Performance Upgrade: XRAY 611201 Aluminum Rear Cover

For RC racers focused on lap times and reliability, the XRAY 611201 CNC-machined aluminum rear cover upgrades the NT18 engine with a stiffer, lightweight housing. Built from premium aluminum, the cover balances durability with low mass to keep the engine responsive under load.

Accurate CNC Fit for Better Heat Control

Precision CNC work delivers exact tolerances so the cover mates cleanly with the NT18. A tight fit improves heat transfer and reduces unwanted flex, helping the engine run cooler during long sessions.

Long-Lasting Construction for Track Use

Aluminum resists wear and impact compared to stock components, reducing the need for frequent replacements. The included gasket creates a secure seal to prevent oil leaks and preserve internal pressure.

Simple Swap-In Installation

The package includes four machine screws so you can replace the factory rear cover quickly. No special tools are required, making this a straightforward upgrade for most hobbyists.

The XRAY 611201 CNC-Machined Aluminum Rear Cover brings measurable strength and improved thermal control to the NT18 engine, making it a practical upgrade for competitive drivers and weekend racers.
