What does it include?
  • All brackets, cross-members, steering knuckles, strut spacers, rear shocks, rear fabricated block and u-bolt kit, and hardware required specific to the 2014-2018/19 (Legacy) 2WD/4WD Chevrolet/GMC 1500 (Factory aluminum or stamped steel control arms only)

This is the Superlift 8” Suspension is the perfect solution for truck owners looking to run a 35” tire with a wider profile. This is a TRUE 8-inch Lift Kit for the Silverado and Sierra. It was designed and engineered to be an 8-inch lift from its conception unlike some companies that use their 6-inch lift components with a taller strut spacer to achieve 8 inches of lift. The steering knuckles and control arm crossmembers provide all the proper geometry correction for the true 8 inches of lift.

Using OE data files allows us to design lift kits that mimic the original factory designed components. This aids in installment and compatibility.  It also allows our engineers to design a kit that once installed not only retains your truck's excellent ride and handling characteristics but one that is also compatible with GM's Stabilitrac anti-skid system.

Nothing is left unattended with this 8” lift kit. The brake lines and front sway bar are relocated to make sure there is no binding through the cycle of the suspension.

The rear includes a set of fabricated lift blocks that locks in the axle ubolts though the blocks upper and lower plate giving you the strongest set of blocks on the market today. The block also has ubolts that capture the leaf pack to help counter axle wrap.

NOTE: Does NOT fit 2007-2016 Chevy Silverado’s and GMC Sierra’s with OE CAST Steel Control Arms

NOTE: This suspension kit WILL NOT WORK with any late model GM Truck or SUV equipped with MAGNERIDE from GM

Tire Wheel Backspacing Offset
35x12.5 20x9 4.5-5 -
35x12.5 20x10 4.5-5 -12 to -24

 The provided tire/wheel fitments are approximate. Actual dimensions of a given tire size can vary considerably from one brand to another. Manufacturers' wheel offset and backspacing measurement points are not always consistent. Backspacing greatly impacts tire-to-fender clearance when turning. Wheel width and backspacing influence whether the tires protrude past the fenders, and to what extent. Considering these important factors, we recommend that you fit-check your tire/wheel selection prior to purchasing.

  • Installation time: 8 hours
  • Difficulty level: 3 of 5

It is a well designed lift except for some of the powder coating flaking off on the thin sides of some of the brackets and we could not figure out how one bolt for the front differential skid plate goes in. Other than that it was a breeze to install! Looks great!

8" lift for my 2017 silverado 1500
Absolutely love this lift!!!!!! Truck looks amazing.


Superlift shocks are twin tube, velocity sensitive hydraulic shocks. Bilstein shocks are a mono-tube gas pressurized shock. The Superlift shocks are coated with a white paint; the Bilstein shocks are a brushed steel body with a nickel and clear zinc finish. Bilstein shocks are more tuned for the application and offer more precise valving.


From 2014-2016 Chevrolet Silverado and GMC Sierra 1500 Pickup trucks were available with three different equipped control arm set ups.  During this time frame, GM produce those trucks with 2 different knuckles – Aluminum and Steel.  Each style knuckle contain a different ball joint size. 

Superlift produces a kit for each set up for both 6.5 and 8 Inch Lift Kits.

2007-2013 – Cast Steel Control arms (K162)

2014-2016 – Cast Steel Control Arms (K160)

2014-2018 – Stamped Steel or Aluminum (K161)

Please refer to picture in order to identify which control arm your GM 1500 pick up has.
