Fitment

• 2020-2025 Chevy Silverado / GMC Sierra 2500HD/3500HD, including dual rear wheel trucks
• Does not work with AT4X or ZR2 models
• When setting the torsion key adjustment bolt, do not exceed 27" from wheel center to fender edge; over-lifting tops out the suspension, hurting ride quality and wearing components

Tire fitment

• 35x12.50 with no trimming on a 20x9 wheel with 0 offset
• Max with trimming: 35x12.50 on a 20x10 wheel with -18 offset
• Silverado and Sierra fender openings differ; minor trimming may be needed depending on true tire size and design
• Max tire width on stock wheels: 11.5"
• ReadyLIFT bases its wheel and tire recommendations on specific wheel and tire brands, and sizes vary by manufacturer, so test-fit every wheel and tire combination before installation.

Install notes

• Estimated installation time: 5.5 hours +/- 1 hour (excludes alignment and wheel/tire assembly).
• Read the instructions completely before starting. ReadyLIFT recommends installation by a certified mechanic.
