Crankshaft Tools

Crankshaft Tools: the rotating heart of your rebuild

The crankshaft is what turns the up-and-down of your pistons into the rotation that drives the car. It rides in the main bearings, carries the rods on its journals, and sets your stroke - which is a big part of how much displacement and torque an engine makes. When you build for boost or high rpm, the factory crank often becomes the weak link, and that's where the crankshaft tools and forged or billet crankshafts on this page come in. Swapping to a stronger crank means a full bottom-end teardown, so it's rebuild-time work, not a bolt-on.

What we stock

There are 25 products in this category right now, spread across 6 brands: Eagle (9), Manley Performance (8), Ford Racing (4), ATI (2), Wiseco (1) and Hot Rods (1). Current pricing runs from $22 to $2,107 - that's the live range for what's in stock, not a fixed promise. The upper end is billet and forged cranks like the Manley Subaru EJ20/EJ25 79mm Turbo Tuff crank and the Manley EVOX 94mm Turbo Tuff crank, while the Eagle Subaru EJ20/EJ25 billet crank sits just under them.

How to choose

Match the crank to your platform first, then to your power target. A billet piece like the Manley Turbo Tuff cranks is aimed at hard-use turbo builds; a forged unit such as the Ford Racing 5.2L Coyote forged crankshaft suits a big Mustang build, and the Eagle Chrysler HEMI forged 4340 crank gives you a specific stroke and reluctor for that engine. Stroke, rod-journal size and reluctor pattern all have to line up with your block and your tune. For powersports, the Hot Rods Polaris RZR 570 crankshaft is a direct replacement for that machine.

What else you need with it

A crank doesn't go back in alone. You'll want fresh bearings (628 in stock) to match your journal sizes, and if you're this deep it's the moment to look at pistons and your gasket kits and head gaskets for the reseal. Browse the full Engine Components section for the rest of the bottom-end hardware.

Fitment and ordering

Fitment data is listed on 4 of these products, covering sample makes including Mitsubishi, Ford, Honda and Polaris - with models such as the Mitsubishi Lancer, Ford Mustang, Honda CR125R and Polaris RZR 570 across roughly 1990 to 2017. Product names also cover Subaru and Chrysler applications. Confirm stroke, journal and reluctor details against your build before buying. Not sure what fits? Call our team at 813-535-5801 or reach us through contact us; the FAQ covers common questions. Every order ships free, and Affirm and Katapult financing is available on the bigger builds.
