    I have a 1995 GMC HD 1/2 ton and looking for a way to keep it level when pulling my 20 ft. trailer.

    Helper springs, air bags, or buy replacement leafs for the 3/4 model and bolt em up to the 1/2 ton.

    just remember that you are not increasing your load rating....just the spring rate.

    also check you trailer balance. if you are towing a 2000lb trailer, your tounge weight should only about 10-15% of the trailer weight.

    Another thing that could affect your ride is the hitch height

    Also, your current springs are 10 years old, I'm sure they are tired...and your shocks are probably due for replacement. If it was me. I'd try new shocks first...

    no matter what, you looking at 3 bills, for springs and shocks...

    More springs will give you a stiffer ride without the trailer + jack your rear end up too. We put Firestone Air Lifts, with an underhood compressor and incab gauge and controller in our F250's. Now you have air with you whenever you get a flat, and the luxury of a smooth ride when not loaded. But I do agree, your springs may be tired, and thats not helping your case. BTW, that setup cost us about $800 installed-well worth it in my opinion.

    Helper springs will not affect your unloaded ride characteristics.

    Air shocks would probably be your least expensive approach.

    If your 'helper springs' refer to adding additional leaf springs, I disagree with your statement as I added additional leaf springs on a few trucks and the end result was a bumpy ride and the tail end was in the air when not under load.

    I am not referring to an add a leaf (adding more springs to the existing leaf pack). A helper spring (some call them overload springs or camper springs) mount on top of the current leaf pack and do not come into play into there is weight added to the truck. The do not increase the ride height or ride quality.
