Upgrade your BMW's suspension with ECS Tuning Adjustable Sway Bar End Links, designed to provide up to 60mm (2.36") of adjustability. These end links allow you to eliminate sway bar preload or fine-tune it for specific racing needs and corner balancing. When installed, they improve drivetrain clearance and enhance sway bar responsiveness by reducing deflection, ensuring superior handling. Perfect for lowered vehicles using springs, coilovers, or air-ride suspension systems, these adjustable sway bar end links allow you to remove unwanted preload caused by changes in the center-to-center distance between sway bar mounting points. By adjusting the end links to a neutral position, you eliminate sway bar preload, enhancing suspension performance in various driving conditions.

The main body of the ECS Sway Bar End Links is crafted from strong, lightweight 6061-T6 billet aluminum and anodized red for superior corrosion resistance. Featuring left and right-hand threaded center sections and machined hex wrench fittings, these end links allow for quick and easy on-the-car adjustments. Zinc-plated hardware ensures secure and lasting adjustments, while the heavy-duty ball joint ends come with weather-resistant rubber boots and stainless steel wire retainers, providing superior protection against salt, rain, and ozone for extended durability. Each kit also includes zinc-plated Nyloc nuts and hardened steel washers for secure installation and improved contact surface on the sway bar.

These end links are designed, engineered, and rigorously tested by ECS Tuning to ensure the highest quality. Whether you have a lowered or stock suspension, these adjustable sway bar end links are the perfect upgrade, offering a high-quality, heavy-duty replacement that fits your specific needs.

Features:

Range of Adjustment: 215mm (8.46") to 275mm (10.82") 6061-T6 Billet Aluminum Construction: Red anodized for superior corrosion resistance Zinc-Plated Hardware: Provides durability and superior corrosion protection Right and Left-Hand Threaded Center Sections: Quick and simple on-the-car adjustments Heavy-Duty Ball Joints(M10x1.5): Weather-resistant rubber boots and stainless steel wire retainers for long-lasting durability

Black anodized billet sway bar end links to replace your flimsy and corroded factory units. Removable hardware for a lifetime serviceable component!

Your factory end link brackets are a one piece design with an integrated stud made of flimsy metal with no coating to protect from the elements. What happens is the end link hardware rusts right to the integrated stud and when you go to remove/replace the end links or brackets they are one strong turn and a snap away from needing to be replaced.

Not only did ECS come up with a stronger solution with a superior resistance to corrosion but went the extra mile to incorporate hardware that can be replaced time and time again so you will never need to replace the brackets themselves. The end link brackets feature chamfers to fit perfectly in factory location and make for a straight forward install. The brackets featuring a slotted area for the bolt head to sit so you don't have the headache of having to get a wrench in the tight space behind the bracket while installing them.

A pair of front end link brackets

A very common weak point on the 3 series BMW is the sheetmetal of the rear shock tower. The sheetmetal here is relatively thin and very susceptible to stress and fatigue. A worn out shock will bottom-out more often and this energy is transferred through the bump stop and into the metal chassis. Stiffer shocks and shock mounts also put more stress on the sheetmetal. Factor in age, mileage, and environmental conditions and it's not a surprise that we see shock tower failures often. BMW addressed this issue with reinforcements of their own but our's are thicker for additional strength. This kit mounts on top of the shock tower and can either be bolted or welded in place. Because of the shape of the rear shock tower, these do not fit cabrio/convertible cars.

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.

BMW has long suffered issues with rear shock mount blowout on M3 and non-M 3 Series models dating back to 1984 with the E30 chassis. Little changed over the following two decades, and E36, E46, and Z3/Z4 models are also prone to this style of failure. After striking a pothole or another seemingly innocuous obstacle, a clunking from the rear emerges and handling becomes sloppy. Your shocks have blown through their mounts. Enter the Ultimate Performance Rear Shock Mount Kit from ECS Tuning. Not only does their industry-first design alleviate the blowout problem once and for all, but allows rear dampers to fully articulate, for the best possible damper performance and longevity. They accomplish this with no noticeable increase in noise, vibration, or harshness (NVH) thanks to their unique rebuildable polyurethane isolation. The poly bushings not only keep NVH to a minimum, but they also reduce impact loading on the bearing, improving bearing life over full solid mounted monoball designs. To further improve bearing life and longevity, this design incorporates a lower dust seal to keep road debris, grit, and other contaminants out of the bearing. These are one of the best rear shock mounts available, and the last you will ever need. Features: Maintenance-free, PTFE lined, stainless steel monoball spherical bearing for full shaft articulation Lower dust seal for improved bearing life 80A polyurethane isolation bushings for NVH control and improved bearing life Accommodates 10mm* Fully constrained shaft mount makes blowouts impossible Hard anodized 6061-T6 construction Class 10 black zinc plated studs New OEM lock nuts included Fully rebuildable design *For use with factory-style 10mm damper shafts. If you have factory-style mounts presently, you have 10mm damper shafts. *During installation a 17ft-lb torque spec is required to avoid damage to the mounts.

Want a race-spec rear shock mount but with the comfort of a factory bushing? This ECS rear shock mount combines the precision and articulation of a spherical bearing with the isolation of urethane bushings. The stainless monoball bearing is lined with PTFE lubricant and suspended in 80A urethane and housed in a hard anodized 6061-T6 aluminum mount. The spherical bearing is a better design than most rear shock mounts because it allows the shock to move and tilt without side-loading the shock shaft (which leads to premature failure of the shock). Most Genuine BMW and aftermarket shock mounts are not designed for shock angles and the stress that track or performance driving will put on the shock shaft. The ECS shock mount is properly designed to handle these loads. The internal bearing is also replaceable - it will be years before you have to replace the entire mount. The ECS mount is fully encapsulated to prevent the common shock mount failure of the stock mount design.

ECS RSM features:

  • Maintenance free, PTFE lined, stainless steel monoball spherical bearing for full shaft articulation
  • 80A polyurethane isolation bushings for NVH control
  • Accommodates 10mm, 12mm, or 14mm damper shafts
  • Fully constrained shaft mount makes RSM blow out impossible
  • Hard anodized 6061-T6 construction
  • Fully rebuildable design

* - the RSM comes with the BMW standard 10mm shock shaft bushings. 12mm is used on some performance shocks and 14mm is used on some true motorsport rear shocks.
