No Revalves Necessary
The ultra wide range of adjustment offered by the CFD piston allows for the convenience of tuning your suspension without having to revalve your dampers. A conventional shock absorber can withstand a 2kg spring rate difference before requiring a revalve, whereas the Concave Flow Digressive Technology has a broad range of 8kg spring rates. This is invaluable for tuning your suspension quickly at the track on race day.
Jekyll and Hyde
The Concave Flow Digressive Piston allows for a Jekyll and Hyde personality. Lower spring rates can be stiffened up by using the wide damping range as an artificial spring rate, while higher spring rates feel much smoother. The large adjustment range contributes to a comfortable ride on the street and unyielding performance on the track, all with the twist of a single adjustment knob.
520 Series Coilovers are custom, hand-built to order. Most applications have a 4-7 week lead time. Lead times for certain applications and peak season orders may vary.

Earth Animal Treats
Flavor Name: Peanut Butter, Size: 20 Count (Pack of 1)
This is a great product, I first learned about this product when I took my dog to a training sesion. The instructor was using them as a training tool and my dog really got attached to them as I kept using them at home. She has been hooked on them ever sence. We give them to her now when she has been a good dog around the house.

Long lasting dog chew!
Flavor Name: Peanut Butter, Size: 20 Count (Pack of 1)
Mini Dachshund loves these! We tried many varieties of chews but most don’t last more than a min or two. So happy with these -finally a long lasting chew to give her when she needs something to occupy her in the evening. So far no stomach issues with these, and no obvious weird smell. Have not noticed any mess (as one person stated) they seem like a clean treat for our pup. Will buy again.

Best treat for puppy
My vet and puppy’s trainer recommend this treat for my puppy. Much better than rawhide bones for digestion. My puppy loves the flavored sticks. Peanut butter is her favorite. She gets very excited when I pull out treat. She takes stick and runs to her “place” to chew. Stops desire to chew on furniture, etc. I buy several packages at a time because she loves them and I love quiet down time.

Not long lasting but my dog loves them
Flavor Name: Peanut Butter, Size: 20 Count (Pack of 1)
My little dog loves them. But they are NOT long lasting and definitely require supervision. Would love to find a product that would last longer than ten minutes,

Good Quality Chew for Dogs with Sensitive Stomachs
Flavor Name: Peanut Butter, Size: 40 Count (Pack of 1)
I have a small dog with a sensitive stomach and these sticks are perfect for him. It's a low calorie treat that takes him 10-15 minutes to eat and he really likes the peanut butter taste. These are not cheap but by purchasing them in the 40-pack box it's a little less expensive than the smaller 10 pack bags. I know there are cheaper brands for this type of chew stick, but I like that this product is made in the US and so I don't worry as much about poor manufacturing practices or unknown additives.
