About this part

Legendary Off-Road Beast - Boosted Features & Look!

Dominate any terrain with the HPI Savage XL 5.9 GTXL-6 — a rugged, high-powered nitro monster built for massive jumps, extreme off-road bashing, and pro-level performance straight out of the box.

About the Savage XL 5.9 GTXL-6


Massive 5.9cc Engine

The HPI Savage XL 5.9 GTXL-6 is powered by the Nitro Star F5.9 engine, delivering enormous torque and top-end speed for extreme off-road performance. With a 3-shoe aluminum clutch, vented clutch bell, and Rotostart 3 system, it transfers power efficiently while offering easy starting and long-lasting durability.

Ultra-Tough Chassis Design

Built on a 3.0mm thick Twin Vertical Plate (TVP) chassis with reinforced motor plates, the Savage XL 5.9 handles massive jumps, rough landings, and full-speed crashes. Captured hinge pins, rugged bumpers, and roll hoop protect critical components while maintaining stability across challenging terrain.

Advanced Suspension System

Equipped with oil-filled XL Big Bore shocks, independent double wishbone suspension, and heavy-duty HD servo saver, this truck offers smooth damping, precise steering, and control for high-speed bashing. Super-thick webbed suspension arms absorb impacts and keep the truck stable on any surface

High-Performance Drivetrain

The Savage XL 5.9 GTXL-6 comes with 3.8" Havok wheels and Tredz HD Terrahex tires for maximum grip, responsive handling, and all-terrain performance. Standardized 17mm aluminum hex hubs make it compatible with a wide range of 1/8-scale wheels and tires, giving enthusiasts flexibility for upgrades or replacements.

Pro-Level Performance Features

From pre-cut factory-painted GTXL-6 body and molded detail parts to dual-stage air filter, enclosed radio box, and RF-51N Nitro Receiver with low-voltage failsafe, this truck is loaded with pro-level upgrades.

I mean.. it’s a brand new Savage XL! What more could you want? I will say the servos in this truck are insane. Both the steering and throttle servos have plenty of speed and power. The built in pre programmed failsafe is also an added plus. This truck is a beast.. you won’t regret it!

Garbage product! Don’t buy HPI products!! Tons of issues and poor quality control and poor assembly by HPI. No support from HPI or Amain. Out of the box the servo was dead, off/on switch didn’t work, I completed the break in and tuning, truck won’t shift! I reached out to HPI Racing via email, they told me that I’d have to go thru the Distributor to get support because they offer no support, (additionally I found out that they’re headquartered in Denmark?! ) it says it on their webpage, there was no where I could send the truck to? Screw HPI! Just back and forth and a lot of run around between Amain and HPI. Now I just have a $750 paperweight. I feel like I just got scammed out of $755.00
