the Timbren part # TGMRG25C is that the air bags are a bit higher maintenance since they require managing air pressure in them and you have to deal with the (pretty low) risk of developing a leak but they do offer infinite adjustability and won't affect ride quality when not needed.

The Timbrens are a much simpler install and require zero maintenance BUT they are known to be pretty harsh especially when unloaded. So if it were me I would go with the air bags as I value ride quality over simplicity.
