EDFC ACTIVE PRO is a high-spec version of EDFC ACTIVE, which enables automatic adjustment of damping force according to the changes in longitudinal G-force and vehicle speed, and comes with new and upgraded functions.Newly-added features, such as individual adjustment of 4 shock absorbers, lateral (cornering) G-actuated automatic adjustment, vehicle speed pulse input and 2 additional input ports to communicate with drivers, are sure to bring out the full potential of each shock absorber as well as the vehicle itself. Please enjoy another dimension of shock absorber performance that EDFC ACTIVE PRO brings. (Patent Pending).
*Four-Wheel Independent Adjustment*
EDFC ACTIVE adjusts front and rear damping force separately, but left and right simultaneously. With EDFC ACTIVE PRO, damping force for all 4 suspensions can be adjusted separately. This enables finer adjustment according to the road layout and conditions. This feature also works with automatic adjustment.
*Lateral G-Actuated Adjustment*
While EDFC ACTIVE enables automatic adjustments based on changes in acceleration/deceleration (longitudinal) G-force and vehicle speed, EDFC ACTIVE PRO adds the capability to adjust to lateral (cornering) G-force change. This feature offers the advantages of ability to suppress side rolls, to balance distribution of left/right cornering loads and/or to increase cornering speed. In addition, understeering/oversteering can be controlled by adjusting front/rear damping force separately.
This lateral G-actuated adjustment can be combined with longitudinal G-actuated adjustment for a full 360-degree adjustment and/or with speed-sensitive adjustment for most comprehensive adjustment.
This is useful not only for improving times on tracks/circuits and drivability, but also for daily driving as stable cornering can probably have positive effects on reducing burden on drivers and on minimizing tire abrasion.
*External Input for Vehicle's Speed Pulse*
In addition to the vehicle speed calculated by the use of optional GPS kit, EDFC ACTIVE PRO can adjust damping force according to the vehicle speed signal data obtained via external input port. This enables uninterrupted speed-sensitive adjustment even when/where GPS signal is not available.
It is required to know the type of speed pulse because it varies quite a bit by vehicle models, but EDFC ACTIVE PRO can be programmed easily without such details. To set up, nothing other than the controller is needed.
Acquisition of speed signal might not be possible with some vehicle models. In such case, the speed-sensitive adjustment is only available with optional GPS kit used.
*2 Additional Input Ports for External Signals*
EDFC ACTIVE brought the automatic damping force adjustment into reality, but there are customers asking more.
"I want to have more control over the car."
"I want to give my own cue, independent of G-force and speed change."
EDFC ACTIVE PRO comes with 2 external input ports in order to meet such needs. While the signal is on, the damping force is adjusted to and stays at the preset level.
For example, it can be connected to the parking brake signal for better drifting, to a universal switch to turn it on when the driver sees the slippery surface, and so on. Each and every driver can use these ports as he/she likes, for wider varieties of purposes.

Border Collie Approved: Easy to Clean, Durable, and Great Bounce
Size: Medium (2.5"), Style: Fetch Pack 2
These are the best balls out there for dogs. These fit great in the chuck-it ball launcher, which we need to wear out my border collie. They fit her mouth properly and, most importantly, do not absorb all the spit or water after a good rain. They are quick to clean off and have good weight so you can let them fly! Furthermore, they bounce well, which is perfect for my dog that likes to catch them on a bounce. The ball is a strong rubber, so should not be easy to chew up. I've used these for years, and the only time I've had to replace them is when one gets lost in the hay field. I highly suggest these as replacements for the common tennis balls.

Treats and plenty of ball throwing with these doggie toy
Size: Medium (2.5"), Style: Fetch Pack 1
I have actually purchased these twice already. I love the one that glows in the dark but it still got lost in my yard lol. My dog is a big breed half pitt/Labrador so she did chew through one of them already. I play ball with her every single day but I DO have to take them away from her because she will destroy them. They are great to add in treats as well, that was one of the my favorite things about them as well. They do last just if you have an over zealous chewer do not let them keep them for long periods of time. They are a good value for the price. Buy them your dog will love it!

My Female GSD loves
Size: Medium (2.5"), Style: Fetch Pack 1, Size: Medium (2.5"), Style: Fetch Pack 1
Shasta is my smallest. Six in December (2025) along with her brother. Sheβs 100 lbs and outside, completely ball driven see last picture. Donβt let the size (2.5β) of these Chuck-It balls deter you. If your larger Breed dog has any orthopedic issues, has already torn their ACL etc, one has arthritis but wants to play. This size is perfect!
Shazzy was born with several ortho issues. I donβt throw balls distance but right to her. This size and lighter weight assure even when Shazzy is spazzy w excitement, sheβll catch the ball mid air.
The green balls are softer, and glow in the dark. In summer we can play well past dusk and I can see them!
Her personality shows in the pictures. Playing ball is part of her. These balls are just perfect for her situation. Somehow they disappear, she loves making baskets, puts them in my tractor bucket, or my gardening bucket..then get put in burn pile, trash etc. I keep replacing them because sheβd look day and night if we actually ran out!! πβοΈππΌππΌ

Holds up pretty well.
Color: Green Helix, Size: Medium
Holds up against my velociraptor! Much better than some of the other holey balls that get torn apart quickly. I think this is a great idea to reuse old shoe soles into toys for the heavy chewers like heelers. I would like to see a large ball like 10-12 inch diameter, so they can push and throw it around.
