DJ Rock PB900 Engine Piston Wrist Pin Bushing Set

Engine Piston Wrist Pin Bushing Set

DJ Rock PB900 is a premium engine piston wrist pin bushing set built for the small end of the connecting rod. It supports smooth pivot motion between the piston and rod assembly and is made for precise alignment under high load and high speed.

Key Features

• Premium-grade bronze alloy construction for low friction and strong load-carrying performance.
• Machined to tight dimensional tolerances for a secure press fit and accurate alignment.
• Built to reduce wear at the wrist pin connection point in internal combustion engines.
• May include oil grooves to support consistent lubrication and longer service life.
• Manufactured to meet or exceed OEM quality standards.

Detailed Description

The PB900 piston pin bushing set is engineered for engines that rely on stable wrist pin movement under repeated heat and pressure cycles. Bronze alloy material helps resist galling and handles elevated temperatures while maintaining a low coefficient of friction. This makes the PB900 a practical choice for Toyota 4Runner, Toyota Pickup, Toyota Celica, Toyota Corona, and Toyota Hi-Lux engine rebuild work where precise rod-to-piston alignment matters. The PB900 part number is also referenced as 4-3964Y and 016-0112 for the same application.

What It Helps Solve

• Excessive wear at the piston pin and connecting rod interface.
• Binding or rough pivot movement in the wrist pin area.
• Loss of alignment between the piston and connecting rod small end.
• Friction-related heat buildup in high-speed engine operation.
• Noise or clearance issues caused by worn pin bushings.

Installation Notes and Tips

Install only in engines listed in the fitment data for this part. Verify bore size, press fit, and lubrication passages before assembly. Because this component is machined to strict specifications, clean the connecting rod small end thoroughly and confirm proper alignment during engine rebuild procedures. Use standard engine machining and measurement practices to ensure correct fitment for Toyota 4Runner, Toyota Pickup, and other listed Toyota applications.

Quality Assurance

DJ Rock PB900 is manufactured to meet or exceed OEM quality standards. The bronze alloy construction and precision machining support consistent performance in demanding engine service.
