Understanding Camber 

Understanding Camber and Caster is critical to ensuring a properly configured alignment for your lifted Truck or SUV.  Camber and Caster are both detirmined by the relationship between your upper and lower balljoint.  Camber is the relationship between the upper and lower balljoint when looking at the vehicle head on, while Caster is the relationship of the two when looking at the vehicle from the side.  By using the adjustements afforded us by adjutable lower control arm bolts, or "Cam bolts" we are able to adjust our camber to help get our vehicle back into spec after modifying the suspension.  Below is a visual detailing how the adjustments can impact the location of your lower control arm.  The "Max Camber" on the visual below would cause your camber to be positive while the "Min Camber" setting would cause your camber to be negative.   The ideal camber setting is as close to 0 as possible 

Understanding Caster 

When it comes to lifted vehicles, camber bolts or "cam bolts" have more functions than merely getting a good alignment.  Cam bolts, when properly configured, can allow you to add positive caster to your alignment from the lower control arms.  This allows you to shift your tire forward in the wheel well to allow you to fit larger tires with less fender melting/trimming.  The same principle applies for our ADO Cam Bolt Lockout / Cam Bolt Delete Kit, which the visuals in this write up are modeled after.  When setting your alignment for a lifted vehicle, you ideally want to shoot for a caster number a bit higher than normal.  This helps tighten up your steering and can help improve ride quality after altering your suspension.  Leveraging your cam bolts to add caster will allow you to have a more mild caster setting on your upper control arms which in turn results in less tire rub.  Ideal caster numbers will vary slightly between vehicle platforms but at or above 3 degrees is a great place to be.  Properly configured LCA Cam Bolts can make the difference between rubbing and not rubbing when installing your larger tires.
