It is the same thing. This is a good kit, but the most expensive option on the market. They(and most companies) use a stock RHD drag link and a axle side raised trackbar bracket. It's really all you need. I would go with the cheapest priced kit that offers this setup you can get. EVO has this same kit and is competitively priced.
Synergy is mentioned above, but they replace the stock RHD drag link with their HD draglink and it costs more. I am not interested in paying more for a beefed up drag link that doesn't take any abuse that a stock one cant handle.
If you already have a axle side raised trackbar bracket, find one used, or decide to al la carte your kit and make it yourself, then crown makes a RHD draglink for cheap and is the option I went with
If you do go with the crown option, you will either need to buy the taper bit to drill out the knuckle(pain in the ass in my opinion and costs more for the bit) OR you will need a sleeve for the draglink and synergy sells them.
