HPI Racing has added a completely new 1/8th scale truck to its market leading monster truck line up.

The new Hellfire is designed from scratch with only one goal: maximum performance in all conditions! No compromise – the Hellfire is not a converted buggy or tuned up monster truck. It is purpose built to be faster and give better handling than any other competitive truck.

A high level of attention to detail is paid in every area. HPI designers strove to increase performance, to reduce maintenance and to simplify chassis adjustments. The result is a new definition for "performance truck". Optimum Agility and Handling Hellfire features all-new suspension and steering geometries especially designed for best performance with big truck wheels and on rough terrain. A very low centre of gravitygives increased responsiveness and better chassis balance.



Toughest “Basher”
The Savage is HPI’s proven fun “basher” with oversized durability and maximum ground clearance. No Jump too big, no ground too deep, and no stunt too extreme – the Savage tackles it all.
Simply the King of Monster Trucks

Looking for maximum acceleration, agility, speed and handling? Then Hellfire is for you! No Compromise!

Hellfire is extremely light weight and powered by a new more powerful Nitro Star K4.6 HO engine. The new engine is based on the proven HPI Nitro Star K4.6 known from the Savage SS 4.6. The new “High Output” version provides increased horse power and more torque.

Hellfire offers a wide range of tuning adjustments. You can fine tune the truck to every condition or personal driving style. All important suspension parameters are easily adjustable.

Full List of Adjustments:
  • Front inboard toe angle adjustments: 0 degrees to -2 degrees.
  • Rear inboard toe angle adjustments: 2 degrees to 4 degrees.
  • Adjustable front and rear camber using strong steel turnbuckles.
  • The camber can be fine tuned to suit your track conditions.
  • Adjustable steering geometry.
  • Spring clips are included to fine tune your ride height.
  • Anti-dive adjustments: 0 degrees to 2 degrees in 0.5 degree increments.
  • Anti-squat adjustments: 1.5 degrees to 3.5 degrees in 0.5 degree increments.
  • Front kick-up angle: adjustable from 21 to 25 degrees.
  • 24 possible shock positions available to fine tune your suspension.
  • Four different shock pistons are included for a wide range of tuning options.

Hellfire has been designed to allow for easier maintenance with simplified access to all parts. For example only 6 screws have to be removed to access the front or rear diff without dismantling the main chassis or suspension. High quality hex hardware is used throughout to reduce the possibility of stripped screws. All major suspension components are retained or captured without the use of E-clips. Maintenance is simplified and parts are held more securely in place.
