Our designers wanted to make sure the Savage X 4.6 drivetrain could handle the extra power of the Nitro Star F4.6. The Savage drivetrain features a permanent 4WD system and spins on rubber-sealed ball bearings. The proven 2 speed transmission uses tough metal gears for durability, and has adjustable shift points for the ultimate tuning. To add extra strength, aluminum alloy diff cases are standard on the front and rear differentials, pre-installed and shimmed to extend the maintenance interval of the HPI 4-gear differential. The adjustable slipper clutch features a durable slipper pad, so there's less maintenance and more driving! Finally, to make sure you can stop this beast quickly, the Savage X 4.6 is equipped with a twin vented disk brake made from heat-resistant fiber material to give you more stopping power!

HPI makes it as easy as possible to get into RC Off-Road action. The Savage X 4.6 is completely pre-built and ready to go right out of the box! Everything is assembled and tuned for you by professionals - diffs, shocks, suspension and more are perfect before you even open the package. And with many of the top Savage options already installed, you don't have to do a thing to get going fast!

HPI Ready-To-Run vehicles bring you the same high performance and quality that you'd expect from a high end RC kit but with the added convenience of being factory pre-assembled to the highest standards - giving you a high performance RC truck straight from the box!

As with all HPI cars and trucks, you get a full, in-depth instruction manual with step-by-step instructions that allow you to easily disassemble and reassemble your truck for maintenance and easy servicing. The manual also includes a handy parts list and full-scale drawings of the parts and hardware. And the included HPI RC Car DVD is your personal RC car expert in a box!

Head to any track and it's easy to see the HPI Savage is the most popular monster truck around. With unrivaled backing in the form of toll-free HPI customer service, knowledgeable hobby shop staff, fanatical owners, outstanding online support, plus a huge racing scene, the Savage is not only the most popular big-block monster truck around, it's the best supported!

In addition to personal and friendly advice from tuners, racers and shop staff, a huge range of option parts are available from HPI and a massive assortment of other aftermarket manufacturers! Choose from anodized aluminum parts in a rainbow of colors, pure racing options like lowered chassis plates, big horsepower upgrades like giant engines, durability options to handle the extra power, functional add-ons like HPI's illuminated battery level indicator, plus pure 'bling' bolt-ons like sweet custom chrome wheels and funky treaded tires!

When normal 4WD can't cut it, when delicate racing parts fail, or when the terrain is simply too terrifying for pure-bred race vehicles, that's when the Big Block 1/8 scale Savage X 4.6 is in its element! Engineered for the most brutal of environments and built for durability in the most extreme terrain, the Savage X 4.6 is the ultimate 'basher' monster truck!

Fat, chunky treads on each wheel grip any type of terrain, whether wet or dry, mud or asphalt. The full-time 4WD drivetrain pulls the truck over and through anything in its path. Four Big Bore coil-over shocks absorb huge drops and help give extra traction on rough surfaces.

With all of this power and durability, the jumping ability of the Savage X 4.6 is unsurpassed by any other monster truck. With a top speed of over 45 MPH, hitting a ramp with something this size must be seen to be believed! Back flips, forward flips, double back flips and more stunts are easy with this much power and control! Landing the truck is easy with Big Bore shocks to absorb the landings and tough suspension parts that take the abuse of jumping with ease.

Combine all of this with the massive horsepower of the Big Block F4.6 engine and you get the roughest, toughest truck around!
