You want to get the best road balance for everyday use?

Then 5100 STREET TCO SUSPENSION is a perfect option for you.

Maximize grip by controlling rebound and rideheight of your car. These coilovers include springs and are designed to run OEM top mounts. In this set front and rear dampers utilize a coilover design. By choosing this design you prioritize adjustability and the performance of your car. Coilovers which will offer more adjustability for both damping settings and ride height, and typically provide more consistent and predictable handling characteristics.

The initial setup for setting and spring rates is rooted in our extensive development and testing process. Individual preferences can easily be fine-tuned by making adjustments to the rebound knob or altering the ride height. You can adjust the rebound, means you can control the return to extension of your dampers, enabling you to attain the ideal road balance tailored to your specific requirements.

With 12 distinct positions to choose from, each adjustment delivers distinct feedback and a unique driving experience. AST Suspension is a monotube design. This is a benefit for you because these dampers offer a large piston to control the adjustability of rebound damping. There is no aeration or foaming in monotube dampers, this will result in a more responsive valving. AST high pressure dampers offers additional resistance, based on the driving conditions. It will increase performance when you need it.

These dampers are rebuildable, which means that if any damage or issues arise, you can have them addressed at a certified AST service center.

Second handle too high up on leash
Color: Black, Size: Large
Slip lead length provides your reactive dog with too much range to lunge. The second handle is great but it is too high up on the leash. If the slip lead length was shorter and the second handle was lower, this product would be awesome.

Great lead alternative!
Color: Blue, Size: Large
This works great for an alternative to just a slip lead. I work in a kennel and it makes it a lot easier to grip for the dogs that pull a lot.

Won’t stay in place
Color: Blue, Size: Large
While the leash was nicely made, the lead would not stay in place. The slide to hold the “O” ring in place kept sliding there for the leash would loosen. The padded handle was nice for sure
