![]() ![]() With the stock pistons and P2 rockers, 50wt to 65wt fluid is a good starting point. On smooth tracks with a lot of bite, the damping should be increased for better response. Keep this in mind when selecting the right fluid for your conditions. Hotter days will make the fluid feel a little thinner, so on very hot days, you may need to step up 5wt to 10wt in the dampers for more desirable performance. Ambient temperatures also affect damping fluids. This will loosen the damping up a bit after the truck has made a lap or two around the track. The fluid inside of the Revo's dampers gets a little warmer than with dampers found on traditional suspension systems, due to the extra work they perform. These are base settings and may need to change due to varying track conditions. P3 rockers work well with 40wt shock oil. For P1 rockers start with 60wt shock oil. My base shock oil choice for the P2 rocker set is around 50wt for most tracks, using the stock piston arrangement. The #3 piston is more suited for heavier springs such as the springs designed for the long travel set-up. Out of the box, the stock GTR shocks come assembled with #1 pistons in the front and #2 piston in the rear. Smaller holes provide more damping (slower action). Each one with different hole sizes, piston #1 = large, piston #2 = medium, piston #3 = small. All three are made with two bypass holes. There are three pistons available for the GTR shocks. Wipe away the excess oil, and it's ready. Spread a little bit of oil around the edge of the shock bladder, then thread on the cap slowly while the excess oil seeps out of the bleed hole. Check to make sure the shock bladder is seated correctly into the cap. Next, slowly move the piston up and down to clear all bubbles. Just fill up the shock body close to the top. Shock Tuning w/ Fluids and Pistonsįilling the shocks with oil - With the bleed hole molded into the cap, anyone can build a perfect shock every time. ![]() The PTFE?-coated hard-anodized dampers ( above #5460X) are even smoother and have TiN (Titanium Nitride) coated shafts to resist wear. Also, the use of just one x-ring allows for more room for stroke since it takes up less space than a traditional two o-ring set-up found in most shocks today. X-rings provide two sealing surfaces against the shaft vs. They also come standard with x-rings for a perfect seal and smooth action. They are very smooth and are equipped with threaded bodies to make pre-load adjustments a snap. The stock aluminum GTR shock absorbers on the Revo work extremely well. I'll explain what components I use for track racing along with what adjustments I make for different conditions. Each rocker set is designed with different geometries to raise or lower the progressive rate of the suspension. This means that the suspension will get stiffer as it is compressed. The 90mm travel rockers were designed to increase the progressive rate felt at the wheel as the suspension is compressed. The geometries designed into the Revo's rocker arms change the way the shock feels as the suspension is compressed. The Revo's suspension system is very unique and offers independent tuning options that most standard-styled suspension systems cannot. The Revo is an excellent track performer right out of the box, and with the many trick factory accessories available, you can custom tailor and personalize your Revo to be the ultimate race machine. Some are for strengthening, and some are for lightening different areas of the truck (some do both). However, each accessory component does have its own purpose and offers an increase in performance in one way or another. Keep in mind, even though many accessories are mentioned for the Revo, they are not all necessary for competitive track racing. The format of this guide will be similar to the Maxx series of articles where I separated the guide into three categories: suspension, chassis, and transmission/drivetrain. ![]() So as promised, here is the first installment of the complete performance-tuning guide for the Revo. It's time to let all of you race hungry Revo owners in on everything I've learned about this killer truck. Now, after all this testing and track time, I've put together a comprehensive, highly informative, and accurate set-up guide. I've put the Revo to the test on many different styles of tracks, with conditions ranging from hard packed blue groove to soft and loamy. After tons of testing and many weekends at the track racing the new Revo, I've come to know our new monster pretty well.
