Overview
Transform the suspension performance of your Redcat Ascent 18 with the Hot Racing Threaded Aluminum Oil-Damped Shocks Full Set. CNC-machined from premium 6061-T6 aluminum and engineered with threaded shock bodies, stainless steel shafts, and rubber bladders, this complete four-shock kit replaces the flexy stock plastic-body shocks (RER28868) with race-grade oil-damped dampers built for consistent, predictable suspension performance.
The threaded body design enables precise, tool-free preload adjustment, while bleeder screws make routine shock maintenance fast and clean. Two spring sets (soft black and stiff silver) are included so you can dial in chassis balance for your specific terrain — exactly what serious Ascent 18 drivers need to get the most from this versatile 1/18 platform.
Key Features
- CNC-machined 6061-T6 aluminum bodies, caps, collars, and retainers
- Oil-damped shocks with rubber bladders
- Threaded bodies for fine preload adjustment
- Bleeder screws for fast, clean maintenance
- Stainless steel shock shafts
- Two spring sets included: soft (black) and stiff (silver)
- Direct replacement for Redcat RER28868 stock shocks
Performance Benefits
- Consistent oil-damped handling — far better than plastic stock shocks
- Improved bump absorption and jump landing control
- Tool-free preload adjustment via threaded bodies
- Easier shock rebuilds with bleeder screws
- Two spring rates for surface-specific tuning
Usage Notes
Requires silicone shock oil of your choice — not included. Start with a 30wt-40wt silicone shock oil as a baseline; thicker oil for high-grip surfaces, thinner for low-grip. Begin with the soft (black) springs front and rear, then mix and match to bias chassis balance.
