Pro Series XP Racing Valve Spring Kit
Skunk2 is proud to introduce its Pro Series XP
(Extra Pressure) Racing Valve Spring Kits for Hondas B-series
VTEC and K-series i-VTEC engines. Each
kit includes Skunk2s high-quality race-proven dual valve springs
that are the result of nearly two decades of racing and engine
building experience.
XP features a higher seat pressure for turbocharged and extreme
high RPM motors. This spring has a seat pressure of
100lbs at 1.600 for the K-Series and 93lbs at 1.320 for the
B-Series engines while keeping the coil bind height for higher lift
camshafts.
Each Pro Series XP Racing Valve Spring is
manufactured exclusively from super-clean, chrome-silicone wire
milled in Japan. By using inner and outer springs mated together
through a slight interference fit and with differing frequencies,
Pro Series XP Racing Valve Springs are able to prevent
valve float and maintain valvetrain stability at engine speeds in
excess of 11,000 rpm. Wound by a premier North American winder, our
Pro Series XP Racing Valve Springs retains its
durability and strength that results in improvement to the extreme
fatigue limit of the wire and enhanced resistance to load loss.
Pro Series XP Racing Valve Springs are engineered
to handle the demands of extreme-lift camshafts operating at
prolonged, high-rpm use at championship-level racing. Skunk2s Pro
Series XP Racing Valve Springs for Hondas B-series
VTEC and K-series i-VTEC engines are
simply the best on the market. Pro Series XP Racing
Valve Springs have been tested at speeds exceeding 11,000 rpm on
our engine dyno, street, and the race track. Our superior,
Japanese-milled, super-clean chrome silicone wire is 100-percent
eddy-current inspected prior to coiling. Next, they are
heat-treated, shot-peened, and chemically polished for strength and
durability. A special nitriding process concludes Skunk2s rigorous
manufacturing process. The end result is a lightweight valve spring
that safely accommodates high-lift camshafts and features superior
resistance to load loss, even under extreme operating
conditions.
Skunk2 designs, develops, and tests its entire valvetrain lineup
in-house to ensure superior quality and maximum performance gains.
During development, each valvetrain component is tested both on the
dyno and the road, including 11,000 rpm drag racing engines and
17,000 rpm superbikes. Manufactured from the best materials
available, Skunk2 valvetrain components provide exceptional
performance, reliability, and quality. These components remain
standard-issue on each Skunk2 vehicle that we build and
support.
