FMVSS No.126 compliant

The NHTSA's Federal Motor Vehicle Safety Standard (FMVSS) No.126 requires all new passenger vehicles to include Electronic Stability Control (ESC) systems that meet certain standards that can be tested through a comprehensive series of evasive maneuvers. Aftermarket products must meet these standards as well.

Zone Offroad Products is leading the industry by independently testing all suspension kits to verify the kits are fully compliant with the stability control system requirements set by Federal Motor Vehicle Safety Standard (FMVSS) No. 126.

  • Differential skid plate and support strut included for added protection when hitting the trails
  • Multi-point differential mounting system corrects drive line angles for proper geometry

FMVSS No.126 (ESC system test) Compliant - With the popularity of Zone's 4.5" lift kit for the 2007-2013 GM trucks, the engineers at Zone Offroad Products have designed the new 2014-16 kits to retain many of the great features customers have comes to expect with fitment for the new electronic power steering on the 2014-16 trucks.

The system includes a pair of fully boxed heavy duty crossmembers and robust ductile iron steering knuckles engineered to work with the redesigned steering. A 3-piece differential relocation system is utilized to correct front pinion angle with the center differential brace tying front and rear crossmembers together for a sturdy differential mount. This coupled with the differential skid plate and crossmember brace create an incredibly strong front subframe designed to correct suspension geometry while increasing ground clearance.

To retain factory ride quality a pair of bolt-on 4.5" strut spacers are used to provide lift. These install easily without the need to disassemble the factory strut. Also included in the kit are a pair of CV spacers, brake line brackets, sway bar relocation, and all the necessary hardware to complete the install.

To lift the rear and level the stance a 4" tapered block is utilized along with longer u-bolts, brake line bracket and your choice of hydro or nitro shocks.

New for 2014-16 is the availability of both forged steel and forged aluminum knuckles from the factory. Zone Offroad Products offers kits to fit both steel and aluminum knuckle equipped trucks. Check your vehicle before ordering to ensure the correct kit is shipped. Accessories for this lift kit include Zone front skid plate available separately.

As with all Zone Offroad Products, this 4.5" lift kit for the new 2014-16 Chevy/GMC 1500 trucks is backed by a limited lifetime warranty.

Important Notes!

  • You must verify if your vehicle is equipped with Steel or Aluminum steering knuckles from the factory prior to placing your order
  • All wheel drive models require drive line modification
  • Frame bracket modification and minor welding required
  • To reduce trimming required with 20" wheels, 5.75" backspacing recommended
  • Will not fit models equipped with magnetic ride control.
  • Factory 17" and 18" wheels cannot be reinstalled due to tie rod end interference
