Polaris RZR Billet Front Sprague Carrier Roller Cage

JJ and A Racing's "ROCK SLAMMER" Front Differential Sprague Carrier Roller Cage 

In November 2007, after already breaking many OEM Plastic 3-Piece Front Roller Cages in our shop's 2008 RZR, we had finally had enough!

This is our own unique design (manufactured and sold by us) with all of the weak areas of the Polaris/Hilliard unit addressed.

We CNC machine our billet 1-piece roller cage from 7075-T6 aluminum and then we hard-coat it.

This is not color-anodized... it is an industrial hard-coating process.

It is absolutely not possible to build a higher quality aluminum unit!!
