Made to fit, made to order, made while you wait
Our story
C.H. Williams & Sons makes what other shops can't find. When a customer can't source the right length U-bolt anywhere else, locally or online, we make it ourselves, often while they wait.
We've built our name on straight answers and fair prices. If you don't need it, we won't sell it to you. Customers tell us they came in expecting a sales pitch and left with an honest quote, a perfect fit, and a lesson or two about their own truck.
From snapped J-bolts to full spring installations, we handle the jobs that require real know-how, the kind you only get from doing this work day in and day out.
