As many of you know, the Revo 3.3 is a high-performance 4-wheel drive monster truck that is very capable on the track. The Revo 3.3 has won nearly every major monster truck racing event, and has taken home the gold in every national championship that it has entered. However, these wins weren't achieved by pulling it out of the box, dropping in a random set up at the track, and pulling the trigger. There are many things to consider when preparing your Revo for serious competition. This applies to all levels of racing. Even if you're a weekend warrior at your local track, a better prepared truck will always give you an advantage over the competition, no matter who you are.


This guide is designed to compliment and enhance my previous set up series on the Revo (Revo Performance Setup Guide part 1, 2 & 3). The original Revo setup guide will assist you by explaining the basics of tuning the Revo suspension as well as many other aspects of the truck. This Revo 3.3 setup guide will get your Revo up-to-date with current setup tips and tricks that I (along with other Traxxas team drivers) are currently using to achieve maximum performance from our race Revos. I highly recommend referring to the original setup series for additional info or questions you may have when reading this guide.


I'll walk you through the "how's & why's" of each tip and modification that I use as I rebuild my personal Revo 3.3 for its next race. I'll also follow up with a Revo 3.3 base setup sheet to follow for prepping your own Revo 3.3 for your next race. Let's get started.

There are five things to remember before setting up your chassis and suspension:


1) Mechanics first:
It's very important to understand that an ill-handling truck is often caused by a mechanical problem rather than by a particular setting. For example, a screw fastener may be missing or a suspension component may be bent or broken, inhibiting the suspension from moving freely. If the truck is not mechanically sound, adjusting the settings will have little or no benefit. Therefore, it must be assumed that the truck is mechanically functioning properly before moving forward. This includes the following:

  • No binding in the suspension or steering, front/rear
  • Smooth and consistent operation of the shock absorbers
  • No excess bind or drag in the drive system
  • Suspension settings are equal, left to right

2) Evaluate before making changes:
Effective tuning begins with an effective evaluation of the truck's performance. Rather than conclude your truck is "just not working", try to analyze and pin point where (in a certain turn or jump section) or when (accelerating, braking, etc.) the truck is not performing well. It can be helpful to ask yourself specific questions like 'Do I have enough steering into/through/out-of the turn?'; 'Is the truck accelerating well or is it spinning out when I apply throttle?'; 'Is the truck responsive enough or does it feel too reactive or twitchy?' Knowing which areas are not working as well as they should, will allow you to narrow down the setting that you should try adjusting.


3) Tuning is usually a compromise:
Improving one area of performance typically means reducing performance in another area. By increasing steering into a turn, you often lose steering out of the turn. By gearing for more acceleration, you will lose a little top speed. Stiffening the suspension may increase responsiveness, but may make the truck more difficult to drive. It's all about the best possible compromise and how you feel when driving the truck.


4) Only make one change at a time:
To effectively tune your race truck, it's best to make one change at a time. If you make more than one change at a time, it will make it difficult to determine which change made the difference. Even if multiple changes improved the truck's performance, it would be difficult to tell which change made the best result. It is possible this can backfire and decrease the truck's performance, which will leave you not knowing which change was most effective.


It's best to just make one change and if it improves performance, then continuing in that direction will help get you to where you want to be. If the change causes a negative outcome, then you'll know exactly what the change affected and will help you better learn what you should or should not change at the next track you race on. If you do not feel a change in the truck from making an adjustment, then try timing your laps to see if an improvement was made. Less experienced drivers may not feel each change, but the effects of the change may be seen in the lap times.


5) Don't hesitate to experiment:
Each driver has their own preference of how they want their truck to feel. One driver's setup may feel awkward to another driver. There is basically no single 'one' best setup for every driver. Use the Revo tuning guides to better understand what effects each change will make, and then experiment with these changes to better suit your driving style and your particular track condition. It's also beneficial to keep a record of the changes you made and how it affected the truck on the particular track you were driving on.

Important: Some of the following modifications require the use of a rotary power tool for cutting and grinding. Always wear eye protection when using a rotary power tool.
