Finally got time to install the Alcan springs
we bought the truck a few years ago for it to be my then 16 year old sons daily driver, it had stock springs
We bought a parts truck that had 14 bolt and 8 lug Dana 44
And it has a 4” suspension lift of unknown brand
Springs in front and blocks in back
Since this is a daily driver
We installed a junkyard LS 5.3, a NV-3500, vintage air AC etc
We recently ordered some springs from Alcan , 4” front , tears with no lift and a rear shackle flip kit from ORD
And new rancho RS 9000 shocks
Wow!
This rig went from riding worse than some of my 18 wheelers to slightly more firm than my 06 expedition
Soft enough that we had to re install the front sway bar
Rides better than the stock springs
If you want some good riding springs ,
These are the ones
Lessons learned :
Buy all new bolts for the springs and shackles
You will likely have to cut some of the bolts because they are rusted to the bushings so hard that no amount of pounding with a BFH will remove them
Get a lot of high quality blades
Each blade is good for one grade 8 suspension bolt
The shackle flip kit was a PITA
We used a plasma and grinder and lots of hammering with chisels and punches
We used a friends warehouse at their business on a day when they were closed
We didn’t think to take any measurements doing any flexing using the forklift
We were too tired and just wanted to go home
Took us appx 11 hours
