YIKONG YK4107PRO 1/10 RC Crawler Upgrade Parts
As one of the premium models in the YIKONG crawler family, the YK4107PRO already delivers impressive off-road performance and refined mechanical design. But if you’re aiming to tackle more complex terrains and more hardcore challenges — some key upgrades are essential. These not only enhance stability and drivability but also extend the life of your rig, helping you conquer every crawling course with confidence.
We’ll introduce several upgrade parts for the YK4107PRO — including a full armor set, front and rear wheel weights, C-hub weights, and front and rear shock mounts — each of which has been battle-tested and delivers noticeable performance improvements!
1. Full Armor Set: Max Out Your Rig’s Protection
This metal armor kit is made of 304 stainless steel and weighs 92g. The included accessories are a front bumper armor (with dimensions of 85.64mm x 38.11mm x 8.35mm), a middle gearbox base armor (with dimensions of 108.65mm x 57.8mm x 12mm), and front and rear axle armors (2 pieces, with dimensions of 41.7mm x 42.8mm x 14.2mm).
Why upgrade? During off-road crawling, key areas like the chassis, gearbox, servo, and suspension arms are vulnerable to hits, scrapes, and impact. The stock plastic guards offer limited protection.
Upgrade effect: By installing a full set of metal armor (chassis skid plates, gearbox guards, servo protector, etc.), your rig’s impact resistance will improve significantly. Whether you’re smashing through rocks or scaling steep slopes, you can rest assured that vital components are well-protected. It’s not just about durability — it’s also protecting your investment.
2. Front & Rear Wheel Weights: Better Traction and a Lower Center of Gravity
The front wheel counterweight is made of brass, weighing 204g, with dimensions of 43.93mm x 37.94mm x 16mm. The rear wheel counterweight is also made of brass, weighing 128g, and its dimensions are 44mm x 30.8mm x 13.05mm.
Why upgrade? Crawling over uneven surfaces or inclines often leads to wheel spin or tipping due to insufficient traction or a high center of gravity.
Upgrade effect: Adding wheel weights (usually made of lead or brass) on all four wheels increases downward pressure, improving tire contact with the ground. Front wheel weights enhance pulling power, while rear wheel weights help maintain balance during climbs. The result? More stable handling, especially on rocky slopes and during controlled descents.
3. C-Hub Weights: Optimize Front Axle Pressure for Confident Climbing
C Hub size:24.5mmx26.5mmx23.1mm
Why upgrade? The C-hub area — where your steering knuckles are supported — plays a crucial role in front axle performance. Its mass and balance directly affect front-end pressure and traction.
Upgrade effect: Replacing the stock hubs with metal C-hubs with built-in weights not only boosts front axle strength but also increases front tire pressure, preventing the nose from lifting during climbs. This significantly improves grip and control in technical, slow-speed, obstacle-heavy terrain.
4. Front & Rear Shock Mounts: Stronger Support, Smoother Travel
The front and rear shock mounts are made of aluminum, weighing 35g and measuring 38mm x 28.77mm x 15.84mm.
Why upgrade? The stock plastic shock mounts may flex or break under heavy loads, disrupting suspension geometry and damping performance.
Upgrade effect: Upgrading to CNC aluminum shock mounts ensures a much more stable shock position and allows fine-tuning of shock angles. Paired with high-quality dampers, this leads to smoother suspension travel, better compression and rebound balance, and a more linear off-road experience overall.
