Vaterra K-5 Blazer Ascender Features

Vaterra K-5 Blazer Ascender 2

Vaterra’s 1986 Chevrolet K-5 Blazer Ascender is made for those who are into rock climbing, scale realism, and for those who love building their own kits.

The Vaterra K-5 Blazer Ascender 1/10 scale 4WD vehicle comes with the 1986 Chevrolet K-5 Blazer body that comes clear to allow you to add on your own paint job. The Vaterra Ascender chassis features stamped-steel ladder frames with adjustable wheelbase, a metal gear transmission and great off-road suspensions. It was also really cool that the Vaterra K-5 Blazer Ascender’s grill is made of plastic.

The stamped steel ladder frame chassis and suspension allow for changes to the wheelbase that will let you switch around the bodies to change how the truck performs. The thickness of the front rails are slightly smaller than the ones used in the rear, allowing the front to slide into the rear.

The front end suspension features a 3-link setup with a panhard bar, while the rear suspension is the standard 4-link.

You can get lots of steering out of the hubs on the front axle, and the Vaterra K-5 Blazer Ascender probably has the most steering throw for the 1/10-scale trail truck class.

The ride height is pretty high and gives you lots of clearance, which is going to help you get over those rocks.

The licensed Interco TSL SX Super Swamper tires come with foam inserts and are pretty hard and sticky. The wheels are chrome plated and the tires are glued to them.

As a kit, you would need to puchase the motor, ESC, battery, steering servo, and receiver separately.

Vaterra K-5 Blazer Ascender Review

Vaterra K-5 Blazer Ascender 3


One of my favorite things about the Vaterra K-5 Blazer Ascender is how amazing the steering is. As mentioned earlier, this crawler has the most steering throw for the 1/10-scale trail truck class. No other stock 1/10 scale crawler has ever come with such a wide steering angle, and this makes a huge difference out on the trail or when you are out competing as having to back up to make a turn counts against you.

On-road, the super low center of gravity ensures that the truck does not traction roll on pavement, much to our surprise since it has such a large amount of steering. Perhaps it could go over with a faster motor or use of the 2 speed transmission, but it was hard getting the truck to flip.


Jumping off ramps would depend on the motor and the ESC you choose. Overall, the aluminum links and chassis mounted bumpers ensured that the truck stayed intact after each jump.


This is a crawler made for overcoming the rocks. It absorbs bumps very well thanks to its oil filled shocks and a 4 link in the rear.


We broke some parts and found some weak points but in general, the Vaterra K-5 Blazer Ascender is pretty durable. The ring and pinion in the axles, as well as the driveshafts, are considered the weakest points of the truck. We ended up breaking all three parts, although replacement parts were easily available.

Aftermarket and Support

This would depend on where you live, but we were able to buy parts for this kit in our local hobby shop and on Amazon.


The Vaterra’s 1986 Chevrolet K-5 Blazer Ascender looks great and we truly enjoy driving this truck. If you want a truck for crawling that looks good and functions like the real deal, then this truck will not disappoint.
