ProAmPrerunner UprightsProduct images may differ from actual product appearance.
The Prerunner uprights provide for an “off-the-shelf” kit with standardized dimensions. This allows fabricators to cheaply and easily manufacture replacements and help reproduce suspension designs, while still providing a design that can be used with a large variety of different hub assemblies and brake calipers. These Prerunner uprights use a 5.4” billet chromoly clevis and 2” bolt on snouts which can be used for vehicles up to 3500 lbs. with 35” tall tires.
Prerunner uprights are available in 10°, 12° and 14° inclinations and in 9-1/4", 10-1/2" and 11-1/2" kingpin lengths. These are perfect for Class 10 cars, large prerunners and buggies with a-arm suspensions. The kit does not include bolts, nuts, spacers or uniballs.
