Pontiac Firebird Crankshaft

Pontiac Firebird Crankshaft converts the straight up and down punch of the pistons into the smooth spin that ultimately drives the wheels. It is the hidden hero of all sporty coupes of this line. The Crankshaft of the car is deep inside the engine block. It has offset throws. On these throws, connecting rods get attached. When these rods push, the Crankshaft rotates. The Crankshaft gives this rotational energy to the transmission. This further powers the axles and tires of the car. Across successive Firebird generations, Pontiac offered two main crank styles. Early and lower output versions relied on cast iron Crankshafts that were strong enough for daily cruising yet economical to mold. The high horsepower editions, however, received forged steel units that shrug off heavier loads and higher revs easily. Each Crankshaft is precision machined for the full life of the vehicle, regardless of material, as long as oil is clean and plentiful. The journals can become scored, clearances loosened, and engine knock caused by neglect, dirt, or low lubrication. Replacing a Crankshaft is tough and time-consuming. That said, if you ensure the bearings are well-aligned, add fresh grease, and use proper torque, you can restore factory smoothness. In this way, the legendary Pontiac and its Firebird spirit will keep roaring down the road.

Each OEM Pontiac Firebird Crankshaft we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
