***Yes, these will fit onto 2005 and later SRW trucks with 8x170 bolt pattern, but unless you purchase the Ultimate Package that includes the custom made wheels, you will have these issues:
• Most dually wheels for 8 on 170mm are 16" diameter. The 2005 and later require 17" wheels or larger to clear the brakes.
• The adapters have 5/8" studs for additional strength and might not fit some aftermarket wheels
• These adaptors are designed to work with hub centric wheels.
• You can solve all of these issue by just going with the kit that include custom 17" wheels (part number SRWDRWUPF170)
