Short answer: No.I recently ordered an OME 2in Heavy Load Lift Kit, my stock drivers front shock has died.
My front shocks from the order have showed up but the springs and the rear shocks have been delayed by quite a bit.
Wondering if it's okay to replace the front shocks now to fix my issue, then replace the rest when my order fully shows up? Or do I need to wait?
If it were me, I would not use the new longer shock, particularly if your front springs are already sagged, because @ full compression of the spring The shorter distance in that circumstance, with the new longer shocks, the longer than OEM shocks would most likely be over-compressed and bottom-out, and likely get seriously damaged.
However you could look up the specs for both OEM and new shocks for the fully compressed measurement, and compare them to the new ones that you now have. I suspect the longer shocks will have a longer fully compressed measurement.
If you really need to replace one, you may be able to find one in a U-Pull or just get a new cheap one or a set of 2 or go to one of your local Parts Dealers, or Amazon, eBay Rock Auto, etc. I see prices in the low-range going from ~ $10 ea. on a Rock Auto Closeout sale to $50 ea and some pairs for around $50 in some of the places I mentioned.
