Except for the air shock they will all be replaced with HPG plus so they are at least serviceable. Does it matter if the nitrogen charge port at the top of the shock is pointed outside from the sled or pointed inside towards the sled. Items marked "Final Sale" are not eligible for return. Right from the factory this sled had a saggy rear end so I recharged the rear shock to 300 psi & after that it was much better. Our Get the best deals for Ski Doo Hpg Shocks at eBay.
