RCcarStars Traxxas Slash 4wd Service Techs
Slash Upgrade Service Performance Parts
Xpert Metal Gear Servo for Traxxas Slash Upgrade
Xpert RC All Metal Gear Servo - Included In Performance Package for Traxxas Slash 4x4
Traxxas Slash 4wd Upgrades Service
RCcarStars now offers those of you who want to add some Performance Upgrades to your Traxxas Slash 4x4 via our "Stage 1 Performance Upgrade Package".  The Traxxas Slash out of the box, is pretty-darn durable and will take a lot of abuse.  But there are areas on the Slash that are weak points. We have identified some of the major areas that could use some improvement on the Slash 4wd RC.   And our Stage-One kit is ideal for those of you who are running 2-cell batteries but want more performance with the added "BLING Factor" of aluminum upgrade parts.  

Our Performance Upgrade Package is for all Slash 4x4 models and features a "total upgrade of the steering and suspension" for major improved handeling and duabilty.  No more major slop-in your steering. as we upgrade the front and rear hubs to ST Racing Concepts aluminum steering knuckles and rear hubs,  We also upgrade the steering rack (AKA - Bellcrank) to give you a more sensitive feel steering with the new Xpert RC servo thats included in the upgrade package. The servo has double the torque of the stock Traxxas servo and it's almost twice as fast.  Best of all the servo is brushless and has all metal gears!!!


No Performance Package would be complete if you don't have traction for all that power the Slash puts to the ground.  You will quickly find out that the "Stock Traxxas Tires are great for the asphalt but really lack traction in the dirt!!  And since we are upgrading all the steering and key suspension parts, we are including a new set of Duratrax Lockup SC tires and wheels in the c2 tire compound.  You will find this tire is not only affordable but really works well in hard pack, and loose dirt, grass and more. 

Our Traxxas Slash package also includes more services and parts upgrades that you will find listed below.  We are always more than happy to discuss the performance upgrades package in addition
 to recommend other proven hop-ups for those of you who may be running 3cell batteries most of the time.  When you run 3 cell batteries you may have to add additional upgrades to achieve your desired results in speed, handling and durability.  

​If the parts are in stock it's a one to two day turn around for the work.  Please call to schedule an appointment or for a quote should you want to add some additional upgrades like shocks, driveshafts and more!
