Hot Rods

Does the bottom end of your dirt bike, ATV or UTV need rebuilding or strengthening? Hot Rods makes crankshafts, connecting rods and bottom-end parts for off-road motorcycles and powersports. Here you'll find complete crankshaft assemblies, connecting rod kits and parts for a thorough engine rebuild.

Crankshafts for MX, ATV and UTV

Hot Rods is an American brand focused on the engine bottom end in off-road motorcycles, ATVs and UTVs. The crankshaft and connecting rod are among the most heavily loaded parts of an engine, especially in machines ridden hard on trails or the track. Hot Rods therefore offers both replacements for factory parts and stronger versions for engines with more power or a bigger cylinder. The range covers many popular models with both two-stroke and four-stroke engines.

Hot Rods' key products

Complete crankshaft assemblies are the core of the range and come assembled, ready to install. Connecting rod kits with bearings and crank pins are used when rebuilding a crankshaft. For bigger engine builds there are stroker and heavy duty versions that add stroke or handle more load. Hot Rods also offers bottom-end kits with bearings and gaskets, along with other engine parts. See each product for exact model and year.

Frequently asked questions

When should the crankshaft be replaced on a dirt bike?

It depends on engine type, use and service intervals. Play in the connecting rod, unusual noise or vibration are typical signs of wear. Follow the manufacturer's service interval for your model, and check the bottom end during a major engine rebuild.

What is a stroker crankshaft?

A stroker crankshaft has a longer stroke than the original. This increases displacement and usually gives more torque. It often requires matching pistons, gaskets or other parts, so check the description on each product.
