Westcott Designs 3-Inch Front / 1.25-Inch Rear PreLoad Collar Lift Kit; Raw Aluminum (10-24 4Runner SR5, TRD Off-Road, Trail, Venture)Find parts that fit my vehicle

Level and Lift with Factory Comfort. This PreLoad Collar Lift Kit uses raw aluminum collars to raise the front suspension three inches and the rear one and a quarter inches, providing a level stance and extra ground clearance without altering the damping characteristics of the factory struts or shocks. By preloading the coil seat rather than compressing the spring, the design preserves factory ride quality and handling balance—ideal for daily driving and light off-road use. The 6061-T6 aluminum construction delivers exceptional strength and resists corrosion, ensuring the lift remains consistent over years of exposure to the elements.

Precision Fit, Convenient. Each collar is CNC-machined to exact OEM specifications for a slip-fit installation on the coil seat. The raw-finish aluminum can be left as-is for a utilitarian look or anodized to match your vehicle’s suspension components. No modifications to the struts or shocks are required, and stock hardware is reused for maximum simplicity.

Installation. Compress the coil spring using a spring compressor tool, remove the preload from the perch, slip the front three-inch and rear one and a quarter-inch collars onto their respective coil seats, then release the spring and verify proper seating before reassembling.

Application. The Westcott Designs 3-Inch Front / 1.25-Inch Rear PreLoad Collar Lift Kit; Raw Aluminum fits 2010–2024 Toyota 4Runner SR5, TRD Off-Road, Trail, and Venture models.
