07-13 Silverado and Sierra Lowered Suspension | Performance and Looks


For Ridetech, an industry leader in truck suspension, this is the perfect time to release a new StreetGrip lowered suspension system for 2007-2013 Chevy Silverado and GMC Sierra pickups. Before Ridetech decides to design a lowered suspension system, we like to study the bones. General Motors’ 07-13 Silverado and Sierra pickup trucks have very good bones. Also, since the current generation, 2019 and up “T1XX” trucks are getting much of the attention these days,  7 to 12-year-old trucks have become a great value.

While these trucks are now two generations old, there is nothing antiquated about them. Also known as the GMT900 platform, 2007-2013 Chevrolet Silverado and GMC Sierra pickup trucks were heralded for their improved aerodynamics and all-new (for 2007) frames. The 6-speed “clutch-to-clutch” automatic overdrive transmissions were introduced in 2010. All of the LS-based V8 engines offer more than 300 horsepower, with the top-of-the-line 6.2L V8 producing 403 HP in 2013. We like to joke that these trucks come with “factory LS swaps”. Needless to say, these trucks are exceptional performers.

The StreetGrip system features adjustable coilovers up front, adjustable leaf spring hangers in the rear and adjustable shock valving at all four corners. You can fine-tune ride height to suit your wheel and tire combination and dial-in ride quality to suit your driving style. The front suspension can be lowered as much as 4″ while rear suspension can be adjusted to a 6.5″ drop. Drop spindles are provided in the kit, so a minimum 18″ wheels are required to clear the lower control arms. With that said, these trucks have plenty of room for wide tires.

One of Ridetech’s R&D vehicles is this V8 2WD standard cab GMC Sierra with 20×9 Black Rhino Stadium wheels and 275/45 Michelin Pilot Sport 4 SUV tires. Thick sidewall tires look great against the Sierra’s flared wheel arches. The right tire choice has a huge impact on ride quality and handling.

Ridetech utilized its on-site test track to develop high-performance front springs and optional front sway bar rates specifically for lowered suspension. Factory rear leaf springs are retained and work well in a lowered setup. A flip kit with adjustable hangars moves the axle above the leaf springs.

Ridetech’s shock absorber valving is best described as transformational. If you own one of these trucks, then you already know that the OE Ride quality is “okay”– especially if the shocks are older. With respect to ride quality, the Ridetech StreetGrip system excels.

While there are other “4/6 Drop” kits on the market, no other lowered suspension kit features Ridetech’s forged-aluminum-mono-tube-shocks with Fox Shock technology. They offer 24-position adjustable valving as well as Ridetech’s 1,000,001-mile warranty.

These shocks are custom-valved to settle rear wheel “bounce” that is typical for these trucks when not carrying a load. This keeps the rear wheels settled and in full contact with the pavement and will dramatically improve your driving experience – especially If your truck serves double duty as a family car – you’ll absolutely love these shocks.

The front half of Ridetech’s StreetGrip system consists of bolt-on coilovers with custom adapter brackets and drop spindles. Shocks are custom-valved to deliver luxury car ride quality and performance handling. Adjustable shocks let you fine-tune the shocks to your driving style.

Multi-position rear leaf spring hangers allow for up to 6.5″ of lowering. Heavy-duty steel components are made in the USA. Delrin frame-side bushings reduce deflection without stiction.
GMT900 Silverado-Sierra Flip Kit
The StreetGrip system features a heavy-duty, 100% bolt-on flip kit that relocates the axle above the leaf springs. By design, GMT900 trucks have enough frame clearance to eliminate the need for C-Notches.

Ridetech is driving the lowered pickup truck suspension to new heights of performance and value with bolt-on applications for every two-wheel-drive GM full-size pickup from 1963-2013 (plus S10/S15 trucks), the number of enthusiasts building and driving Ridetech Muscle Trucks is bigger than ever. Ridetech also makes it easier than ever to build a great looking truck with true high-performance DNA. 

With factory LS power, overdrive and tons of room for fat tires, the 07-13 Silverado/Sierra “GMT900” platform is the perfect starting point.  Just add a Ridetech StreetGrip lowered suspension system and head out on your favorite winding road.

    Lowered 2008 GMC Sierra short bed Reg cab truck Rear Squeaks can’t figure out where it’s coming from didn’t make noise until I lowered truck Do u have any thoughts about what going on

  2. Graham says:

    You may have to notch the truck bed just over the lowering shackle. The noise could be the bed and the shackle rubbing against each other. Test: Stand on the rear tire and push down on the bed as if it were in a turn or carrying some thing heavy. You should be able to reproduce the squeaking that you hear. That said, it is best to assemble most suspension parts using a suitable lubricant as well.
