Don..... Cutting springs is the cheap and easy option,but certainly not the best.
Don't get me wrong,I've done it myself.(It ruined the ride in my old Vauxhall Cresta)

It looked cool tho'!
The problem is,it will affect the spring rate and also ride quality. Most spring are designed to be progressive through their compression range,cutting will affect this.
Save your $$$$ and buy a pair of the correct springs.
You know it makes sense!

Your truck will thank you for it.

Why don't you contact TCI and see what they suggest?
Good Luck
Jock.
