All About Ride Height in Leaf & Coil Spring Vehicles

All About Ride Height

Just because the manufacturer of your ride had their ideas about how she should sit does not mean you have to agree with them. How she sits, whether the factory look, or a stance more to your liking, is for you to decide. What About The Factory Stance? Because our early 20th century roads were […]

Why Lowering and Lifting Blocks Can Cause Axle Wind-Up

We all know the quickest and cheapest way to change the ride height of a leaf spring equipped vehicle is by using blocks between the axle and a spring. Heck, it can’t get any simpler. Remove the U-bolt, slip a block in, bolt her back up, and, wa-la, a new stance. But there’s a price […]

Why Unfinished Vehicles Tend To Sit Too High

Springs support weight, so if you measure the ride height of an unfinished vehicle, you won’t be measuring the final stance. You’ve just installed your new springs on your unfinished vehicle, and it sits too high. Keywords there were unfinished vehicle. Remember, springs support weight and all those things that have not been installed on […]

Is There A Trade Off Between Comfort and Handling? (Also, Diagnosing a Leaning Bonneville)

Q – I’m interested in new springs for my 64 Bonneville. I bought new springs from XYZ Company 2 years ago and I’m not happy with the results. When I was having them installed the mechanic said one of the rear springs was bad so I got a replacement. I wanted a pair, but they […]
