Shock relocators needed?

[JVictor75]

So, my CPP shipment came in today (12 boxes - almost 600 pounds) and going thru what I got versus what I ordered, I realized that I didn't order the front/rear shock re-locator kits. (I also didn't receive my 2 degree axle shims or my front calipers, but I have a note saying that the calipers are on back-order ATM. I'll have to call about the shims.)

I'm doing a 3.5/5 static drop on the truck: 1" lowering spring + 2.5" drop spindle in the front / 4" HD lowering spring in the rear (I know I said rear was going to be a 5" drop, but this is on a longbed and is what was recommended by both CPP tech support and ECE tech support.)

My gut says yes, the re-locators will be required if I want the shocks to work their best. Am I right?
