Pros:
- Includes two front and two rear assembled shocks with hardware.
- Pre-oiled metal shocks use a sealing design intended to reduce leakage.
- Threaded bodies allow spring-height and preload adjustment.
- Big-bore construction is designed for heavy-duty off-road use.
Cons:
- Fitment is vehicle-specific, so model and dimensions should be checked first.
- The front and rear shocks have different eye-to-eye lengths.
With broad compatibility across Traxxas 1/10 platforms and a 180-day manufacturer warranty, this set is a strong choice when you want an assembled replacement rather than individual shock components.
Best Crawler Tuning Set – INJORA DRX 110mm Shocks
For TRX4, SCX10, and similar 1/10 crawlers, these rc shock absorbers combine CNC-machined aluminum bodies with dual-rate springs. They are supplied with two spring rates and are designed to handle small bumps smoothly while adding support for larger impacts.
Best For: 1/10 RC crawler builders who want interchangeable spring rates and a 110mm eye-to-eye setup.
Pros:
- Dual-rate spring design balances small-bump response with impact support.
- Includes four shocks plus eight extra springs in two rates.
- Aluminum bodies and nylon lower rod ends provide a durable, flexible combination.
- Available in multiple lengths for different crawler setups.
Cons:
- Shock oil is not included.
- Length is measured eye-to-eye, so chassis dimensions must be compared carefully.
- Not recommended for children under 14.
This set is a flexible option for crawler suspension tuning, especially if you value spring-rate experimentation. Plan to supply shock oil separately and verify the 110mm center-to-center measurement before ordering.
Best 1/8 Rear Upgrade – 130mm Adjustable Shocks
These 130mm rc shock absorbers are a four-piece rear-shock set for many 1/8 off-road cars, buggies, and truggies. Their pre-oiled aluminum alloy bodies, big-bore design, and adjustable threaded springs are intended to improve damping and stability during demanding driving.
Best For: 1/8-scale rear suspension replacements for compatible Arrma, Traxxas, and other off-road platforms.
Pros:
- Includes four pre-oiled aluminum alloy rear shocks.
- Big-bore design and moderate spring firmness target off-road stability.
- Threaded bodies allow spring-position and preload adjustment.
- Listed compatibility covers numerous 1/8 cars, buggies, and truggies.
Cons:
- Designed as rear shocks, not a complete front-and-rear set.
- Buyers should verify the 130mm eye-to-eye measurement against the original shocks.
- The spring nut should be tightened before use to help prevent oil leakage.
The broad compatibility list and two-year manufacturer warranty make this an appealing replacement set, but the 130mm center-to-center dimension and rear-position design are essential fit checks.
Best Compact Crawler Fit – INJORA DRX 100mm Shocks
These 100mm rc shock absorbers are made for TRX4, SCX10, and comparable 1/10 RC crawlers. Their aluminum bodies, flexible nylon lower rod ends, and dual-rate spring setup provide a tunable suspension package for both light trail bumps and harder impacts.

How We Picked These Rc Shock Absorbers
We selected these options across common RC scales and vehicle platforms, including 1/10 crawlers, 1/8 vehicles, Traxxas models, SCX24 and TRX4M builds, and smaller 1/12 to 1/16 cars. We prioritized compatibility information, adjustable or oil-filled designs where useful, aluminum construction, spring options, included quantities, and suitability for replacement or performance upgrades.
Because shock fit is highly vehicle-specific, verify the manufacturer’s dimensions, eyelet style, mounting hardware, and compressed and extended lengths before ordering. A shock that looks similar may still alter suspension geometry or fail to clear the chassis and tires.
Quick Comparison
- Best for broad 1/10 replacement needs: The assembled four-piece 1/10 set is a convenient starting point for replacing front and rear dampers.
- Best for crawler tuning: INJORA’s 100mm and 110mm dual-rate oil shocks offer more setup flexibility for compatible TRX4 and SCX10 builds.
- Best for larger vehicles: The 130mm 1/8-scale adjustable shocks suit models that require longer travel and larger hardware.
- Best for compact platforms: The 40mm SCX24 and 59mm TRX4M options target smaller crawlers with more specific fit requirements.
- Best for small RC cars: The 72mm four-piece set is intended for 1/12, 1/14, and 1/16-scale applications.
Key Buying Factors for Rc Shock Absorbers
Length and Mounting Geometry
Measure the original shock from mounting center to mounting center, both extended and compressed. Matching length helps preserve ride height, suspension travel, driveshaft angles, and clearance. Also check ball diameter, screw size, spacers, and whether the shock uses a standard or vehicle-specific eyelet.
Oil-Filled Versus Friction Designs
Oil-filled shocks generally provide more consistent damping than basic friction dampers. Silicone oil viscosity controls how quickly the suspension responds: lighter oil reacts faster over small obstacles, while heavier oil slows movement and can reduce bouncing. Temperature and spring choice also affect behavior.
Spring Rate and Preload
Dual-rate springs and threaded bodies provide more tuning range, but they are not automatically better for every build. Choose a spring that supports the vehicle without holding the suspension excessively high. Use preload collars to set ride height, not to compensate for a fundamentally incorrect spring rate.
Construction and Serviceability
Aluminum bodies can improve durability and thread quality, while plastic designs may be lighter and less expensive. Look for replacement seals, bladder or cap design, threaded adjustment collars, and accessible refill points if you expect to rebuild or retune the shocks.
Who Should Buy Which Rc Shock Absorbers?
Choose a complete four-piece set if you need a straightforward replacement for a matching front-and-rear setup. Choose adjustable oil shocks if you tune suspension performance for crawling, trail driving, jumping, or different terrain. Choose big-bore or longer shocks only when your chassis supports the added diameter and travel.
For a small-scale crawler, prioritize exact platform compatibility over generic adjustability. For a heavy 1/10 or 1/8 truck, focus on shaft strength, spring support, oil capacity, and mounting hardware. Before installation, compare all dimensions with your original parts, set ride height evenly, and check for binding through the full suspension range.
