Extended / Long Nose Crank Collar
For Improved Oil Pump Engagement
Kenjutsu Racing Lab
Nissan specialists Conceptua Tuning can offer these superb quality Crank Collars. These are commonly used to help prevent the common problem of oil pump failures on engines with short nose cranks. If the engine is tuned, revved harder than standard or often hits the limiter, the long nose crank conversion is an essential upgrade!
