Legendary Off-Road Beast - Boosted Features & Look!

Unleash unstoppable power with the HPI Savage X 4.6 GT-6 — a rugged, high-speed nitro monster built for massive jumps, extreme bashing, and pro-level performance that dominates any terrain.

About the Savage X 4.6 GT-6


Legendary Nitro Monster Power

The HPI Savage X 4.6 GT-6 is driven by the massive Nitro Star F4.6 V2 engine, delivering nearly 3 horsepower and top speeds over 45mph (73kph). With 0.9mm clutch springs and a 2-speed adjustable transmission, it offers explosive acceleration, big-block torque, and precise power delivery for extreme bashing and high-speed thrills.

Ultra-Tough Chassis Design

Built on a 2.5mm thick aluminum Twin Vertical Plate (TVP) chassis, the Savage X 4.6 GT-6 is engineered to survive huge jumps, rough landings, and full-speed crashes. Reinforced bumpers, captured hinge pins, and rugged webbed suspension arms protect the drivetrain and suspension while ensuring durability for serious off-road action.

High-Performance Suspension System

Equipped with oil-filled XL Big Bore shocks, independent double wishbone suspension, and HD spring-loaded servo saver, this monster truck provides smooth damping, precise steering response, and superior control on any terrain. The thick webbed suspension arms absorb impacts while maintaining stability for big-air jumps and aggressive bashing.

Aggressive Wheels & Tires

The Savage X 4.6 GT-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 the Super HD drivetrain and bulletproof 29/9T differentials to the RF-51N Nitro Receiver with low voltage failsafe, this truck is loaded with pro-level upgrades. Pre-cut GT-6 bodyshell with molded details, performance air filter, and durable plastic components enhance scale realism while providing long-lasting performance and visual appeal.
