Built utilizing the same processes used in Xceldynes® Formula 1, NASCAR, and various other endurance-based applications that demand exact tolerances and maximum durability
Using the absolute finest titanium alloys available
High flow design increases flow characteristics and horsepower
PVD coated for outstanding wear resistance
40-percent lighter than comparable steel valves, which increase valve spring life
Used in conjunction with our alloy valve seats gives the longest-lasting titanium valve/seat combination available today
XCELDYNE® VALVE SEATS
An absolute must to replace factory seats that are prone to causing wear issues and premature valve failures
Heat dissipation (thermal conductivity) increased 5-7 times faster leading to extended valve life where valve contacts seat known as "seat erosion"
Requires minimal machining
Precision CNC machined for dimensional accuracy, flatness and roundness
Typical interference fit of .004-.005
XCELDYNE® RETAINERS (TITANIUM AND HIGH-TECH STEEL)
Lightweight CNC machined titanium retainers greatly reduce valvetrain mass and increase engine RPM
Increases valve spring life over heavier, stock steel retainers
When used with Xceldynes® machined valve locks, you have a perfect retainer/lock/stem fit for unprecedented high-RPM valvetrain control
XCELDYNE® VALVE GUIDES
Built from Xceldyne's specified blend of Maganeze-bronze
Heat dissipation (thermal conductivity) and valve stem lubrication increased substantially leading to extended valve stem life
The highest tolerances for correct valve stem support and fitment in cylinder head
XCELDYNE® STEEL SPRING SEATS
Precision CNC machined from 8620 case hardened steel
High tolerances ensure seats are flat for longest possible life
Pad is parallel to bottom surface for consistent spring pressures
Specially designed for CV4's valve springs, and available in varying thickness
XCELDYNE® SPRING BUCKETS
Built using the same technology as our Formula 1 buckets out proprietary steel for the lightest and strongest part possible
Diamond-like-Carbon (DLC) coating substantially reduces the buckets coefficient of friction, and decreases valvetrain wear temperatures
Increase RPM potential which increases horsepower
Tighter tolerances for less "rock" in the cylinder head, increasing cylinder head life
A must for high lift camshafts
XCELDYNE® VALVE SPRINGS
Made from the highest quality Kobe spring wire
Designed for use with most cam grinds
Single spring, low-drag design
None of the "crutched" two-spring designs that add to your valvetrain mass which in turn costs you horsepower
XCELDYNE® VALVE LOCKS
CNC machined from 8620 steel for a perfect fit and correct spring height every time
An industry first purpose-built intake-sized and exhaust sized design based on valve stem sizes that are sized different
Color coded for ease of fitment, blue for intake, and red for exhaust
Designed to stay locked at high RPM where stock stamped-steel locks suffer
