Hot Rods: crankshafts, connecting rods and engine parts

Hot Rods has been manufacturing replacement crankshafts and connecting rods since 1993. Its range includes crankshaft assemblies, connecting rod kits, bearings, sealing components and water pump parts. The range focuses on repairing internal engine assemblies and their associated components. Each part number corresponds to a specific application: base your choice on the part you need to replace and the installation requirements, rather than just its appearance in a photograph.

At Motarea you can browse the brand by product family and compare crankshafts, connecting rods and bottom end rebuild kits. These links help distinguish a specific repair from a more extensive job. Always check the contents of the part number: a preassembled unit, a connecting rod kit and a rebuild kit do not contain the same components or require the same assembly work.

Rebuilding the bottom end

When choosing a crankshaft, check the engine version, intended stroke and matching shaft ends, gears and bearing locations. Standard-stroke part numbers and stroker variants must be assessed separately. A change in stroke can affect other components in the assembly; a similar appearance alone does not confirm that the part will fit correctly.

For a connecting rod repair, compare its dimensions, joints and the components included in the kit. If you choose to rebuild the bottom end with a more comprehensive set, check which crankshaft, bearings, seals and gaskets that part number supplies. Compare the contents with the product page and selected application; a product family image does not guarantee that all its kits contain the same items.

Bearings and sealing components

Engine bearings and transmission bearing kits belong to different assemblies. Identify the shaft they run on, their dimensions and the sales presentation of each part number. During a repair, also check the housings and supporting surfaces: replacing a bearing alone does not repair damage to the component that receives it.

For the transmission output area, countershaft seal kits group together components intended for that application. Check the seal, collar, gaskets or washers included in the part number, without assuming that the sprocket is supplied. Also check the crankshaft seals required for the job and their fitting positions.

Water pump repairs and auxiliary components

For the cooling system, there are water pump repair kits and water pump shafts. A sealing kit and a replacement shaft address different needs. To choose the right replacement part, check the leak area and the condition of the shaft, supports and contact surfaces. Also check the included gaskets and which components must be retained or purchased separately.

The catalogue also includes connecting rod fasteners and lubrication system parts. Consult the exact product page to confirm dimensions, contents, compatibility and installation requirements. When fitting internal components, follow the tolerances, clearances, tightening torques and procedures specified for the engine. A sound choice considers both the new replacement part and the components it will work with.
