The RLU-250 incorporates Holland Neway's 2-pin bushing design, which provides excellent roll stability and improved vehicle tracking and tire life. The end result is a reduced weight, heavy-duty air ride suspension rated for both 'on' and 'off' highway applications. The RLU-250-FMT is designed for lowboy (double drop) trailers and when combined with the RLU-250 suspension, provides optimum deck space and cargo capacity. Both suspension designs incorporate common air springs and shock absorbers providing excellent load equalization, as well as parts commonality.
