Just as Klean63 and Madmoose have stated Church Boys are making their own arms that make a tremendous improvement to the stock front suspension. They are also compatible with the bolt on rack and pinion conversion as well.
The arms that are modified from CPP are called the "Church Arms" because they have a droop in them to accomodate the use of the bolt on rack kit. The standard cpp arms will not work down the road with the rack conversion.
Regardless of which brand you decide to go with you will need to ask yourself whether or not you plan to go to a Rack and pinion conversion. Currently you may not want to go that far with your suspension, but if you plan accordingly you will be set with the correct components at a later date.
