Fine-tuning your coilover damping shouldn’t mean stripping out your rear seats or interior panels. On many applications, rear shock adjusters are hidden behind carpet, trim, or seatbacks, making quick adjustments a hassle.
The ECS Rear Damping Extension Kit solves that problem with a clean and functional solution. These flexible extensions relocate the adjustment knobs to an easily accessible point above the rear shock towers, letting you dial in your suspension from inside the cabin, no disassembly required.
Installation is straightforward: simply drill a small access hole in your interior trim and route the extension cables through. The adjustment knobs can be removed to allow the line to pass through smaller openings, minimizing cutting. For proper installation, be sure to fully loosen the set screw, insert the cable, then securely tighten it using the provided Allen key.
Kit Includes:
(2) Rear damping adjuster extension cables
Installation hardware and Allen key
A smart upgrade for track cars, daily drivers, or anyone who values easy access to suspension tuning, without compromising interior fit and finish.
