New Sidewinder roll over valve kits
1 Attachment(s)
I have been receiving quite a few requests to build a ROV kit for the Sidewinder. With that in mind, we have designed a ROV kit for the Sidewinder that replaces the normally closed OEM check valve with a normally open system similar to our Viper ROV kits.
Just like our Viper ROV kit, the Sidewinder ROV kit is a premium unit that features a Roll Over Valve Control Module (ROVCM) and the quick prime oil pump re-prime system!

I didn't think the Sidewinder needed a roll over kit..?

The stock normally closed valve does work. However some of my customers were having trouble with the stock OEM unit freezing closed. Usually it happens when the sled sits outside overnight in below freezing weather. If it freezes closed and you start the engine, it can over pressurize the oil tank causing it to leak at oil tank halve seal. To repair the leak requires disassembling the oil tank and re-sealing it.

Our ROV kit uses a normally open valve which is in the venting position while the sled sits overnight. Because the valve is already open and doesn't have to change positions during a cold start, the breather system can start venting right away. This allows the warm air to flow from the oil tank un-restricted as soon as possible. Which in turn, thaws out any accumulated moisture in the breather line that may have froze.

Basically our system is a normally open option for Sidewinder owners who may be having a freezing closed concerns with the stock normally closed ROV!
