Here is my first how to so be nice and don't hesitate to ask if you have any questions.
1) Lowboys front coil over kit (Thanks to my man here for the lead)
2) Universal perch purchased mine from summit racing
A lift is very helpful, a spring compressor is a must, jack stands, hydraulic jack and tools
Put your truck on a lift if possible to get under
Once in the air you can access the Ubolts and make room for the new perch
Loosen the Ubolts in order to make room to weld the perch
The Perch ordered were a bit small and needed slight grinding for a snug fit
Now you can line up your perch under the axle with the same angle as the factory on top of the axle
Once in place, weld them up
Now that your perch are welded on both sides under the axle, bolt your ubolts back up and head home to work on the rest
Now in a secure place, jack up the rear of your truck. Be sure to utilize jack stands and chalks to secure the truck and remove the wheeels
Here you can see the ubolts nuts ontop of the axle (Take 'em off)
Once Ubolts have been removed you can see the leaf spring bolt that will need to be reversed
Lower the truck and remove the front and rear bolts of your leaf springs.
Be sure to remove the brake line clamp for the rear. This makes it MUCH easier however there is a trick to removing the clamp on the brake line.
Now with the leaf springs removed you can reverse your leafspring nut so the nut in on the bottom of the leaf
Put your Ubolts back on Underneith and line up the Ubolt nipple to sit inside the perch hole and bolt everthing back up
Use your jack to push the leaf in place and tighten all nuts and bolts, don't forget to put your brake lines back.
All you have to do now is replace your bumpstops and put your wheels back on. If you want it lower you can add blocks now and or remove the payload leaf or run mono leaf.
