This Adjustable Linkage Kit is designed as a direct replacement for Haldex 48100225 and equivalent SRK168-style height control valve linkages used on heavy-duty truck and trailer air suspension systems.​


The kit features a steel, round, adjustable rod that can be cut to length within its approximately 13.5" to 19.5" usable range, allowing it to fit a wide variety of axle and suspension layouts while maintaining proper ride height.​


When installed between the suspension bracket and height control valve, this linkage transmits suspension position accurately, helping maintain consistent ride height and protecting air springs and related components from over-extension or over-compression.
