With very few exceptions all the front shocks (struts) are the same length as each other regardless of lift and whether they're stock or aftermarket.
(
Again with very few exceptions) all lifts for this platform either relocate the top of the strut with a spacer, change the distance between the bottom spring seat and the bottom pivot, change the coil spring or a combination of those things. What they
don't materially change is the length of the strut/shock.
I know you want to get this done right with the least money spent possible while still being done right. We all generally want that.
You might want to contact KYB and ask them about part number SR4550 -

That part is a strut, coil spring and mount combo that looks to be ecodiesel-specific. Looks like they retail for around $160/ea USD and if KYB confirms that the coil spring is ecodiesel specific that makes them probably the simplest click-and-done solution you're going to find because it's all one piece, labor will be minimal it's six nuts per side. (support frame, remove lower control arm inner nuts/bolts, remove strut lower bolt, remove strut upper nuts... strut falls out, yeet into dumpster, reassembly is reverse of disassembly, perform alignment, enjoy the drive) KYB is great quality, too.
The only possible gotcha on the KYB quick strut is if you still want to fool around with the height more than just what you'll restore from having the right springs, well they're not adjustable. If you want adjustable then you've gotta go with the pricier solutions Nick offered they're all good choices depending on your budget.
