STAINLESS STEEL VALVES
YXZ1000R - POLARIS RZR1000

APE is a leading supplier of high performance and racing valves for powersports. APE stainless steel valves are precision manufactured from aircraft quality Inconel based stainless steel. This special material offers excellent resistance to heat and distortion. APE stainless steel valves are designed to be used in the most extreme racing applications including the use of exotic fuels, or will give many miles of trouble-free offroad use. They present an outstanding value. In most cases you can upgrade to APE stainless steel valves for less than the cost of replacement stock valves. All stainless steel valves feature hard chrome stems for extra long stem to guide life.

MANUAL CAM CHAIN TENSIONERS

APE manual cam chain tensioners are designed to replace the automatic and hydraulic tensioners on high performance engines. The automatic adjusters can back out when the throttle is closed suddenly at high rpm. This allows the cams to go momentarely out of time, and can result in bent valves and/or serious engine damage. Hydraulic tensioners have a tendency to put too much tension on the chain guide under high rpm/high oil pressure conditions, resulting in premature wear. Both problems can be eliminated with the installation of the APE manual tensioner.

APE Pro-Series tensioners come with mounting bolts and tensioner gasket.
