Avoid full head removal during valve work – thanks to in situ removal and replacement capability
Toolset allows access to valve springs and guides while the cylinder head remains in place, using compression and release tooling to permit removal and installation of springs and bushings. The approach reduces the number of disassembly steps required for upper engine service.
Servicing becomes faster and less labour intensive, as access is maintained without removing the head. That reduces workshop time on routine valve jobs.
Work across common engine types – with compatibility for 8, 16 and 24 valve engines
Design supports the listed valve configurations so a single set covers multiple cylinder head layouts. Compatibility avoids the need to buy separate specialised tools for each valve count.
Suitable for garages that handle a variety of vehicles, allowing one toolkit to cover several common engine types. Handy for mixed workloads and small repair shops.
Stay organised on the move – with the supplied carry-case
Components stow in the included carry-case for compact storage and easy transport between jobs. A dedicated case reduces the risk of losing small parts and keeps tools protected.
Keeps parts organised and ready for on-site repairs or shared workshop use. Portable storage helps maintain order and speeds setup time.
