This is a brand new complete throttle body assembly for the Polaris Ranger 800, Ranger Crew 800 and RZR 800 EFI and S. It is supplied as a finished unit rather than a bare casting - the TPS sensor and the IAC valve are both fitted and included, so there is nothing to transfer over from the old assembly and nothing extra to buy. That matters on these machines, because a throttle position sensor or idle air control valve that has been disturbed during a swap is a common source of poor idle and hesitation after the job is supposedly finished.
The assembly is a direct replacement for the original unit and the quality exceeds the OEM equipment it replaces. Every unit is tested before it is shipped. RMSTATOR note that all item pictures are accurate, so if you are unsure whether this is the correct assembly for your machine, compare the unit shown against your original part before ordering. As with any work on the fuel and electrical system, disconnect the battery before servicing - there is a risk of electric shock.

Frequently Asked Questions
Does this need any modification to fit?
No. It is a direct replacement for the original throttle body assembly, so it mounts and connects in the standard position with no modification.
Do I need to buy a TPS sensor or IAC valve separately?
No. Both the TPS sensor and the IAC valve are included with the assembly, so nothing has to be carried over from your old throttle body.
How do I know my original throttle body is at fault?
Erratic or hunting idle, hesitation off the throttle, a stuck or notchy throttle plate, and fault codes pointing at the throttle position sensor or idle air control circuit all point to the assembly. Compare the unit in the photographs to your original before ordering if you are unsure.
Is there anything I should do before fitting?
Disconnect the battery before servicing - there is a risk of electric shock while working on the assembly.
