Re: Ordered from Western Chassis - received Chassis Tech?
15x7 truck rallys have a 3-5/8" bs.
No issue.
15x6.5 and 15x8 truck rallys have a 4" bs and may require trimming of the lower a-arms around the ball joint.
This is a known issue.
A lot of aftermarket rally wheels only have a 3-1/2" backspace.
You have to compare apples to apples when you are talking wheels and spindles working together.
