NISSAN TB48 PISTON PINS (PIN D. 23 x PIN L. 63.6) EXTREME DLC

Nissan Patrol TB48 Extreme Duty DLC Coated Piston Pins (23mm Dia. x 63.6mm Length)

Engineering Overview

In extreme-boost or high-RPM Nissan Patrol TB48DE builds, standard tool steel wrist pins flex and gall under immense cylinder pressures, leading to small-end rod bushing destruction, piston pin bore micro-welding, and catastrophic pin boss failure. This performance bottleneck is eliminated by the 23mm x 63.6mm Extreme Duty Diamond-Like Carbon (DLC) Coated Wrist Pins. Featuring a heavy-wall high-strength alloy construction paired with a diamond-hard DLC nano-coating, these pins dramatically reduce sliding friction, eliminate scuffing under oil starvation or cold starts, and prevent pin flexing during high-load drag and sand dune runs.
