New from HPI Racing 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
