Is there anyway to determine front sway bar size other than crawling under with a caliper and measureing it.

 

If you had the build sheet for the truck it would be listed on it. But even then, the only way to be 100% positive is to get under there and measure it.

 

Thanks for the reply. I just went and bought a caliper. I tried measuring it with a tape measure it converted out somewhere between a 33 and a 35 so now I will be more precise.

 

For those without a caliper, use an adjustable wrench and snug it down on the bar. When you pull the wrench away, it becomes much easier to measure between the two flats of the wrench instead of trying to measure across a round bar.
