HPI RTR SAVAGE X 4.6 with NITRO GT-2 TRUCK BODY The RTR Savage X 4.6 is our fastest and strongest ready-to-run Savage… EVER! That's right, we've raised the bar by adding a massive F4.6 engine and beefed up the chassis and drivetrain to handle the power. The result is a truck that has enough Big Block power to do wheelies on command with a scorching top speed of more than 45 MPH. A huge list of performance and durability upgrades come standard in the RTR Savage X 4.6, so you know that you've got a truck that can handle extreme off-road driving. Included with the Savage X 4.6 are two of our latest option parts: #86827 Alloy Diff Cases and new stronger brake disks! The Alloy Diff Cases prevent damage to the internal diff gears, even with the power of a Big Block engine. The result is more driving and less maintenance! New dual disk brakes provide more stopping power and are more fade-resistant than ever! Savage X 4.6 Durability Eight long coil-over shocks absorb any type of rough terrain you can throw at the RTR Savage X 4.6, and beefy suspension arms and uprights can take the punishment of big-air drops and top speed runs over bumpy terrain. Keeping everything protected is the reinforced "X" TVP chassis, which features a custom 'X' graphic. Structural webbing and extra screws have been added to the central gearbox to improve durability, and add stiffness. Extra material was added to the skid plates and bumper to help the Savage X 4.6 survive huge jumps and crashes. The engine mount and engine plate are now thicker to give you more durability and endurance, especially when you're landing massive jumps!
