INJORA 40mm Big Bore Oil Shock Absorber for 1/24 SCX24 FCX24M Upgrade – 4.3g Each (Black Aluminum & Brass)

Overview

Upgrade your 1/24 scale RC rig with INJORA’s 40mm Big Bore Oil Shock Absorber. Specifically designed for SCX24 and FCX24M chassis, these shocks pair a compact footprint with improved damping dynamics. The 40mm eye-to-eye length combined with a 9mm maximum travel delivers responsive handling over rough terrain while preserving chassis control and stability during acceleration and cornering.

Built with durability in mind, the shocks feature CNC‑machined aluminum caps and bodies, plus a black electroplated steel shaft for a smooth, dependable feel. The big bore design increases internal oil capacity, which helps maintain consistent performance across varied conditions. Internally, these units use bladder seals for steady rebound dampening, and they come with threaded bodies that allow quick pre‑load adjustments to dial in ride height and stiffness without tools.

Key Benefits

• Big bore design holds more oil for smoother damping and a steadier ride over uneven surfaces.
• Threaded bodies enable fast pre‑load tweaks, making setup changes quick at the workbench or on the trail.
• Two included spring rates give you immediate tuning options to suit your chassis and driving style.
• Internal bladder seals support consistent rebound dampening across multiple runs and terrains.
• Bottom rod ends offered in nylon or brass give you lightweight or durable options depending on preference.
• Precision CNC machining and a robust black finish contribute to long‑lasting performance in demanding RC use.

Tuning Tips and Use Cases

For best results, fill the shocks with shock oil (not included) to a light coating—do not fully fill the body. Use the threaded adjusters to set preload after mounting, then test on a familiar course. Start with the softer spring rate and gradually move to the stiffer option as you dial in cornering confidence and stability on high‑speed runs. The combination of bladder seals and the large oil capacity helps maintain a consistent feel through repetitive bounces and small jumps, so you rarely have to guess whether the dampening will hold up on a long session.
