This is the Pro-Line ProTrac Rear Suspension Arm Set, and is intended for use with the Pro-Line ProTrac Suspension Kit for the Traxxas Slash Short Course Truck. Pro-Line's new ProTrac™ Suspension kit for Slash® is one easy to install kit that greatly increases forward acceleration, corner speed, consistency and drivability. The critics are ranting and raving about ProTrac™.

RC Car Action Magazine:  "It all comes down to the numbers. According to the stopwatch, my laps were about 1 ½ to 2 seconds faster with the Pro-Line suspension system.”

Xtreme R/C Car Magazine: “The result is almost staggering after my test down at OCRC Raceway. We can’t recommend this kit enough.”

Why ProTrac™ ?
Faster, more consistent laps
Increased Forward Acceleration
More Fluid Suspension Geometry for Jumping
Light Weight/Race Inspired Design
Increased Tunability
Double Jump Durability

Really a quality part but don't be fooled like I did and order them thinking they are a replacement for the stock arms! Looking forward to making the kit complete!

Pro-Line ProTrac Rear Suspension Arm Set
Those arms have the same toe in as stock Slash 2wd but combined with the length of the stock Rustler. The result? A better handling and a greater durability. Suitable for 2WD Slash and Rustler/Stampede.
