Last fall we announced our new leveling and SST lift kit offerings for the all-new GM 1500 trucks. We specifically did not include the factory lift kit-equipped GMC at4 and Chevy Silverado Trail Boss.

The AT4/Trail Boss are factory equipped with a 2-Inch front lift. This front lift includes a longer front shock/strut assembly.

When combining a traditional leveling kit on these factory lifted trucks, several issues present themselves including binding problems with the factory control arm ball joint and contact concerns with the lower strut/CV axle assembly. The 69-3920 SST Lift Kit works with the factory 2-Inch front lift.

This kit includes a top mount strut spacer along with a pre-load spacer to limit droop and the same premium grade upper control arms now available in our 66-3921 leveling kit. OE style 3-Inch tall cast iron rear lift blocks and rear bump stop extension cups are also included to create a true AT4/Trail Boss-specific bolt-on lift kit that provides 2-Inch of front lift and 1-Inch of rear lift.

This new lift kit concept is similar to our successful TRD Pro Plus 2 SST Lift Kit which is also engineered specifically to work with that factory OE suspension lift. Your trust in ReadyLIFT to provide high-quality, precision engineered products is extremely important to us.

You can be assured that this all-new SST lift kits are the absolutely most reliable and best performing suspension upgrade option for the AT4/Trail Boss trucks. AT4 - Max tire 305/55-20, 20x9 0 offset wheel Trail Boss - Max tire 295/65-20, 20x9 0 offset wheel Note: Use of Auto 4 HI feature not recommended..

Looks good so far, will update once installed
Have not installed this yet, so this is only a first impression review. I bought it to use in the wheel well area on my truck, so I’ll update later once I actually get it on and see if it makes a real difference. So far it looks good out of the box and seems straightforward enough. One thing I’d recommend is making sure you have a sound deadening roller for install, because I would not try putting this on without one. Too early for me to say how well it works for road noise since it is not installed yet, but I wanted to post my initial thoughts for now and will update later.

Great product, very impressed
Looks good, adhesive grabs well, forms well to floor pans. Price is great will be ordering more again. It definitely deadened the tin can sound you can get.

Solid Product, lots of it too
Ive had the insane rattling from my subwoofer and the highway drone from my aftermarket exhaust, and this 80mil sound deadening mat was the exact fix I needed. The 36 sqft kit (which comes as 33 pieces) was plenty to fully cover my trunk, rear deck, and floorboards. Since it's a butyl-based material, there’s no awful asphalt smell, and it adhered incredibly well with just a simple roller. The difference is honestly night and day. My bass hits so much tighter and cleaner now without the whole back end vibrating like a tin can. Even better, the cabin is significantly quieter at high speeds; that aggressive exhaust drone is finally muffled to a deep, tolerable purr. If you want an affordable way to upgrade your audio quality and actually hear your music on long drives, I highly recommend this! It took some weekend elbow grease, but the payoff is incredible.

Would recommend
Size: 10 sqft
I used this sound deadening material in my car during an audio and interior upgrade, and the difference was noticeable immediately. Road noise, vibrations, and rattling were reduced a lot, especially on the doors and floor panels. The car feels much quieter and more solid while driving now. The material was easy to cut and apply, and the adhesive stuck very well without peeling up. It has a quality feel to it and conforms nicely around curves and tight areas. I also noticed my speakers sound cleaner and have better bass response after installing it. For the price, this sound deadening material is a great value and definitely worth it if you want a quieter ride and better overall sound quality in your vehicle.
