You'll run 35"–37" tires while maintaining corrected factory-like geometry — no drivetrain modifications needed.

What's included
- 4–6 Knuckles — Lifted to support your truck's new height and accommodate larger-diameter wheels without geometry compromise.
- M1 Loaded Strut Pair (Monotube, 6-inch) — Nitrogen-charged front struts engineered specifically for lifted applications, delivering smooth highway ride and off-road vibration dampening in one package.
- M1 Monotube Shock Pair — Rear shocks matched to the front struts for balanced suspension behavior across all terrain.
- 6-inch Lift Blocks and Crossmember Box — High-clearance design minimizes hang-ups on obstacles; fabricated construction offers longer lifespan than cast alternatives.
- Brackets, hardware, and skid plate — Everything needed for complete installation and protection.
Important notes
- Does NOT fit TRD Pro Series or XSP-X models.
- Requires 18-inch or larger wheels. Stock 18-inch wheels can be used but accommodate tires no wider than 11.5-inch; minor trimming may be needed to clear 35-inch tires.
- Cutting and drilling required during installation.
- Vehicles equipped with a two-piece driveshaft may experience take-off vibration, correctable with the Rough Country carrier bearing shim kit (SKU: 1776BOX1).
