Key details

- PACALOY spring construction with titanium retainers.
- KVS58-BT kit; not the higher-load BTX version.
Fitment

Installation
The engine builder must measure installed height, spring pressure and coil-bind clearance against the selected camshaft. Follow Kelford’s fitting data; an engine code alone does not determine final assembly clearances.
