- This model uses an eye on a twisted "Z" spring to locate the axle.
- The rear end of the spring curves inward towards the frame rail.
- Front and rear "Z" springs are different for all vehicles made through late 2014.
- Beginning in late 2014, some vehicles will use the same springs on both axles depending on the axle model. See remarks.
- This suspension was first used in 2008.
- This suspension is the same as the Peterbilt Low Air Leaf (2nd design).
- The bushing flange of RB-285 is towards the frame rail.
