HPI Savage SS 4.6 Kit - Nitro Offroad RC Truck

HPI Savage SS 4.6 Kit
Product Information

New from Raceway is a high performance update to our unassembled Savage SS monster truck, the Savage SS 4.6!

The heart of the Savage SS 4.6 is a completely new 4.6cc (.28 cubic inch) engine that pumps out 2.9 horsepower for a top speed of 44 mph and enough power to do wheelies on command! The powerful K4.6 engine has an anodized billet aluminum head to keep it cool even during extreme off-road driving, true ABC construction using a long-life chromed sleeve, an all-new 8.5mm composite carburetor for high performance and improved high temperature tuning, and a pullstarter for easy starting.

The addition of our dual chamber polished aluminum tuned pipe provides a wide powerband and higher top speed, optimized with revised 47/17 gearing. And, a new dual stage air filter with increased filtering capacity is included to help protect and extend the life of the K4.6 powerplant

To handle the extreme power we’ve added heavy duty parts as standard equipment. Front and rear “4 gear” differentials with updated gears are included for added durability. The entire drivetrain is now equipped with heavy duty diff shafts and cup joints for strength and extended service intervals. High grip Dirt Bonz tires put the power to the ground, and they’re nearly 40% lighter than our standard Savage tires for quicker acceleration. To beef up the braking our dual disc brake kit is standard, featuring two vented stainless steel disc brakes and a machined steel brake hub. Even the steering has been upgraded to an accurate cam-type servo saver, delivering quick steering response and added servo protection.

Since the Savage SS 4.6 is an evolution of the original Savage SS, it includes the features that made the SS so popular. It’s in kit form, not preassembled, so experienced R/C modelers can have the pleasure and satisfaction of building it themselves. Kits also allows owners to build the kit to their exact specifications and customize the truck by adding any option parts such as our Reverse Module, anodized TVP and roll bar sets and Roto Start System during assembly. Since many drivers already have advanced radio systems that are perfect for the Savage SS 4.6, we don't include a radio, which helps lower the price so that we can add high performance hop-up parts and still keep the cost of the truck low. Simply put, kits are fun, convenient and price-conscious.

And, the Savage is one of the toughest R/C monster trucks ever! From the heavy duty TVP chassis design to the massive suspension arms, the Savage SS 4.6 is designed to be driven hard and survive the challenge. And all Savage trucks are supported with a huge assortment of available options parts from HPI and other aftermarket companies, so owners can customize their Savage exactly how they want it. Step up to the speed, power and durability of a Savage SS 4.6!
