The Savage XL is the extra-large, extra-tough and extra-powerful big brother to the Savage X monster truck. For improved stability and handling, the Savage XL has a 55mm longer wheelbase and a 25mm wider track. With a longer wheelbase, wider stance and huge 5.9cc (.36 cubic inch) engine, the Savage XL is ready to rock and roll right out of the box. The HPI design team added strategically strengthened hop-up parts to tame the massive K5.9 power for unmatched durability. The Savage XL soaks up the rough stuff with ease because it's the biggest, toughest, and most powerful Savage ever!

The Savage XL definitely looks the part of the massive monster truck! The extended wheelbase is the perfect evolution of the Savage design, and the extended chassis and larger tires are a perfect match for the new, bigger 'GT Gigante' body! The wide front grill and huge headlights of the GT Gigante body merge with the flared wheel arches front and rear for a huge 'wow factor,' adding to the impression of huge size and strength! The large Terra Pin tires fit the body perfectly for a scale monster truck look that's sure to intimidate the opposition at your local bashing arena! But the Savage XL isn't about just looking great, the HPI designers went all-out to make sure it performs as good as it looks! Bigger in every dimension than the standard Savage X, the Savage XL is longer, wider, taller, more ground clearance and tires that are nearly 7" in diameter! It's based on the practically indestructible Savage X chassis and features durability upgrades like thicker 3mm TVP chassis plates, 3mm alloy engine plate, machine-cut steel differential rings and pinion bevel gears, steel spur gear, heavy-duty clutchbell, extra heavy-duty dogbones, larger diff out drives, machined brake hub, dual fiber disk brakes and much more!

HPI makes it as easy for beginners to get into Nitro RC. The Savage XL RTR it is completely pre-built and ready to go right out of the box! HPI Ready-To-Run models bring you the same high performance and quality that you expect from racing kits with the added convenience of being factory pre-assembled to the highest standards. Everything is assembled and tuned for you by professionals - radio system, diffs, slipper clutch, shocks and more are perfect before you even open the box! Just a few steps are needed to get your car up and running, such as adding the batteries to the transmitter and breaking in the engine - which is now even easier with our comprehensive manual.
