i currently have a 49 f1 with a front drop beam, disc conversion, floor mount booster, ordered everything for a power steering swap, and the rear end has the rear shackle flip and front mount moved up. the truck sits good now but i want lower. basically my question is how much lower will the front be with posie dual lef kit. and on the rear will the posie springs work with the reverse eye on the set up i have currently. i do not wanna flip the rear end unless i have to.

 

You may want to do a search on here on mono and dual leaf springs. A fair percentage of those that tried them were not pleased. Depends on how you drive. Have you removed every other leaf out of the OEM stack to see if that gets you low enough? If you want to go lower, I see a dropped axle in your future. Not that much different cost from new springs and a better choice.

 

Ive got a dropped axel now. I want the front about 2 inches lower and rear about 3 inches. Idk if removing every other leaf will work and I'm not 100 percent sure on how to do it.

 

Pulling leaves out is the oldest trick in the book when it comes to lowering/softening ride. It'll do something and its worth a try for you, especially considering the only cost is your time. I don't have the time right now to walk through the process but someone else here should fill you in. It's not terribly complicated.

 

Posie's Dual-Flex front springs will typically give you a 2" drop over stock height. Whether or not your current original springs are already saggy is to be determined. You start running into steering geometry issues when using dropped springs with dropped axles. So be aware of that.

 

I wanna take some out of the rear for sure. The truck is about 7 inches at the front of the step and 9 in the rear of the step. It's not the best way to measure it out. I want the back to sit level or about am inch of rake so I'll start there. Thanks for al the help
