HOT RODS STROKER CRANKSHAFTS
Long Stroker Crankshaft
In addition to Hot Rods heavy duty OEM replacement crankshafts, Hot
Rods also offers a full line of drop-in stroker crankshafts. Not only do these
stroker cranks bring about a heightened level of performance and increased
displacement, but do so without costly case machining, custom cam chains or
spacer plates. Better yet, many Hot Rods stroker cranks even utilize the engine's
stock piston.
Additional Hot Rods stroker crankshaft features:
• All stroker crankshafts are sold complete and ready for installation with the
original proven Hot Rods connecting rods, top end bearings and crankshaft
webs • Factory assembled and trued
