|---|---|---|
| MOHERO Steel Leaf Springs Set | 120mm steel leaf springs, M3 screws | 1/10 RC D90 chassis |
| Black 1 Set Leaf Springs Set HighLift Chassis | Metal construction, ready-to-fit | 1/10 Crawler D90 |
| RC4WD Z-S0570 Red Super Soft Flex Leaf Springs | Soft flex, high articulation | Tamiya F-350, Hilux, RC4WD trails |
| Hobbypark Stiff Leaf Spring Suspension | Stiff steel leafs, higher payload | 1/10 RC Rock Crawler, D90 |
| Skymaker Replacement Leaf Springs | Metal leaf springs for C8815/C8835 | C8815/C8835 upgrades |
MOHERO Steel Leaf Springs Set Upgrade
The MOHERO leaf springs are engineered from durable steel with a black finish. Each set includes a 120mm length and M3 screw threads for straightforward installation, designed to fit 1/10 scale D90 chassis without modification. These leafs provide robust support for demanding crawling courses while preserving articulation through multiple leaf configurations. Installation is described as simple and does not require chassis alterations, making them a practical upgrade for users seeking long-lasting performance under load.
Black 1 Set Leaf Springs For D90
This Black 1 Set Leaf Springs upgrade is advertised as a direct fit for 1/10 scale D90 crawlers. The kit emphasizes a metal construction approach, aiming to deliver improved rigidity and reliable spring behavior. It sits well with users who want a solid, straightforward upgrade without extra tuning or customization. The product promises a clean install and enhanced stability on rough terrain through a traditional leaf spring layout.
RC4WD Z-S0570 Red Super Soft Flex Leaf Springs
RC4WD’s Z-S0570 set features red super soft flex springs, designed to increase articulation for enhanced wheel travel. The kit includes four leaf springs and is noted to be compatible with popular platforms such as the Tamiya F-350, Hilux, and RC4WD Trail Finder builds. The softer material yields greater flex, helping crawlers navigate uneven terrain more smoothly, albeit with a potential trade-off in load stability under heavy payloads. These springs are ideal for riders prioritizing articulation above all.
Hobbypark Stiff Leaf Spring Kit
The Hobbypark kit includes two sets of stiff steel leaf springs designed for 1/10 scale RC crawlers, including D90 compatibility. The design emphasizes higher payload capacity, offering a firmer suspension feel that can improve stability on steep climbs and loaded configurations. This option suits builds where durability and load-bearing capability are prioritized over maximum articulation and soft flex.
Skymaker Leaf Springs For C8815/C8835
Skymaker offers metal leaf springs aimed at upgrading C8815 and C8835 models. The set emphasizes compatibility with specific RC crawler upgrades, positioning itself as a straightforward path to improved rigidity without altering overall chassis geometry. Suitable for builders who favor metallic construction and a reliable, no-frills upgrade for better stability in off-road conditions.
Buying Guide
- Material and durability: Steel leaf springs tend to be more durable than some alloys, offering longer service life under load. Consider whether you need maximum rigidity for payload or more flex for terrain undulations.
- Flex vs. stiffness: Softer flex springs increase articulation and wheel contact on uneven surfaces, while stiffer springs reduce body roll and improve payload handling on steep climbs. Choose based on terrain and driving style.
- Compatibility: Verify model compatibility with your 1/10 scale crawler (D90, Tamiya, Hilux, etc.). Some kits are designed for specific chassis and may require additional adapters.
- Installation ease: Some sets are direct fits with no modification, while others may require minor chassis adjustments or additional hardware. Review screw sizes (e.g., M3) and mounting points.
- Articulation goals: For rock crawling, higher articulation can help maintain traction; for torque-heavy climbs, stiffer springs may preserve stability and control.
- Maintenance: Metal leaf springs benefit from occasional lubrication and inspection for wear at staple joints. Inspect for cracks or deformation after hard impacts.
- Durability under load: If you frequently drive with heavy accessories or payload, prioritize stiff, load-bearing leaf springs to prevent sagging and excessive axle droop.
- Cost and availability: Compare price points and stock levels across brands. Some brands offer multi-pack options that can reduce per-spring cost and simplify upgrades over time.
