Hot Rods is what engine builders reach for when a bottom end lets go. The brand has spent decades doing one job and doing it properly: forged crankshafts, plated connecting rod kits, main bearing and seal kits, counter balancers, transmission bearings, output shafts and water pump kits for the ATVs, dirt bikes, side-by-sides and personal watercraft that get ridden hard. These are not shelf-stock bearings in a bag. Cranks are forged and ground on centers, rods run plated pins and matched bearing packages, and the kits ship with the seals and gaskets you actually need to close the cases in one sitting, instead of three parts orders spread over two weekends.

Riders find Hot Rods the same way every time. A rumble at idle, vibration that will not tune out, water in the oil after a pump seal fails, or a rod knock that shows up on the last lap of the day. Rebuilding with a complete bottom end kit puts the crank, rod, mains and seals in fresh together, so the engine goes back to holding rpm and stops feeding metal into the transmission. IPD Racing stocks the range across four machine types, listed by year and model so you are shopping by machine instead of cross-referencing bearing numbers on a vendor chart at midnight, and our team confirms the correct part number against your machine before the order goes out — because an engine internal that is close is an engine internal that costs you the season.
