CTEK Charger Protective Silicone Bumper — Black sleeve for MXS 5.0, MUS 4.3 & CT5 | impact-absorbing, non-abrasive

The CTEK (56-915) Black Bumper is a durable silicone rubber protective sleeve that shields compatible CTEK chargers and vehicle paint from knocks and scratches.

This snug-fitting black bumper is built to fit a range of CTEK battery chargers — including MUS 4.3, Lithium, MXS 5.0, CT5 Time To Go and Powersport models — and acts as a simple, yet effective, barrier between the charger and hard surfaces. Designed specifically for impact absorption and surface protection, the bumper preserves the charger’s finish while reducing the chance of scuffs to painted panels when the unit rests against a vehicle. It slips on easily and stays secure during normal handling and storage.

How does the CTEK Bumper protect my charger and car paint?

The silicone material cushions blows and creates a soft buffer where the charger contacts a vehicle or workshop surface. It prevents direct hard contact that can cause dents, chips or paint transfer, while also reducing vibration during transport.

• Soft high-grade silicone absorbs impact and resists abrasion
• Full-edge coverage prevents chafing against painted surfaces
• Non-abrasive contact minimizes paint marring and scratches

Will this bumper fit my CTEK charger?

This bumper is tailored for several popular CTEK models: MUS 4.3, Lithium, MXS 5.0, CT5 Time To Go and Powersport chargers. It’s molded to match the shape and port locations of those units so you retain full access to connectors and mounting points.

• Model compatibility: MUS 4.3, Lithium, MXS 5.0, CT5 Time To Go, Powersport
• Precision fit preserves charger ergonomics and usability
• Easy on/off fitment for cleaning or replacement

How durable and weather-resistant is the silicone bumper?

The bumper uses high-quality silicone rubber chosen for flexibility and long service life. It resists common workshop oils, light chemicals, and UV exposure better than cheaper plastics, while remaining pliable in cold weather to continue protecting surfaces.

• High-grade silicone resists cracking, tearing and hardening
• Maintains protective properties across temperature changes
• Simple to wipe clean after workshop or garage use

What color options and extras are available?

The standard part (56-915) is offered in black for a discreet, professional look. For a more visible or personalized option, CTEK sells a pink variant separately (Part No. 56-941). There are no electrical or functional modifications to the charger when the bumper is fitted.

• Black model (56-915) for subtle protection

Who is this for: The CTEK Black Bumper is ideal for vehicle owners, garage technicians and powersports enthusiasts who regularly handle battery chargers near painted surfaces. Choose this bumper if you want a simple, durable way to protect both your CTEK charger and vehicle finish from everyday knocks, scrapes, and shop wear without altering charger performance.
