HPI 160550 1/8 Savage XL Nitro SBK 4WD Monster Truck Builders Kit

Build Your Own Original,
Authentic HPI Savage XL!
The Savage XL SBK Monster Truck Kit is designed for enthusiasts who want the full hands on experience of building an original and authentic HPI Savage XL from the ground up. This self build kit delivers the satisfaction of assembling one of the most iconic nitro monster trucks ever created while providing a proven and extremely durable platform that is ready for serious off road action once complete. With its extra long TVP chassis, extra long wheelbase and extra large stance, the Savage XL is built to rock and roll over virtually any kind of terrain with confidence and control.

As a true self build kit, the Savage XL SBK is supplied without engine or electronics, allowing builders to choose their preferred nitro power plant, radio system and servos. This makes the kit ideal for experienced hobbyists who want full control over performance, tuning and final setup. Clear and detailed assembly instructions guide you through every stage of the build process, with exploded diagrams and part references that ensure construction is both enjoyable and rewarding.

The Savage XL SBK includes all the same core features that make the Savage XL 5.9 GTXL 6 legendary. The SBK version also benefits from new performance focused upgrades, including steel second and third gear components for the 3-speed transmission, new hex hardware throughout and precision machined 29/9T differential gears. These additions enhance strength, longevity and drivetrain efficiency, making the Savage XL SBK even more capable of handling high power nitro engines.

Once completed with your choice of engine and electronics, the Savage XL SBK Monster Truck delivers the sound, performance and unmistakable presence that only a nitro powered monster truck can provide. It is the perfect choice for builders who enjoy the process as much as the driving and want a strong, upgrade ready platform that can grow with their skills and ambitions.

 
 
Legendary TVP Chassis Strength
At the heart of the SBK kit is a strong twin vertical plate chassis that delivers outstanding rigidity and durability. This proven design is built to handle powerful nitro engines and aggressive driving while keeping the vehicle balanced and protected. Key components are shielded within the chassis layout to help maintain reliability during hard landings, high speed runs and demanding off road conditions.

The Savage started the RC bashing movement and, two decades later, it remains stronger than ever. HPI Racing is proud to bring this legend back into the ring with the holy grail of monster trucks, the jewel in the crown of the Savage legacy.

Delivering excellent agility and precise handling, this wheel and tire combination provides the grip and control needed to dominate a wide range of off-road surfaces.

 

 
 
 
 
BIG BORE NYLON SHOCKS
Four huge XL-size Big Bore shocks give all the suspension action you need to get out and blast through the roughest of tracks or off-road terrain. With slick nylon bodies they are lightweight and strong, with almost no friction 'stiction' between the shock piston and shock body. The extra-large capacity gives you extra control and damping action so you have the driving feel that makes off-road driving so much fun!

 

HD SPRING-LOADED SERVO SAVER
Continuing the Savage's reinforcements, we're using even more HD upgrades in the standard spec! This heavy-duty servo saver spring provides more direct steering for all the new Savage X Nitro and Flux models, allowing today's stronger steering servos to give the Savage faster and more immediate steering response.

 
TOUGH SAVAGE SUSPENSION
After almost 2 decades of seriously thrilling RC bashing performance, the HPI Savage has earned a reputation for being the toughest monster truck you can find. The Savage suspension has evolved along the way as well. The Savage XL SBK features the latest ultra-tough, super-thick webbed suspension arms and uprights that can take a barrage of abuse and punishment, giving you plenty of big-air thrills in their stride.

DUAL BRAKE DISCS
Stopping this beast like a pro you'll need to dab the anchor in the turns or to scrub speed whilst flying through the air and hit the right combination of throttle and brake to set your pitch right for that perfect landing... These twin vented disk brakes are made from heat-resistant fiber material delivering shorter brake distances, reduced brake fade from heat build-up and overall better performance on the track!

CAPTURED HINGE PINS
It's not just about ballistic action, the new generation of Savages also have usability high on their agenda...  Over the years Savage fans around the world have told us the hinge pins need to be secured in place so they don't come loose during extreme bashing, well our designers are always listening and have fitted the car with hinge pin covers to ensure they don't go anywhere, no matter how hard you bash

 
RUGGED BUMPERS FRONT AND REAR
With a chunkier, more aggressive than ever look, the new front and rear bumpers also have space for both 5mm and 3mm LEDs so you can add your choice of lights and light up the track while you bash

LEGENDARY ALUMINUM TWIN VERTICAL PLATE CHASSIS
The beefy metal plates that house all the good stuff under the hood are synonymous with the Savage family. The 3.0mm thick "TVP" as we call them - are unshakeably strong, yet lightweight and provide the ultimate backbone built to handle gigantic jumps, rough landings, rolls and full-speed crashes.

17MM HEX HUBS
For the new generation of Savages we've introduced Standardized 17mm Aluminum Hex Hubs. This means your Savage truck is ready to use any of the gigantic range of 1/8th scale buggy and truggy wheels and tires available from HPI. A large, black, serrated 17mm nut holds the wheel securely to the hub for worry-free bashing duties. 

 
MOLDED BODY COMPONENTS
Our best-ever generation of Savage upgrades are not just limited to performance, the brand new HPI designed GTXL-6 body also looks awesome in any livery and plastic molded body detail parts including realistic grille, vents, mirrors and roll bars

 
PERFORMANCE AIR FILTER
Included in the SBK and vital for air supply along with protection against dust and dirt is a performance airfilter. The design features two different foams for two-level protection. While the large air intake is right in the middle of the foam cylinder with two solid nylon plates at the top and bottom helps prevent damage inside your engine. The large dimensions of the filter element and air intake give optimal, constant air supply and maximum performance

Proven 3 Speed Transmission with NEW Steel Gears
The Savage XL features the legendary Savage three speed transmission, designed to get the most out of your big block nitro engine of choice. 

The Savage XL SBK is upgraded with new steel second and third speed gears, engineered for increased strength and durability under high power conditions. The redesigned second gear provides easy access to the clutch adjustment, allowing fine tuning without the need to disassemble the transmission.

The transmission is fully adjustable, giving you complete control over shift points so you can choose exactly how early or late the Savage XL moves into higher gears. This allows you to tune the driving character of the truck to match your engine setup, terrain and driving style.

3-SHOE ALUMINUM CLUTCH
The Savage XL SBK includes the latest XL-tough 3-shoe aluminum clutch to get the power from your choice of engine into the drivetrain. Using a unique blend of aluminum, the clutch shoes will resist wear, not be affected by engine heat and last for a very long time. There's no more secure way to get the power to the ground!

UlTIMATE SAVAGE TOUGHNESS
From the Super HD Drivetrain, to the Bulletproof 29/9T Differentials, to the new Rugged Bumpers, every inch of the Savage XL SBK is built to survive and dominate. With beefy suspension arms, ready to take the punishment of big-air drops while everything within is protected by the reinforced thick aluminum TVP (Twin Vertical Plate) chassis, emblazoned with the notorious 'XL' emblem.
