Buying Guide: Key Considerations For RC Leaf Spring Kits
What kind of crawler and scale is your project?
Most 1/10 scale crawlers use leaf springs in the HighLift or genuine spring setups. Confirm the chassis compatibility (D90, WPL variants, or similar) before selecting a kit.
Material and durability
Steel leaf springs offer higher load capacity and wear resistance. Look for solid steel construction and corrosion-resistant finishes for longevity over long-term use.
Installation effort
Choose kits that advertise easy installation and minimal modification when you want a straightforward upgrade. Some kits include mounting hardware, which saves time.
Load capacity vs. flex
Leaf springs that increase payload may reduce tire articulation. If you need aggressive flex for off-road trails, balance stiffness with articulation needs.
Compatibility and mounting
Verify screw size, mounting points, and length (for example, 120mm vs. other lengths). Incorrect fitment can create alignment issues or bind suspension travel.
Maintenance and replacements
Steel leaf springs hold up well, but check for wear or deformation after use. Replacement availability and ease of sourcing spares are practical considerations.
FAQ
-
Are leaf spring kits compatible with all 1/10 scale crawlers?
Leaf spring kits generally fit common HighLift and D90-type chassis. Always confirm model compatibility and mounting points before purchase.
-
Do these kits require modification to install?
Some kits are designed for plug-and-play installation, while others may require minor adjustments. Check product notes for specifics.
-
Will heavier springs affect steering or suspension travel?
Stiffer springs can alter handling by increasing load capacity but may reduce articulation. Plan for balance with your steering setup and weights.
-
Can I mix brands for a custom suspension?
Mixing components is possible but can lead to uneven handling. It’s best to pair matching kits or ensure compatible mounting geometry.
-
What is the expected maintenance for steel leaf springs?
Regular inspection for deformation or rust is recommended. Clean and inspect mounting hardware to maintain reliable performance.
