Hey Jerry, thanks for reaching out!

I've got a SuperSprings kit that will work for your 2007 Silverado 2500, but the kit you referenced is for a 3500 model.

For your truck, you'll need the kit # SSA15MXKT which fits as long as you don't have the factory top overload springs. If your spring stack height is greater than 2-3/4" over the axle, then you'll also need to special order some 5-1/4" U-Bolts to make these fit.

Are you looking to get more control while towing/hauling?

I want 4,000 lb capacity. Do you have that? Or is this an additional 3,000 lb on top of the current payload?

@Jerry The 3K capacity of the kit # SSA15MXKT is the largest that will fit your vehicle when it comes to the SuperSprings. We could get you a higher weight rating for suspension enhancement if we go with a different type, like air bags, but this is the highest rated SuperSprings kit in the "leaf" style for your truck. It's important to note that the weight rating for all of the suspension enhancement parts is just for what the kit can help handle. It won't increase the weight rating of your truck at all. So if your truck is rated for 4K payload then the SuperSprings mentioned above will help with 3,000 of it whereas an air bag kit rated for up to 5K would be able to help with all 4K of it, if that makes sense. Are you willing to go with a different suspension enhancement type?

@JonG I already have airbags on my truck. I didn't know they changed the load capacity. I looked up the bags and I have 5000 pounds of load capacity. I also have the big wig sway bar and some other hardware attached in between my springs, so I think I am good. Thank you for your time.

@Jerry Happy to help out! Just to be clear - the air bag kit doesn't change your load capacity - they only help your OEM suspension handle the weight better.
