  • PARALLEL 4-LINK WITH PAN-HARD BAR (1.50" BARS)

In many applications, such as late model trucks, this configuration avoids interference between the upper bars and the OEM gas tank. The parallel 4 link is also slightly easier for the casual installer to visualize and install because there are fewer bar mounts to deal with... the frame brackets and axle brackets carry both upper and lower bars. (TIG weld)
