ReadyLift 2.25" Front Leveling Kit with Control Arms for GM 1500 (2017–2018, 6-Lug)

• Premium 2.25" front leveling system that combines a CNC-machined billet aluminum leveling spacer with DOM-tube steel upper control arms for a strong, durable, and precise lift.
• Replaces the factory stamped steel upper control arms with heavy-duty ball joints and maintenance-free anti-resistance bushings, mitigating the risk of stamped steel arm failure in lifted GM 1500 applications.
• Explicitly designed for 2017–2018 GM 1500 trucks with stamped steel or aluminum control arms (not cast steel); includes side biter washers for precise alignment and long-term stability.
• Maintains a smooth, factory-like ride while enabling up to 33x11.50" tires; some wheels may require a 1/2" front spacer (part 15-3485) depending on wheel and backspacing.
• Clear installation guidance: measure hub center to fender bottom edge at 12 o’clock with wheels straight to confirm fitment; install without the lower horseshoe spacer to achieve correct front lift height and suspension geometry.
• Compatible with 6-lug GM 1500 platforms; some configurations may need front wheel spacers or adjustments for tire/wheel combos on factory wheels (up to 285+ tires may require spacer in front).
• Includes CNC-machined billet aluminum leveling components, DOM steel upper arms, heavy-duty ball joints, maintenance-free bushings, and side-biter washers; product dimensions 16 x 12 x 6 in, weight 25 lbs.
