The Redcat Racing RER42149 is a set of high-performance oil-filled rear shocks engineered for the Ascent-18 Apex. These shocks are distinct from the front versions because they include only one internal O-ring travel limiter.
Vehicle Compatibility
Specifically tuned for the rear weight bias and articulation needs of the Apex chassis:
-
Ascent-18 Apex (Direct factory replacement)
-
Ascent-18 / Scout II (Performance upgrade for more consistent dampening)
Key Features
-
Apex-Tuned Travel: Features a single internal O-ring on the shaft to limit down-travel just enough to prevent "unloading" on steep descents without sacrificing the flex needed for rock crawling.
-
Aluminum Shock Caps: Equipped with premium aluminum caps that provide a superior seal and increased durability over standard all-plastic shock sets.
-
Hydraulic Dampening: Pre-assembled and oil-filled to eliminate the "pogo-stick" bouncing effect, giving your 1/18 crawler a more planted, professional feel.
-
Precision Springs: Comes with factory-spec springs optimized for the Apex's rear-end weight, ensuring the vehicle sits at the proper ride height for maximum stability.
