Several mountain riders have discovered, clearly not by intent, that some of the front end components on their new REV-based mountain sleds are not as stout as the previous ZX-based chassis. This is when theyâ€™re hitting things like stumps and rocks; severe impact situations that wreck things like the â€œflying nunâ€ (wing-shaped front cross-member at the bottom of the chassis that the lower a-arm brackets attach to).
In response, Ski-Doo has been working on stronger parts in this area. If the frame is not too severely damaged, it is be possible to rebuild the front end of the frame without compromising its strength. There are now several â€œoptional reinforcementâ€ parts for the very aggressive rider, or for race use, or anyone riding in off trail conditions (i.e.; not enough snow to cover hidden obstacles) where this sort of carnage occurs (you know who you are!)
Now offered is a front plate reinforcement (#518 324 107), a â€œstiffenerâ€ (# 518 324 096) and a corner reinforcement (#518 324 181). Also available are grade 10.9 lower a-arm bolts (#207 607 046) that must be inverted from their original position. The belly pan must also be slightly modified with the front plate reinforcement installed.
