PATENTED DESIGN
| For decades, engine builders have been installing VSI inserts/adjusters on all valve jobs. Why? Because they are superior to plain shims. Only VSI has patented heat-retarding serrations. Whether you're a PER or CER (Custom Engine Rebuilder), VSI completes the valve job, building your repu- tation while doing a complete job for your customer. |
| High-Performance Series VSI® are the preferred valve spring insert when assembling High-Performance cylinder heads. Aluminum heads require the installation of inserts to prevent the valve spring from damaging the aluminum spring seat. Standard shims are unable to handle the stress of racing spring pressures. |
Patented Heat-Slashing Serrations.
