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 installa- tion 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.
