The Lone Star Racing DC-PRO and DC-6 outer linkage is made from laser cut machined 4130 tubing and plate, and the Inner linkage is made from billet aluminum. It comes with the bearings and seals already installed; all you need to do is re-use the OEM inner pivot tubes, dust caps and bolts.
Some advantages to the DC-PRO and DC-6 linkage over the others, is that its lighter than stock. You can remove the shock and lower bolt without having to pull apart the linkage, and the rebound adjustment screw is still accessible at ride height. It has fully greasable pivots at all locations, and it is designed to reduce the bucking normally associated with the stock linkage.
DC-PRO Linkage needs to use an aftermarket shock (best set up)
DC-6 linkage will use a stock shock (just needs a different spring)
