Why RC Car Shocks 75 Mil Are Necessary
From my experience, having RC car shocks with a 75 mil length is crucial for achieving smooth and controlled rides. The 75 mil size offers the perfect balance between flexibility and durability, allowing my RC car to absorb impacts effectively without compromising stability. This means I can tackle rough terrains or jumps without worrying about damaging the suspension or losing control.
Additionally, the 75 mil shocks provide just the right amount of travel to keep my car grounded during high-speed runs. I’ve noticed that shorter shocks tend to make the ride too stiff, leading to bouncing and less traction, while longer shocks can feel too soft and unstable. With 75 mil shocks, I get consistent handling and better overall performance, which makes my driving experience much more enjoyable and competitive.
My Buying Guides on Rc Car Shocks 75 Mil
When I first started looking for RC car shocks with 75 mil size, I quickly realized that there’s a lot more to consider than just the measurement. Over time, I’ve learned what really matters to get the best performance and durability out of my RC car. Here’s what I focus on when shopping for 75 mil RC car shocks.
Understanding the 75 Mil Size
The “75 mil” refers to the length of the shock absorber, which is about 75 millimeters. This size is pretty common for many 1/10 scale RC cars, so knowing this helps me narrow down compatible models and parts. Always double-check your car’s manual or existing shocks to confirm the size before buying.
Material Quality Matters
I prefer shocks made from high-quality materials like aluminum or reinforced plastic. Aluminum shocks tend to be more durable and offer better heat dissipation, which is great for long runs or rough terrain. On the other hand, plastic shocks can be lighter and more budget-friendly but may wear out faster.
Oil-Filled vs. Non-Oil Shocks
One of the biggest improvements I made was switching to oil-filled shocks. They provide much smoother damping and better control over your car’s suspension compared to non-oil types. When buying, I look for shocks where I can adjust the oil viscosity or refill it, so I can fine-tune the ride feel depending on the surface I’m racing on.
Adjustability Features
Adjustability is key for me because I like to tweak my RC car’s handling. Some 75 mil shocks come with adjustable preload collars or pistons with multiple holes for tuning the damping rate. This allows me to customize stiffness and responsiveness, which really helps in different driving conditions.
Compatibility with Your RC Model
Even if the shocks are 75 mil, it’s important to make sure they fit your specific RC car model’s mounting points and shock towers. Sometimes, the mounting hardware or shock ends differ. I always check product descriptions and user reviews to confirm compatibility or whether adapters are needed.
Brand Reputation and Reviews
I tend to stick with brands that have a solid reputation in the RC community. Reading user reviews helps me understand real-world performance and durability. Brands that offer good customer support and replacement parts also get extra points in my book.
Price vs. Performance
It’s tempting to go for the cheapest shocks, but from experience, spending a bit more on quality shocks pays off in the long run. I look for a good balance — shocks that offer solid performance and durability without breaking the bank.
Installation and Maintenance
Lastly, I consider how easy the shocks are to install and maintain. Some shocks come pre-assembled and ready to install, while others require filling with oil or assembling parts. I prefer shocks that come with clear instructions and all necessary hardware to make installation smooth.

By keeping these points in mind, I’ve been able to find 75 mil RC car shocks that improved my car’s handling, durability, and overall driving experience. Hopefully, this guide helps you make a confident choice too!
