The list of aftermarket modifications available for UTVs seems to get larger every year. With the addition of a suspension lift for our RZR came larger tires, too. Those upgrades (along with the weight of our ever-growing beer guts) put more stress on the stock rack and pinion steering system. After a few close calls on dirt fire trails from a heavy right foot and sloppy steering, we knew it was time for a beefier system. We soon found that Unisteer Performance Products' Rackzilla rack and pinion kit for the Polaris RZR had everything we were looking for in a quality, bolt-on replacement. We had Xtreme Unlimited in Oceano, California, complete the install, and in about 30 minutes. Granted, this is an accomplished shop with prior experience, but we think you might be able to do yours in under an hour.
