Looking to add some stability to the rear end & less sag when I tow heavy. I had a set on my 250, but don't know what works good on my 150. I'm not looking to add lift as much as just less sag. What works best? I've heard the Pro Comps are good.

 

SuperSprings work well and are easy to install.

 

I think most AAL's add height. I was looking at FatBob's and they said between 1.5" to 2.5".

Have you looked at Roadmasters Active Suspension? There was a group buy earlier this month for them.

 

X2 for the supersprings.

had them on my 2004 f150 FX4. Really helped a lot when carrying the atv in the bed while pulling my trailer.

 

I added a leaf on my 2003 Tundra which raised the rear about 1.5". The SuperSprings on my F150 only raised the rear about 3/4".

 

Husky Spring offers many options for your rear suspension. You can get a modest 1" AAL spring kit that will add 1,000 lb payload capacity. They also have other options available. Here is a link: http://www.huskyspring.com/2009-2011...its_c_143.html
