This is our bolt on 3 link kit with a three piece cross member. The center section is adjustable height for transfer case drop from 1/2″ down to 1-1/2″ but also for those who already have a Slip Yoke Eliminator and want to do a 1/2″ tuck, simply zip off the upper mounting holes of the cross member and bolt it in. In addition we added some adjustability to allow you to do up to a 2″ stretch up front. We designed this with the adjustability to use with or without frame stiffeners. Lower Links are made from 2″x.25″ 1026 DOM with 1.25″ Chromoly heat treated heims. Upper Link is 1.5″x.25″ 1026 DOM with 7/8″ Chromoly Heat treated heim joint. The cross member is made completely from 1/4″ plate. Installation only requires drilling some holes, or you can weld the link mounts on.
