Hyfax Extender Wheel Spacer Kit-pro action

1       Unbolt the rear idler cross shaft with the two wheels from the suspension. Remove the C-clips and then the wheels from the shaft, the wheels are press fit onto the shaft, support bearing at race when pressing off wheels.

2       Install the wheels (snap ring side facing center) all the way onto the new shaft provided in the kit, allowing the C-clips to seat in the grooves. On SRX models only there’s a bracket to the inside of the rail that must be turned around and put on the outside of the rail by unbolting the rear pivot shaft, the end with the tab will now go to the rear, separate the two pieces with the smaller tab part to the inside of the rail. On RX-1 models the washer that is between the rail and shaft on each side is no longer used.

3       Put the idler shaft between the rails with the wheels in the lowered position (bottom edge of the shaft should sit on the extruded rail edge while lining up with the mounting holes of the rail). Place the locking brackets between the shaft and the rails with the bottom edge of the locking bracket sitting on the extruded edge of the slide rail, and the raised edges of the brackets lining up with the machined flats on the end of the shaft. Bolt the shaft in place using a drop of 271 (red) (or similar) loctite on each bolt and tighten.

4       Unbolt the 4 idler wheels to the front outside of the rails, the front bolts can be left in place. Discard the washer that goes between the wheels and the rail brackets, and the stock steel spacers in the center of the wheels. Put the new wheel spacers in the wheels to the large bearing spacer side. On the front wheels slide them over the stock bolts (the locking side of the spacer goes against the rail bracket), with the wheel in the lowered position. Put the original washer to the outside of the wheels, put a drop of red loctite on the bolt and then put on the nut and tighten. On the back set of outer idler wheels put the spacers in the wheels and put the locking side of the spacer against the rail bracket, with the original washer on the bolt slide the bolt through the spacer, bracket and rail. Put a drop of red loctite on the bolt then the nut and tighten.
