COMP Cams POW351040 Sportsman Crankshaft Stroke Checker Engine Building Tool

The COMP Cams / Powerhouse POW351040 Sportsman Crankshaft Stroke Checker is a precision engine-building tool designed to accurately measure crankshaft stroke during engine assembly or inspection. This cost-effective alternative to traditional long-range dial indicator setups uses a standard 0–6" dial caliper (not included) to deliver accurate readings to within .001".

Key Features:

• Measures crankshaft stroke to .001" accuracy using a standard 0–6" dial caliper (not included)
• Mounts on the crankshaft main journals for a stable, repeatable measurement platform
• Measures rod journal travel from top to bottom of stroke for precise crankshaft stroke verification
• Compatible with assembled short blocks — zero the calipers on the piston at TDC, then measure down to BDC
• Works with any brand of dial calipers — no proprietary tooling required
• Professional-grade accuracy at a fraction of the cost of long-range dial indicator setups

This tool is an essential addition to any engine builder's toolbox, enabling accurate stroke verification on bare crankshafts as well as fully assembled short blocks. Simply set the gauge on the main journals, zero your calipers at the top of the rod journal, rotate the crank to the bottom of its stroke, and read your measurement — delivering shop-quality results without the expense of a dedicated long-range dial indicator system.
