INJORA 87g IR40 Truck Body Shell with Tube Cage for TRX4M - Upgrade

In this review the INJORA 87g IR40 truck body shell is evaluated for hobbyists who want a clean, easy upgrade for a 1/18 TRX4M Defender or Bronco chassis. The biggest reason to consider it is the combination of a high quality ABS hard body and a practical rear tube cage that improves scale appearance while keeping access to the chassis simple; installation is straightforward and the clipless front plus hook-and-loop rear hinge make battery and electronics access fast for trail repairs.

Key Features

• High quality ABS: The rigid ABS hard body gives a realistic, durable shell that holds shape and detail during casual trail use.
• Rear tube cage: The integrated tube cage improves the truck's scale look and protects the rear body section from light impacts.
• Easy installation: The shell secures to the chassis with only four screws and a simple twist, so it can be fitted quickly without complex trimming.
• Front clipless mount: The clipless front mounting design reduces hardware and speeds mounting while maintaining a secure fit on TRX4M rails.
• Hook-and-loop hinge: The rear hook-and-loop hinge lets the body swing up for instant access to the battery and chassis without removing the shell.
• Multiple color options: Available in white, gray, green and blue to let owners match or customize their rig's appearance.

Who It's For

This body shell is best for TRX4M owners running a stock TRX4M Defender Bronco rail setup or those using the INJORA Universal TRX4M chassis who want an attractive, easily removable body that fits with INJORA 1.3' wheels and tires. It suits beginners and intermediate hobbyists who value fast serviceability on the trail and a stronger visual presence for scale setups.

Those who need heavy-duty impact protection or expect professional competition-level abuse should look for reinforced or metal-bodied alternatives, since customers have reported some durability concerns and occasional screw stripping under heavy use.

Pros & Cons

Cons

• Some users reported issues with the supplied screw quality and potential durability limits under heavy use.
