Looking for stiffer front springs

I have a 2012 TRD crewmax and just installed a Frontier Gear front bumper/grill guard combo. It's heavy and dropped my front end about an inch or so. I'm looking to see if there are any stiffer spring options out there that aren't too pricey. I've read on here about OME, Bilstein, and others but I'm trying to find cheaper options. A stiffer factory spring would be ideal but I don't know if they make any stiffer than what's already on my truck. Thanks in advance for any suggestions.

 

Dobinsons C59-610

 

What’s your budget? Twin tube shocks from OME and Dobinsons are pretty cheap and can come with 650 or 700 rate springs. Stock I think is 600

 

If your shocks are original, replace them anyways

 

Thanks for the suggestions. I'm hoping to keep total cost for springs and shocks under $500 if possible.
