Wiseco Tracker 10.5:1 +.010 Piston Kit - Harley Evolution 88ci

The Wiseco Tracker 10.5:1 +.010 piston kit is a forged piston set for 88 cubic inch V-twin engines, offering a 10.5:1 compression ratio and a +.010 inch oversized bore. Forged piston crowns give these pistons strength, and the generous valve pockets are designed to accommodate bigger valves for riders building an engine for more performance. Riders choose this kit for the higher compression it provides, which is aimed at improving throttle response and power. Each piston carries an ArmorGlide skirt coating that reduces friction and improves scuff resistance. Force-fed pin oiling delivers added lubrication to the piston pin, supporting durability under demanding operation. The kit is specified for a 4.000-inch stroke and is well suited to a rebuild where the cylinder walls are being cleaned up with the oversized bore. Proper cylinder boring and honing are required, and a dyno tune is recommended to make full use of the increased compression.

For off-road / closed-course race use only.
