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.

Arnotts air suspension solenoid valve block is a direct replacement for the vehicle's failing valve block. The Arnott solenoid valve block is made from the highest quality materials, including O-rings and electrical components, and is designed to meet or exceed the original equipment. An air suspension solenoid valve block is responsible for distributing air from the compressor to your air struts or air springs. Over time, valve block O-rings can dry rot and leak air, causing your compressor to overwork or allow moisture to degrade the electrical solenoid components causing additional problems.
