ReadyLift offers model specific wheel spacers designed for 07-18 Chevy Silverado and GMC Sierra 1500 6-lug trucks and SUVs with the ReadyLIFT 4" SST Lift Kit. These 1/2" quality spacers are precision CNC-machined from 6061-T6 billet aluminum for maximum strength and longevity and are HUB Centric. The ReadyLift 15-3485 wheel spacers are designed for use with the ReadyLIFT 69-3485, 69-3285, 69-3495 and 69-3295 4" SST Lift Kit when running the factory wheels and tires. Wheel spacers are required when using the factory GM wheels and the 4" kit to properly space the factory wheel away from the suspension. If you intend on using the factory wheels and tires with your 4" Lift Kit, these wheel spacers are required to be used in order to maintain the product warranty of the lift kit. Works with both factory aluminum and steel wheels. Each wheel spacer is both hub centric and wheel centric to ensure the absolute perfect fit with your hub and wheel. You will not find a stronger wheel spacer in this size anywhere on the market. When installed the 15-3485 wheel spacer will place the outer wheel lip in line with the fender. The wheels WILL NOT stick out using this spacer. Can be used on '99-07 GM 1500 trucks or any GM truck with a 6-5.5 bolt pattern up to 2018 to resolve wheel or tire fitment issues or just to increase track width. Not for use on 2019 GM 1500. Sold as Pairs. (two wheel spacers) Quantity 2 = one pair. Made In The USA.

Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.

Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.
