JE Pistons Wrist Pin Retainer - 0.630 In Diameter - 0.050 In Thickness - Wire Lock JE Pistons Wrist Pin Retainer - 0.630 In Diameter - 0.050 In Thickness - Wire Lock JE Pistons Most JE shelf pistons include double spiro locks as standard equipment. These locks are installed by spreading the lock between 1/8" and 1/4" and rotating the lock into the groove in the piston pin boss. Wire locks are installed in much the same manner but require chamfered wrist pins. Wire locks tend to spread side loads over more of the piston pin boss area and are considered to be a stronger method of holding the pin in place. Hook wire locks have a built in hook at the end gap. The purose for this style of wire lock is to prevent rotation within the lock groove itself. Tru arc locks fall between these two and can be used with the stock sharp edge wrist pins. The advantage of tru-arc locks is ease of installation and they can be re-used unlike spiro locks, however they are not recommended for medium to high horsepower applications.This Part Fits: Year Make Model Submodel 2007-2012 Honda CRF150R Base 2004-2015 Honda CRF250R Base 2004-2017 Honda CRF250X Base 2014-2015 Husqvarna FC250 Base 2004-2014 Kawasaki KX250F Base 2005-2015 KTM 250 SX-F Base 2007-2013 KTM 250 XC-F Base 2007-2013 KTM 250 XCF-W Base 2001-2013,2015-2017 Yamaha WR250F Base 2001-2018 Yamaha YZ250F Base 2015-2019 Yamaha YZ250FX Base
