The two-size offering helps fine-tune shell height for improved contact with body clips. Limitation: taller posts may raise the shell’s center of gravity on high-speed runs; ensure chassis clearance.

Buying Guide: Key Considerations For RC Car Body Post Mounts
- Compatibility: Confirm your model’s brand and year. Some mounts are tuned for HSP, Redcat, Sakura D4/D3-XI, or Lightning series, while others are more universal.
- Post Length vs. Shell Size: Longer posts suit taller shells; shorter posts work with compact bodies. If in doubt, buy a mix or a 2-length set.
- Outer Diameter: Ensure the mount’s diameter fits your shell’s mounting holes and post sockets without friction or slippage.
- Material and Durability: Plastic mounts are common and lightweight but may wear faster under heavy crashes. Look for high-quality plastics and robust clips.
- Adjustability: Some sets include multiple lengths for flexible tuning. This helps when switching between racing, drifting, and casual driving.
- Replacement and Spares: An eight-piece pack reduces downtime. Consider sets that include spare clips or adapters if you frequently swap bodies.
Frequently Asked Questions
- What is a body post mount and why do I need one? A body post mount secures the RC car’s shell to the chassis while allowing height adjustments for fit and clearance.
- Can I mix different brands of body posts on one RC car? It depends on diameter and length compatibility. Mismatched posts can cause poor fit or detachment during operation.
- How do I know which length to choose? Measure your shell height and the clearance you need over the wheels. Longer posts are for taller bodies; shorter posts for compact shells.
- Are these posts suitable for both nitro and electric RC cars? Yes, most sets are designed for common 1/10 scale models; verify the specific model compatibility in the product description.
- What maintenance is required for body posts? Regularly check clips for wear, ensure posts remain straight, and replace any cracked or bent pieces to prevent shell loss during runs.
- Should I use extension mounts? Extensions are useful when upgrading to larger shells without changing the entire post system. Ensure the extensions fit the existing posts’ outer diameter.
