INJORA 45g LCG Aluminum Universal Chassis Frame Kit for 1/18 TRX4M Upgrade

Rugged, CNC-machined aluminum chassis for 1/18 scale crawlers

Engineered with precision, the INJORA 45g LCG aluminum universal chassis frame blends a lightweight profile with durable construction. The black anodized finish adds a premium look while enhancing rigidity, helping the frame resist flex during tough climbing and obstacle negotiation.

Key design benefits

• Sturdy CNC-machined aluminum with a black anodized finish for durability and style.
• Multiple shock mounting points enable precise suspension tuning to match terrain and driving style.
• Layout flexibility allows changes that may improve climbing performance and handling.
• Detachable ESC tray with adjustable height supports different power systems and prevents plug compression in certain body configurations.

Installation and compatibility

• A screw-hole design lets you fix screws directly to the rails, often without separate nuts.
• Supports lay-down and stock servos, all 1/18 TRX4M stock bodies (Defender, Bronco, High Trail K10, F-150), and INJORA IR40/IR60 bodies.

What you’ll need to install: a 0.05 inch hex driver (1.27–1.3 mm) and a 1.5 mm hex driver. The kit is designed for hobbyists who value precise fit and adaptable configurations, offering possibilities for layout tweaks and improved control without altering core drive components.

Notes and usage ideas

Small changes in frame layout or suspension setup can influence how a crawler handles steep slopes, rocky approaches, and uneven surfaces. This chassis provides a flexible platform for a range of 1/18 TRX4M builds while aiming to keep the upgrade process approachable.
