Firestone Sport-Rite 2320 FAQ with SD Truck Springs

Q: I have a 2005 Chevy Silverado, will I have to drill anywhere when installing this kit?
A: Yes, For this kit drilling is required into the frame of your 2005 Chevy Silverado. Exact specifications and measurements are located in the Instruction Manual but as a general rule of thumb I would advise to make sure no electrical or brake lines are in the way before you begin to drill.

I have only a jack and a few jack stands, these things were a cinch to install. The directions are a bit tough to read in places, but its easy to figure out. Everything worked exactly as it should have. The hole drilling really is not as big of a deal as I would have thought. Took me about an hour and a half to do both sides. Once installed, I can level the truck out easily with a couple pounds. I rented a camper that had a healthy tongue weight, and I had 30 psi or so to get it to sit level. Bags work great!

Outstanding product! It was easy to install and works like it's supposed to. I installed it to help raise the rear and provide more stability when pulling my car trailer. There was a noticeable improvement in all aspects of driving. The truck felt much more stable with the bags inflated to about 70-80 psi. I highly recommend this kit. I've been using it about a year and still works fine with no leaks.

Overall, the install was not difficult (as long as you're a moderate DIY'er), just needed to purchase a new drill bit to use on the truck frame. The airbags were exactly what was needed for my half ton, leveling it nicely (almost max tongue and trailer weights), which made pulling our trailer safe! A t-valve fitting was supposed to be delivered with my order, but never showed up. After calling customer service, Justin found the error, and had it shipped out the same day! Overall, excellent product (multiple uses and almost 1 year after initial install), and SD TruckSpring customer service was fantastic!

Ths is a great product! the install took a little longer than the instructions indicated, but the instructions were easy to underatand and the outcome was better than expected! I tow a trailer and this product improved the ride very much. Much better ride and it feels better braking. It also has been useful when carrying a heavy load in the truck bed by leveling the truck. Great product, would not hesitate to recommend this to others.

Air bags were very easy to install. I like being able to adjust the support. It works out well for the variety and weight of things I tow. I no longer get the swaying I was experiencing before I installed these air bags. I want to thank the knowledgeable salesperson for pointing me in the right direction.

This kit installs very easily and the ride height is perfect. The suspension feels very good, even better than before, handling around corners is better. Obviously much better hauling and no sag when doing heavier loads. I had the truck bed off when I installed the kit so it went a lot smoother, about 1 1/2 hours total install time and that was taking my time double checking everything. Anyone can do the install , just take your time. Best money I ever spent on the truck!!!
