How to Choose best rc crawler shocks reviews
Shock Length and Travel
The length of your shocks determines suspension travel and ride height. Shorter shocks like 80-100mm work great for compact builds with lower centers of gravity, while 110-120mm options provide extended articulation for serious rock crawling.
Measure your crawler’s mounting points carefully before buying. The shock length needs to match your chassis geometry, or you’ll struggle with installation and poor suspension performance.
Construction Quality and Materials
CNC-machined aluminum shocks offer the smoothest operation and tightest tolerances but cost more. Cast aluminum options provide good durability at lower prices, though they may have slightly more friction in the shaft movement.
Look for anodized finishes that resist corrosion and wear. The shock bodies should feel solid without flex, and the shafts should slide smoothly without binding or catching.
Spring Design and Adjustability
Single-spring shocks work well for most recreational crawling. Dual-spring designs offer progressive damping that starts soft and firms up under compression, providing better control across varying terrain.
Adjustable tension and preload settings let you fine-tune suspension characteristics for different driving styles. Threaded shock bodies make preload adjustments quick and easy without disassembly.
Oil vs Dry Operation
Oil-filled shocks provide smoother, more consistent damping and better control over rough terrain. Pre-filled options save setup time, while empty shocks let you choose your preferred oil weight for custom tuning.
Some budget shocks work without oil using spring tension alone. While this simplifies maintenance, oil-filled dampers generally perform better for serious crawling applications.
Compatibility and Mounting
Check that shocks fit your specific crawler model’s mounting points and geometry. Popular platforms like SCX10, TRX-4, and D90 have different requirements for shock length and mounting hardware.
Consider whether you need specific mounting angles or adjustable end links. Some crawlers benefit from shocks with multiple mounting positions for fine-tuning suspension geometry.
Frequently Asked Questions
Do I need to fill RC crawler shocks with oil?
Most quality shocks perform best when filled with proper shock oil, which provides consistent damping and smooth operation. Some budget options work without oil using spring tension alone, but oil-filled shocks generally deliver superior performance on rough terrain.
What shock length is best for my crawler?
The ideal shock length depends on your crawler’s chassis and mounting points. Measure from mounting hole to mounting hole on your current shocks, or check your vehicle’s specifications for recommended shock lengths between 80-120mm.
Can I use different shock oils to tune performance?
Yes, heavier oil weights create firmer damping for better control on rough terrain, while lighter oils provide softer damping for smoother operation on mild trails. Most crawlers work well with 30-50 weight shock oil.
How often should I replace crawler shocks?
Replace shocks when you notice oil leaking, inconsistent damping, or visible damage to shock bodies or shafts. With proper maintenance, quality shocks can last years of regular crawling before needing replacement.
Are CNC-machined shocks worth the extra cost?
CNC-machined shocks offer tighter tolerances, smoother operation, and better consistency than cast options. For competitive crawlers or perfectionists, the improved performance justifies the higher price, but budget builders get good results from quality cast aluminum shocks.
Final Thoughts
The Pro-Line Racing Pro-Spec Scaler Shocks deliver the smoothest performance for serious crawlers, while the INJORA 120mm set offers excellent CNC quality at budget-friendly pricing.
Consider shock length, construction quality, and whether you want dual-spring adjustability or simple reliability. Match the shock specifications to your crawler’s mounting points and your performance expectations.
For most crawlers, investing in quality shocks transforms suspension performance and makes challenging terrain much more manageable.
