Caster Racing ETO 821 2018 Spec 4wd Off-Road Electric 1/8th Scale Buggy is the updated version including new redesigned hard anodized chassis, updated fully captured CVD axles and loaded with high quality precision cut 7075 T6 aircraft aluminum parts right out of the box. With the advent of powerful brushless motors and LiPo batteries, weight isn't as important as strength in a modern race chassis, so the Caster ETO 821 was designed to be the most durable racing 1/8th scale 4wd buggy on the market. The ETO 821 comes jam packed with pro-race features such as 7075 T6 front and rear shock towers, main chassis plate, motor mount and suspension mounts as the ETO 821 boasts a full roster of upgrade parts right out of the box.

T6 Aircraft Aluminum Chassis:

The ETO 821 features an updated 3mm thick 7075 T6 Aluminum Alloy Chassis precision cut by state of the art CNC machines with fully countersunk screws offering a smooth snag free surface during hard cornering or landings.

Chassis Braces:

ETO 821 includes new 7075 T6 chassis braces both front and rear which provides a stiff chassis with just the right amount of chassis flex.

Motor Mount:

The ETO 821 includes a 7075 T6 2-piece motor mount which places the brushless motor in the ideal position of the buggy, providing balanced weight distribution over the front wheels for maximum steering. The heavy duty 7075 T6 motor mount is designed to dissipate heat from the motor through the mount and through the chassis for maximum cooling.

Steering / Servo Saver:

The ETO 821 features a ball bearing supported cam-style servo saver bell crank system attached to a 7075 T6 aluminum steering link with fixed max-steer ackerman for maximum steering through the entire range of suspension, with minimal bump steer.

Suspension / Shock Towers:

The ETO 821 utilizes thick CNC cut 7075 T6 front and rear shock towers. The precision cut shock towers feature composite roll center inserts and offer easy camber link adjustments.


The shocks on the ETO 821 are large big bore units...bigger is definitely better when it comes to shocks. Hard anodized aluminum threaded shock bodies, shock collars and black anodized aluminum shock caps combined with strong 3.5mm shock shafts provide increased dampening and smooth fluid suspension action. Large diameter pistons are securely held in place by a lock-nut attached to the 3.5mm shock shafts. (various optional easy to identify color coded front and rear shock springs are available separately)

Front / Rear Suspension Arms:

The ETO 821 utilizes durable, oversized lower suspension arms manufactured from strong composite nylon featuring conventional 1/8th scale droop screws which are easily accessed from the top of the vehicle for quick droop adjustments.

Front / Rear Hubs:

The ETO 821 features rear hub carriers with multiple camber link positions while the front pillow ball type suspension hubs allowing for precise steering and an infinite number of camber adjustments combined with oversized steel pillow balls for maximum strength and durability. Aluminum 17mm wheel hexes mated to steel axle stub shafts are used front and rear.

Hinge Pins / Ball Ends:

The ETO 821 features captured ball ends throughout. All steel lower control arm hinge pins are threaded and lock-nutted in place with no e-clips. This increases your chances to finish and win in a long main event.

Gear Differentials / Center Spur Gear:

The ETO 821 includes three heavy duty fluid filled gear differentials with all metal differential gears and lightweight composite diff cases with sealing gaskets and o-rings for leak free diffs.

CVD Driveshafts:

The ETO 821 combines durable and lightweight front, rear and center shafts mated to CVD's throughout that feature hardened steel joints and steel pins. The center driveline is in-line with a zero angle design for maximum durability and efficiency and now feature captured drive pins, making these among the strongest most secure axles around.

Side Mud Guards:

The ETO 821 features removable composite plastic side mud guards that are lightweight and durable. Easily mounted and removed from the chassis in seconds. These mud guards are designed to keep dirt and mud from entering the chassis on loamy or muddy racing surfaces.

*ETO 821 does not include tires,wheels or electronics.
