Chevrolet Corvette C5 - LS1 and LS6

Texas Speed & Performance is proud to offer the latest version of the best dual valve spring kit on the market!  This kit now includes our patent-pending Precision Race Components integrated seat and seal.  You no longer have to worry about special installation tools for your valve seals, tearing a valve seal upon installation, or valve seals popping off!  Our new integrated seat and seal will work with factory-size valve guides and CANNOT be used on any aftermarket bronze guide applications!

The polished TSP .660" spring kit featuring PAC valve springs is the newest offering in valve spring technology offering the latest processes and material for maximum spring life.  PAC Racing is a leader in valve spring technology, so it was only natural to team up with the best in the valve spring industry for our latest offering in a valve spring kit!  We have developed a .660" dual spring kit with the help of PAC Racing that still offers excellent valvetrain control, even for the more aggressive hydraulic roller camshafts.  These valve springs will offer excellent durability and stability and will work well with factory-style lifters.  PAC polishes the valve springs, which helps to increase the overall life of the springs.  This greatly reduces the chances of spring fatigue and failure.  PAC's polishing process is completed without losing any pressure in the valve springs, so you maintain all of the capabilities of the non-polished version.

• American-Made PAC Racing Polished Dual Valve Springs Rated to .660" Lift
• Patent-Pending Precision Race Components Integrated Seat/Seal for Dual Valve Springs
• Titanium Retainers

The 228/232 camshafts use lobes that are designed to be both beehive & double valve spring friendly.

The 228/232 camshaft is available in a wide variety of lobe separations. The most popular options customers select is either the 112 LSA or the wider 114 LSA.  The 112 LSA helps to bring the camshafts powerband lower in the rpm band.  The lower LSA also creates a slightly rougher idle.

 

The 228/232 camshaft is a very popular camshaft for customers wanting a very streetable camshaft that makes approximately 5-7 more horsepower than the 228R camshaft.  Dyno testing has shown the 228/232 camshaft to make a solid 50-55 RWHP gains with all other supporting bolt-on modifications in place.  The 228/232 camshaft is large enough that we recommend a minimum 2,800 RPM stall converter in automatic cars.  Tuning will also be required in both automatic & manual applications.

The 224/228 camshafts use lobes that are designed to be both beehive & double valve spring friendly.

The 224/228 camshaft is available in a wide variety of lobe separations. The most popular options customers select is either the 112LSA or the wider 114LSA.

The 224/228 camshaft is a popular option for guys wanting more exhaust duration in combination with the 224 intake lobe. This camshaft is very popular for guys running very streetable boost engines. It has awesome drivability while making a solid 40+ rear wheel horsepower gains in N/A applications & even more in boost applications!
