7.5 Inch Lift Kit | N3 Struts | Chevy/gmc Tahoe/yukon 2wd/4wd (2007-2014)

Built for Tahoe and Yukon owners who want maximum ground clearance and an aggressive lifted stance — this 7.5-inch lift kit delivers the height and geometry correction you need for 37–40 inch tires while preserving driveline angles. Featuring lifted knuckles, high-clearance crossmembers, and N3 struts, it's engineered to keep your truck handling predictably after the lift.

Installed and serviced at Road Runner Wheels & Tires. Most lift kits go in the same day. Call (678) 400-6467 to schedule.

What's included

• Lifted knuckles — precision-cast front knuckles that raise the spindle height and create the foundation for the lift geometry.
• Front and rear high-clearance crossmembers — 1/4 inch thick steel boxes, laser-cut for exact fitment, that replace OE crossmembers and provide unmatched ground clearance without differential or drivetrain modifications.
• Loaded N3 strut pair — matched struts with upper spacers to deliver ride height and damping tuned for the 7.5-inch lift.
• Lifted coil springs — rear springs engineered to support the added height and load while maintaining suspension geometry.
• Sway-bar drop brackets and differential drop brackets — critical geometry-correction pieces that keep suspension links and driveline components properly angled after lifting, preserving a factory-like ride quality.
• Shock extensions, brake-line brackets, and lower skid plate — complete hardware kit with Grade 8 fasteners to tie everything together and protect undercarriage components.

Important notes

• Does not fit Auto Ride or Auto Leveling models — confirm your Tahoe or Yukon does not have factory air suspension before ordering.
• Does not fit models with electric steering.
• AWD models require driveline conversion — the kit is designed for 2WD and 4WD (part-time transfer case). AWD Yukons must be converted to 4WD to use this kit.
• 18-inch or larger wheels are required — factory 17-inch wheels will not clear the lifted suspension.
• Minor cutting and drilling required — professional installation is strongly recommended.
• Refer to installation instructions for tire and wheel combinations — maximum tire diameter depends on wheel offset and backspacing; instructions detail proper pairings.
