I like to keep it simple...let the manufacturer do all the testing and all I need to do is bolt them on. On Rhinos, back in the day, Bilstein and W.E. Did a great job at this for the everyday riders. Now days it seems Fox and W.E. Are the go to brands. Other manufacturers make great shocks, but you may need to do your own testing and adjustments to dial them in. I went with the Fox RC2 2.0s on my last RZR and they were awesome out of the box. I understand for best performance every shock needs dialed to a specific car, weight, driver, driving style. That said I think You can't go wrong with Fox, King, W.E., etc....for quality...but for ease of setup I think W.E. and Fox have made it easy. To get you close to perfect in a bolt shock that may need a click here or there and a little preload adjustment.
