Best ride quality, Stock or Lifted?

[BigRed76]

ORD emailed me back today, they said they don't make a 2.5" shackle flip for the 67-72 trucks because they weren't comfortable with the strength because of how much higher the shackle mounts are in relation to the frame. If you look at the 4" shackle flip bracket for 67-72 you can see that the shackle mount just barely hangs down below the frame, so to do a 2.5" shackle flip it would put the shackle mount almost directly beside the frame rail.

I have yet to find the stock leaf spring rates. But here is a table that lists several leaf spring rates.

My plan for my 78 k25 is the 2" tuff country ez ride front springs, and hafl ton pickup springs from 98-2000 chevy/gmc pickup. They are 63" long and if you have ever ridden in a truck like that, you know they ride amazing for a fullsize pickup. And the fact is, its a factory leaf spring designed to be used in a pickup. They are obviously lighter duty since they were OE in a half ton, but hafl ton srping capacity is good for most folks. Heck my 2012 GMC 1500 has only 3 leafs but is rated to tow like 9500lbs. It rides amazing as well.

So, ez ride springs, good shocks, and longer rear springs and i think i'll have the best possible combo of smooth ride but still good stability.

Also, not sure about the 67-72 stuff, but TnA offroad offers a zero lift shackle flip for the 73-87(91) crowd.
