4 Inch Lift Kit | Toyota Tundra 2wd/4wd (2016-2021)

Built for Tundra owners who demand ground clearance and aggressive styling without sacrificing factory-like handling, this 4-inch lift kit transforms your truck while preserving driveline geometry. Rough Country's precision-engineered design lifts the front to level with the rear, letting you run 33–35 inch tires and tackle obstacles that stock trucks can't clear.

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

• 4-6 Knuckles — Lifted front knuckles that raise the front axle while maintaining proper caster and suspension geometry.
• N3 Shock Pair — Nitrogen-charged shocks engineered for the balance between highway ride quality and off-road vibration dampening.
• 4-inch Lift Kit Box — Precision laser-cut suspension components and brackets fabricated using computer-aided design for durability and fit.
• Strut Spacer Box — Spacers that level the front with the rear and maintain factory suspension angles.
• High-Clearance Crossmember — Heavy-duty front crossmember designed to clear off-road obstacles without hang-ups; no modification to the stock differential required.

Important notes

• Requires 18-inch or larger wheels; stock 18-inch wheels can be used but limit tires to 11.5-inch width maximum.
• In some cases minor trimming may be needed to clear 35-inch tires — verify your wheel/tire combo with our team before purchase.
• Does NOT fit Pro Series or XSP-X models.
• On vehicles equipped with a two-piece driveshaft, take-off vibration may occur; this is corrected with the SKU: 1776BOX1 carrier bearing shim kit (sold separately).
• Cutting and drilling required during installation.
