RZR, RZR-S, RZR-4 Adjustable PRV (oil pressure relief valve)

Holz Racing Products Adjustable Oil Pressure Relief Valve (PRV)
Replace your stock PRV bolt with one that is adjustable so that you can monitor and tune for optimum oil pressure.
We have found the stock oil pressure settings to be inconsistent between different RZR motors. Some motors with oil pressure that is too low will inevitably experience problems later on that may not have been detected or remedied without the use of an Adjustable Oil Pressure Relief Valve.
This part is a must for a remote oil cooler set-up. It is common with the addition of the longer oil lines and increased oil capacity for the engine oil pressure to drop.
Recommended for all motors especially ones with higher performance mods.

Includes:
- Adjustable PRV bolt
- Gauge w/ hose & fittings
- Detailed instructions for setting optimum oil pressure
