Bottom End Parts That Handle Real Power

A strong engine starts at the bottom. Our bottom end selection covers the internal components that keep your block together under stress. You will find forged and stock replacement connecting rods, precision ground crankshafts, and durable pistons designed to handle added boost or nitrous. 

We also stock oiling components that keep pressure consistent on steep climbs, along with timing components and a reliable water pump to prevent overheating during long trail runs. These pieces work together to give your 4Runner a foundation that can survive years of hard use.

Top End Toyota 4Runner 3rd Gen Engine Components For Better Airflow

The top end controls how efficiently your engine breathes, which directly affects power and fuel economy. Our top end parts include:

• Camshafts for improved lift and duration
• Cylinder heads for stronger compression
• Valvetrain components and complete kits for smoother operation

Each of these pieces plays a role in how air and fuel move through your engine. Upgrading your camshaft, refreshing your cylinder head, or replacing worn valvetrain components can noticeably improve throttle response, especially when paired with a complete valvetrain kit.

Turbo and Supercharger Options for More Power

For owners chasing serious horsepower, our forced induction lineup delivers real results. Our turbo kit options include complete turbo kits, individual turbos, turbo manifolds, intercoolers, and boost control parts to keep pressure in check.
