How to Build the Ultimate Stampede in Three Easy Stages
Traxxas #8712 Tool Kit
You can use the tool kit that comes with the Stampede to install all the parts in this article, but upgrading your tools can be just as important as your vehicle modifications. The Traxxas #8712 tool kit includes premium hex bits and nut drivers to perform upgrades or maintenance on your Traxxas model. The kit also includes an overmolded grip and convenient embroidered storage case.
Heavy-Duty Suspension Arms
The super-strong, extra-resilient composite plastic Traxxas developed for the E-Revo VXL, X-Maxx, and Maxx trucks’ suspension parts is now available for the Stampede, Slash and Rustler. The Heavy Duty (HD) arms are even stronger than the Stampede’s stock parts, and the composite formula maintains its flexibility in cold weather. They even come in colors: you can choose blue, orange, green, red, black, or white. Here you can compare the green HD arms with the stock black parts.

Installation is easy: just remove the old arms and replace with the new parts. If you forget which screw goes where, you can consult the Stampede’s exploded views here. Installation takes only a few minutes with just three screws per arm to remove.

Phase 2: Aluminum Options and Servo Upgrade

Superior strength and custom style—that’s what anodized aluminum parts are all about. Traxxas’ precision-machined alloy components are direct replacements for the stock plastic parts and will take our Stampede’s toughness up even higher. We’re going with blue steering blocks, caster blocks, and rear uprights to contrast with the green arms, and we’ll swap the Stampede’s one-piece camber links for adjustable, aluminum turnbuckle links. To exploit all that steering- and suspension-upgrade goodness, the steering servo will be upgraded to the 2075X for digital precision, greater torque, and metal-gear toughness.

The 2075X is a powerful metal-gear servo, delivering 125 oz.-in of torque (over 50% more torque than the stock servo) to steer the Stampede with authority.

Metal gears make this servo extra toughTo remove the stock servo, first turn the truck over and remove the servo-saver, then remove the four screws that secure the servo from the top of the chassis (for clarity, we removed the front suspension in the shot below). Reverse the process to install the 2075X servo.

The Stampede’s stock Ultra Shocks are excellent bump-eaters, but for the ultimate in super-smooth suspension action and extra-long wear, the Big Bore Aluminum Shock set is the way to go. The precision-machined bodies are hard-anodized with slick PTFE-coated bores, and scuff-resistant Titanium Nitride-coated shafts reduce friction on the X-ring seals to the absolute minimum. Progressive-rate springs and silicone shock oil are included, just fill ‘em up and bolt them on.

Phase 3: Velineon Brushless Power-Up

Here’s where we make a giant leap in performance. Upgrading to Velineon brushless power will more than double the Stampede’s speed potential! With the Traxxas Power-Up Program, you can trade in the Stampede’s stock XL-5 speed control and Titan 550 motor for a discount on the Velineon system. You can make the exchange by mail, or at your participating Traxxas dealer—get all the details here.
The Velineon system installs just like the stock speed control and motor. Simply remove the XL-5 and Titan 550 motor, and replace with the VXL-3s and 3500 motor. There are extra holes in the chassis’ electronics platform for the larger VXL-3s speed control. You’ll also need to open up the waterproof receiver box to plug in the speed control and the 2075X servo. The Stampede manual includes instructions on maintaining a watertight seal and plugging in the components, it’s easy. The servo plugs into the Channel 1 port, the speed control plugs into Channel 2, and the plugs only fit one way.

For maximum performance, we’ll replace the Stampede’s 16-tooth pinion and 90-tooth spur gear with a 19-tooth pinion and 86-tooth spur gear, as used by the Stampede VXL. The Velineon system will also work just fine with the stock gearing and your Stampede will still go a lot faster, but not quite as fast as it can go with the VXL gearing.
Stock gearing on the left, VXL gearing on the rightOut of the box, the VXL-3s speed control is set up for use with LiPo batteries with Low Voltage Detection turned on, as confirmed by the green LED when you turn the system on. If you’re using NiMH batteries, switch Low Voltage Detection off by pressing and holding the EZ-Set button until the LED turns from green to red.
