As of 1/30/22 I only have the highboy version ready for sale, the others are coming soon. Currently there is a 1 week lead time on the highboy kit


This is a 4 link kit to install a 2005+ Super Duty front axle under your 1967 to 1979 F series pickup. It consists of a frame mouned bracket, 3/8" wall 1.75" OD DOM tubes, Rock Krawler brand rod ends, and hardware. This is an extremely heavy duty and well made kit. The upper tubes are formed into an "S" shape to wrap around the outside of the frame, and the lower tubes sit just below the frame to give excellent ground clearance.

There will be many variations of this 4 link kit, and I will list different models for sale soon. The F26A version (1967-1977 highboys) is ready now with about 1 week lead time. There will be three F250 2wd versions, at least five F350 2wd versions, and eventually every other model for the 1979 and older trucks. Whatever your frame type was when you orderd a front end kit, you will want to select that same frame type. When in doubt, email me a couple pictures of your frame rail about 16" behind your front cab mount and I can help you figure out which frame option to select.


For each model, I will have two lengths of tube options. A shorter set of tubes (pictured on the red truck) for most oem springs, whether that's with my tall or standard buckets, and then a version that's slightly longer and accommodates some larger lifts.


These tubes are machined on either end- the rod link end has 1.25" threads, NOT welded on threaded ends, then the other end has the outside diameter cut down for the last .25" so that the "C" shape pieces perfectly locate and sit over the tubes. The tubes and "C" pieces get welded together, then a cone shape steel piece slides over top and is welded to the tube and "C" piece, greatly adding to it's strength. The tubes are 3/8" wall and this assembly weighs more than the radius arms. The rod ends are Rock Kralwer part numbers RK04821 and RK05068. These are well made greasable rod ends. While they should last a lifetime, they are fully serviceable and in a worst case scenario replaceable.


Please know that 4 link takes more time and is a little more tricky to set up than a standard radius arm. It is very doable and you don't need any special tools (well besides a 27mm socket and wrench). Where radius arm brackets and a radius arm can be installed in about 2 hours, this takes at least double that and perhaps longer in some circumstances.


As always these are designed, sourced, laser cut, formed, machined, welded, and powdercoated in the US!
