INJORA DRX 90&100mm Dual-Rate Shocks for TRX4 SCX10 1/10 RC Crawler

Engineered for precision on rugged trails

The INJORA DRX dual-rate shocks are built to bring controlled, confident damping to your 1/10 scale crawler. With CNC-machined aluminum shock bodies and nylon bottom rod ends, these components balance stiffness with just enough give, letting your truck glide over uneven terrain without losing line or traction. The dual-rate spring design is tuned to respond smoothly to small bumps while offering robust support during bigger impacts, helping you maintain contact with the surface in real-world trials.

Key technical advantages

• CNC-machined aluminum shock bodies deliver a precise, durable core with a clean, consistent feel during long sessions.
• Nylon bottom rod ends add flexible articulation for smoother suspension travel.
• Length versatility available in 80, 90, 100, 110, and 120 mm to fit a range of TRX4/SCX10 builds and ride heights.
• Dual-rate springs include 0.9 mm and 1.0 mm options for fine-tuning alignment with terrain and weight distribution.
• Smooth action and consistent damping across the range supports predictable handling under varied speeds and surfaces.
• Lightweight per shock at 15–19 g, helping maintain overall lower unsprung mass for quicker response.

Important notes: shock oil is not included, and the length specification is measured eye-to-eye (center-to-center), not the overall length. This keeps setup clear when dialing in your chassis for different courses or obstacle layouts.

Real-world use cases

Envision your trail runs where the rig encounters small rocks and roots, then transitions to larger drops or steep angles. The dual-rate springs can soften the initial contact with minor irregularities while providing solid support as the wheel traverses larger obstacles. The aluminum bodies resist flex fatigue on long sessions, and the nylon rod ends help the suspension articulate smoothly without binding. With multiple lengths to choose from, you can tailor ride height and stiffness to your preferred driving style—whether you’re crawling up a technical line or cruising a rugged course.
