Why Best Upgrades for TRX4M High Trail Are Necessary
From my experience with the TRX4M High Trail, the stock setup is great for getting started, but upgrading it truly transforms the performance and enjoyment. The best upgrades are necessary because they address the truck’s limitations, such as improving durability, enhancing traction, and boosting overall handling on rough terrain. Without these enhancements, I found myself held back by worn-out parts and less-than-ideal control when tackling challenging trails.
Moreover, upgrading key components like the suspension, tires, and drivetrain allows me to customize the truck to my specific driving style and the environments I explore. Whether climbing rocks or powering through mud, the right upgrades give me confidence that my TRX4M can handle whatever I throw at it. In short, these improvements aren’t just about making the truck look better—they’re essential for unlocking its full potential and extending its lifespan during intense trail runs.
My Buying Guides on Best Upgrades For Trx4M High Trail
Upgrading my TRX4M High Trail has been one of the most rewarding experiences in my RC journey. Whether you’re looking to improve performance, durability, or aesthetics, the right upgrades can make a huge difference. Here’s what I found to be the best upgrades for the TRX4M High Trail based on my hands-on experience.
1. Enhanced Tires and Wheels
The stock tires on the TRX4M High Trail are decent for general use, but I found that upgrading to high-traction, soft compound tires significantly improved off-road grip. I recommend tires like the RC4WD Interco Super Swamper or Pro-Line Hyrax for better crawling and trail performance. Pairing them with beadlock wheels not only looks great but also secures the tires firmly, allowing me to run lower pressures without fear of them popping off.
2. Upgraded Shocks
The stock shocks are okay, but switching to oil-filled, adjustable shocks made a noticeable difference in ride smoothness and handling. I personally went with Gmade GTS shocks for their durability and tunability. These help in absorbing rough terrain impacts and give me the ability to fine-tune the suspension to match different trail conditions.
3. Metal Upgrade Kits
To increase durability, I installed metal upgrade parts such as aluminum steering knuckles, link rods, and chassis braces. These upgrades reduce flex and wear, especially when I push the truck through challenging obstacles. Metal parts also add a nice weight bias, improving stability on climbs.
4. Motor and ESC Upgrade
For better power and control, I swapped the stock motor and ESC for a brushless combo. A 3500-4000KV brushless motor paired with a waterproof ESC gave me more torque and top speed without compromising battery life. This upgrade is essential if you want to tackle tougher terrain or run faster on open trails.
5. Battery Upgrade
Upgrading to a higher capacity LiPo battery extended my run time significantly. I recommend a 2S or 3S LiPo pack compatible with your ESC for the best balance of power and weight. Just remember to check that your motor and ESC can handle the increased voltage.
6. Lighting Kits
Adding LED light kits enhanced both the look and functionality of my TRX4M High Trail. I installed front and rear lights, along with rock lights underneath, which came in handy during dusk or night runs. It also adds an authentic trail truck vibe that I really enjoy.
7. Winch Upgrade
A functional winch is a great addition for recovery situations. I opted for a waterproof, metal-geared winch that mounts easily on the front bumper. It’s saved me more than once when I got stuck on tricky trails and adds to the realism of the build.
8. Body and Scale Accessories
To complete the look, I added scale accessories like roof racks, spare tire mounts, and side mirrors. These not only enhance realism but also provide practical storage options for trail essentials.
Final Thoughts
Upgrading my TRX4M High Trail has been a balance of improving performance and adding personal touches. Start with the basics like tires and shocks, then move on to durability and electronics as you get more comfortable. Each upgrade made my truck more capable and enjoyable, and I’m sure you’ll find the same satisfaction customizing yours.
Happy crawling!
