PISTON COMPLETE 11:1 C.R. T120TT
Complete 11:1 compression piston listed for the T120TT, as used in crankshaft and connecting rod assembly work.
CP202 is a complete piston listed for the T120TT, spec'd at 11:1 compression. The CP prefix marks it as a Hepolite-family piston, and "complete" in the parts book means it comes with rings and pin as a full assembly rather than just the bare piston.

This one turns up in the catalog under the crankshaft and connecting rods section, which is standard placement since piston selection ties directly to the rod and crank assembly it runs against. The 11:1 ratio is well above the standard road compression used on these engines, which tells you this was the high-compression option for the TT-spec engine rather than a general replacement piston.
Our record on this one is thin - it shows up once, tied to a single year. If you're rebuilding a T120TT motor or trying to match a high-compression setup, give us a call and we'll confirm this is the right piston for your bore and rod combination before you order.
