INJORA DRX 120mm Dual-Rate Spring Oil Shocks for TRX4 SCX10 1/10 RC Crawler

Enhanced suspension for your TRX4 SCX10 1/10 RC crawler

The INJORA DRX 120mm dual-rate spring oil shocks blend precise engineering with responsive damping, built to accompany serious crawler sessions. CNC‑machined aluminum shock bodies contribute to a sturdy, compact profile, while nylon bottom rod ends introduce a touch of flexible articulation at the joints. This combination supports a balanced chassis feel as terrain shifts beneath the wheels, from smooth pavement to rugged rock faces.

The design centers on a dual-rate spring system that enables smooth small-bump absorption without sacrificing stability during larger impacts. Two spring options, 0.9 mm and 1.0 mm, let you tailor the feel to your rig’s weight and driving style, so you can explore a range of setups without swapping components.

• CNC-machined aluminum shock bodies for durability and a crisp response
• Nylon bottom rod ends add flexible, durable movement at pivot points
• Available in multiple lengths: 80, 90, 100, 110, 120 mm to fit popular TRX4 SCX10 builds
• Two spring rates included: 0.9 mm and 1.0 mm for tuning flexibility
• Smooth action and consistent damping across the full travel range
• Dual-rate design helps absorb small bumps while supporting big impacts

Key specifications are designed for clear, repeatable adjustments. Each shock’s eye-to-eye length options are 80, 90, 100, 110, and 120 mm, with compressed lengths of 62, 67, 72, 77, and 82 mm. Travel ranges from 18 to 38 mm, providing a broad spectrum of suspension feel. Weight per shock runs from 15 to 19 g, helping you tune the overall mass of your crawler. The package includes four shocks and eight extra springs, delivering immediate options to begin tuning before you hit the trail.

• Note: Shock oil is not included. Length is measured eye-to-eye, not overall length.
• In the box: 4 shocks and 8 extra springs for quick setup options

Whether you’re navigating rocky ledges, carving lines through uneven terrain, or testing slow-and-steady crawls, these shocks aim to offer a controllable, predictable feel. The blend of aluminum construction, flexible nylon ends, and the dual-rate spring approach gives you a tunable platform that can evolve with your driving style and course demands, without promising any single outcome.
