Product Description
SU HS4 1½" Throttle Disc Kit with Screws & Gaskets – WZX1323K
Complete genuine SU throttle disc kit for 1½" SU carburettors, ideal for replacing worn or damaged throttle components during carburettor repair or refurbishment.
The throttle disc, also commonly known as the butterfly, controls airflow through the carburettor as the throttle is opened and closed. Wear around the disc, spindle or fixing points can contribute to poor throttle operation and unwanted air leakage.
This kit provides the throttle disc together with the associated fixing screws and gaskets for a more complete installation.
Kit includes:
- 1 × 1½" throttle disc / butterfly
- 2 × throttle disc fixing screws
- Carburettor flange gasket
- Air cleaner gasket
Suitable for:
SU H4, HS4 and HV4 1½" carburettors where WZX1323 is specified.
Used across a variety of classic British vehicles fitted with 1½" SU carburettors.
Part Number: WZX1323K
Brand: Genuine SU
Size: 1½"
A convenient complete kit for servicing the throttle disc assembly without having to source the individual screws and gaskets separately.
Please check your existing carburettor type and part number before ordering to confirm suitability.
