ok so I purchased a 5th wheel and have a 2000 f150 (HD) I guess they called this truck a f250 light duty in 99? anyways I was looking at some helper springs online and need to know the width of the leaf, while looking a few minutes ago I noticed that the front section of the leaf sits pretty flat and not curved like the rear section, then I noticed the front brackets have a 2nd set of holes that could possible move that end up which would curve it more. Are these adjustable ??

 

Not adjustable. And yes, if your truck has 7-lug wheels, it was known as the F250 light duty for 97-99.

If I may make a suggestion of air bags rather than helper springs. Not that helper springs don't get the job done, but they make the rear ride pretty rough. Air bags can handle more load without sacrificing the unloaded ride quality. Plus you can adjust the pressure from side-side if needed.

Other options are something like SumoSprings, but it's a matter of preference.

I looked at both those products and it is not much more $$ than a good helper springs system, Thanks for the info. from reviews on the bags seems like everyone is pretty happy. of course I will have to go low end and fill with a small dc air pump when needed.

 

That's really all you need. They hold a lot less air than a tire, so they are very quick to fill. When I use them, I just take my portable air tank or a 12v compressor. They're really cheap.

I have the Firestone air bags on my truck and they're worth every penny. I've used helper springs and coil-over shocks on other vehicles in the past, but didn't like the harsh ride and awkward handling. It was weird having the front normal and the rear stiff. Just didn't feel balanced. But matter of opinion.

 

I recommend the Roadmaster Active Suspension system. Basically it is a coil spring that attaches to the back of the leaf spring and the U-bolt. As the leaf compresses, it pulls on the coil spring. It also acts as a sway bar.

Just ordered the load lifter 5000 for mine. Really excited to get them on and try with the travel trailer

 

Air bags are the only way to go!
