RcThjia 72mm Oil Shock Absorber Set
The RcThjia 72mm oil shocks are designed for front and rear mounting on 1/12 to 1/16 scale RC cars, including WLtoys and MJX models. The aluminum threaded bodies allow quick pre-load adjustments, enabling precise tuning for bumpy terrains and jumps. Internally, real oil dampening — with bladder seals — provides consistent rebound and reduces oil leakage, helping maintain stable traction across varied surfaces. This set is compatible with multiple 1/16 and 1/12 chassis, making it a flexible upgrade for a range of builds.
ARRAROWN 4PCS 1/10 Shocks Front & Rear Damper Set
These pre-oiled shocks come as a complete front and rear damper set for popular 1/10 scale Traxxas models and other compatible platforms. The metal bodies increase durability, while the pre-oiled design simplifies installation and reduces break-in time. The big-bore construction is especially suited to heavy off-road use and aggressive landings, helping to smooth out rough terrain and maintain tire contact for improved control and cornering performance.
RcThjia Oiled Shocks Upgrade 66mm/72mm
This RcThjia set offers an extended travel design with 72mm front shocks and 66mm rear shocks, expanding suspension stroke for enhanced off-road performance. The aluminum bodies are hard-anodized and threaded for easy pre-load adjustments. Real oil dampening, sealed with a bladder system, minimizes leakage while maintaining consistent rebound. It’s a versatile upgrade for WLtoys, MJX, HBX, and similar models, enabling more controlled landings and smoother rides on uneven terrain.
Fraizoe RC 66mm Oil Filled Shocks
The Fraizoe 66mm oil-filled shocks provide direct compatibility with a broad array of 1/12 to 1/16 scale vehicles, including WLtoys 144001, 124019, MJX 16208, HBX, and SCY models. The kit emphasizes premium aluminum construction with a hard-anodized finish, alongside true oil-filled damping for smooth, predictable responses over rough terrain. The wide compatibility makes it a solid upgrade option for users who own multiple models or frequently swap parts between platforms.
ARRAROWN 4PCS 5862 Front & Rear Shocks
These ARRAROWN shocks are designed as a replacement for 1/10 scale Traxxas models and similar platforms that use the 5862 designation. They come pre-oiled and feature a big-bore design to manage heavy terrain and jumping. The metal shock bodies increase durability and reduce wear over time, helping maintain consistent performance, especially during long sessions or aggressive driving styles.
Buying Guide
Key considerations when selecting RC car shocks include length, travel, and mounting compatibility. Longer shocks (like 72mm front with 66mm rear) increase suspension travel, which improves wheel contact on uneven terrain but may require chassis adjustments for proper fitment. Big-bore shocks generally offer better heat dissipation and durability under heavy use, while pre-oiled or oil-filled designs reduce setup time and deliver smoother damping than friction dampers. Material quality matters; aluminum bodies are lighter and more resistant to corrosion, contributing to longer life in demanding environments. Always confirm the shock length and mounting style with your specific chassis and existing parts before purchase, as incorrect fitment can affect steering, ride height, and overall handling. For multi-model hobbyists, choosing shock sets with broad compatibility can simplify upgrades across several cars. Consider maintenance needs as well; some sets require adding shock oil and periodic seals checks to maintain optimal performance.
In summary, the options above cover a spectrum of needs—from rugged, big-bore designs for off-road bashing to precision oil-filled dampers that emphasize smooth, controllable handling. Whether you prioritize ease of installation, durability, or travel, there is a suitable upgrade among these five choices to fit your RC car and driving style.
