I'm not sure if this will work on my 05 dakota but here goes and any advice would be great. I bought these adjustable helper springs ( http://www.sup-auto.com/catalogs/rideeffex.pdf) to help in the sag while pulling my trailer but as u can see the axle in the pic is above the leaf spring but my axle on my dakota is under the leaf springs, so can I install them like they say still and will it work for what I want, I don't want to lift the back end any just don't want it to sag, thanks everyone!!!

 

That should work regardless of where the axle is since the mounting of that "helper spring" doesn't interfere with the spring mounting to the axle. That bottom one that goes right across the entire spring probably wouldn't work, but there are other bolt-on helpers for a spring-over that wouldn't require disassembling the spring-to-axle connection. You didn't mention how heavy your trailer load is, but don't expect a whole bunch out of these half-spring add-ons, you may be better off with air adjustable shocks for the occasional time you pull a trailer.

 

I put the Monroe Load Levelers on mine, and they work great. Fairly easy installation, too.
