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

Then 5100 STREET NON INVERTED 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. This AST design incorporates coilovers for the front dampers and maintains for the rear dampers the OEM setup. This translates to a more comfortable configuration that achieves a flawless road balance. Consider this kit features, vehicle specific, fixed spring rates for the rears.

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 will increase performance, when you need it, in various driving conditions.

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

Good luck
So far so good,fit perfectly but was a real bitch to replace on a 09 Crv. Tried from underneath but couldn’t get to the rear bolt, so I had to go from the top. Poor engineering on Hondas part.

Don't waste your money.
Instead of buying one from the local auto store, thought I'd save money and get this. Bad choice. Installed it and it didn't work. Took it to the auto shop to be tested and they said it didn't work. Cheap imitation of the the real thing.
