Why Best Upgrades For TRX4M High Trail Are Necessary
From my experience, the stock TRX4M High Trail is a fantastic starting point, but to truly unlock its potential, the best upgrades are essential. These enhancements improve performance, durability, and overall enjoyment. For example, upgrading the suspension and tires gave me better traction and smoother handling on rough terrain, which made trail runs more exciting and less frustrating.
Additionally, I found that reinforcing key components helped prevent damage during tough climbs and crashes. Without these upgrades, the stock parts can wear out quickly or fail under stress, cutting my adventure short. Investing in quality upgrades means my TRX4M High Trail can handle more challenging trails confidently and last longer, making every outing more rewarding.
My Buying Guides on Best Upgrades For Trx4M High Trail
When I first got my Traxxas TRX-4M High Trail, I was excited about its capabilities but soon realized that some upgrades could really enhance its performance and enjoyment. Over time, I’ve tested several upgrades, and here’s my guide to the best ones you should consider to get the most out of your TRX-4M High Trail.
1. Upgraded Tires and Wheels
One of the first things I changed were the tires. The stock tires are decent, but for better grip and durability, I recommend switching to high-traction rubber tires like Pro-Line Hyrax or Maxxis Creepy Crawler. Pairing these with beadlock wheels not only improves grip on rough terrain but also prevents the tires from slipping on the rims, which I found especially useful during rock crawling.
2. Metal Gear Servos
The TRX-4M comes with plastic gear servos, which are fine for light use, but when I started pushing my rig harder, I noticed some gear stripping. Upgrading to a metal gear servo gave me more precise steering control and durability, which made a huge difference during technical trails.
3. Aluminum Chassis Skid Plates
To protect the underside of my TRX-4M, I installed aluminum skid plates. These plates shield the chassis from rocks and debris, which I found essential after a few rough trail runs that left scratches and dents on the stock plastic parts. The skid plates add a bit of weight but offer peace of mind.
4. Upgraded Shock Absorbers
While the stock shocks work okay, upgrading to oil-filled aluminum shocks improved the suspension performance significantly. The smoother damping helped my truck handle bumps and drops more effectively, giving me better control and reducing bounce.
5. Higher Capacity Battery and ESC Upgrade
To extend my run times and get a bit more power, I switched to a higher capacity LiPo battery. Alongside this, upgrading the ESC (Electronic Speed Controller) allowed me to safely handle the increased power without overheating or cutting out. This combo made my TRX-4M more responsive and longer-lasting on the trails.
6. LED Light Kit
For night runs or low-light conditions, I installed an LED light kit. Not only does it look cool, but it also makes driving safer and more enjoyable when visibility is limited. Some kits even include functional brake lights and turn signals, adding realism to the experience.
7. Upgraded Drive Shafts
Finally, I swapped the stock plastic drive shafts for steel or aluminum ones. The upgraded drive shafts are more durable and can handle the torque better, which is especially important if you’re running bigger tires or more powerful motors.
Final Thoughts
Upgrading the TRX-4M High Trail is a rewarding process that can drastically improve your driving experience. From better traction and durability to enhanced control and aesthetics, the right upgrades make all the difference. I recommend starting with tires and servos, then moving on to protective and performance parts as you get more comfortable with your rig. Happy crawling!
