As a critical component in the rear suspension system of 2017-2023
Tesla Model 3/Model Y, this premium brand-grade rear coil spring dumper upper isolator pad cover is engineered to
match original factory specifications. Its core functions focus on
"vibration isolation + spring & chassis protection + noise
reduction":
- Suspension Vibration Isolation: Acting as a buffer between the rear coil spring and the vehicle
chassis, it is made of high-elasticity rubber that absorbs over 80%
of vertical vibrations (10-200Hz) generated by the coil spring when
driving over bumps, potholes, or uneven roads. This minimizes
vibration transmission to the chassis and cabin, significantly
improving ride comfort.
- Spring & Chassis Protection: It forms a protective barrier between the metal coil spring and
the chassis mounting point, preventing direct metal-to-metal
contact that causes wear, scratches, or paint damage. Additionally,
it restricts lateral movement of the spring during cornering,
extending the spring’s service life by 30% compared to unprotected
setups.
- Noise Reduction: Its specialized porous rubber structure dampens high-frequency
"squeaking" or "clunking" noises caused by the spring rubbing
against the chassis. This eliminates annoying suspension noise,
which is particularly noticeable during low-speed driving on rough
surfaces.
Replace this rear coil spring dumper upper isolator pad cover
immediately if you observe the following symptoms, which indicate
wear or failure:
- Rear Suspension Noise: A "squeaking" or "metal-on-metal" sound from the rear when
driving over bumps, potholes, or speed bumps—caused by worn,
cracked, or missing pad covers that leave the spring in direct
contact with the chassis.
- Visible Damage: The pad cover is cracked, torn, hardened, or completely detached;
the rubber material is brittle or has significant compression set
(flattened and unable to rebound)—losing its vibration isolation
and protective capabilities.
- Uneven Spring Wear: The upper end of the rear coil spring shows uneven wear marks or
scratches, indicating the pad cover is no longer properly
cushioning or aligning the spring.
- Reduced Ride Comfort: Increased vibration is felt in the rear cabin during driving,
especially on rough roads—due to degraded rubber elasticity that
fails to absorb impacts.
- 1× Rear coil spring dumper upper isolator pad cover (1188471-00-C)
- 1× Installation guide (with diagrams showing spring and pad
alignment)
- 1× Silicone lubricant packet (eases installation and extends rubber
service life)
- Jack + jack stands (to safely lift the rear of the vehicle and
relieve spring tension)
- Pliers (to remove any remaining fragments of old pad covers)
- Wire brush (to clean rust, debris, or dirt from the chassis
mounting point before installation)
- Safety First: Use a jack to lift the rear of the vehicle and secure it with
jack stands—never work under a vehicle supported only by a jack.
This relieves tension on the rear coil springs, making pad cover
installation easier.
- Clean the Mounting Surface: Use a wire brush to remove debris, rust, or fragments of the old
pad cover from the chassis mounting point—ensure the surface is
clean for proper adhesion and alignment.
- Proper Alignment: Align the pad cover’s inner diameter with the chassis mounting
pin and its outer edge with the upper end of the coil spring—ensure
it fits snugly without twisting or stretching.
- Lubrication Tip: Apply a thin layer of the included silicone lubricant to the pad
cover’s surface before installation to reduce friction and prevent
tearing during fitting.
- Warranty Service: Provides a 3-year/40,000-kilometer warranty (whichever comes
first). During the warranty period, if the pad cover cracks, tears,
or hardens prematurely (non-human damage), a free replacement will
be provided.
- Technical Assistance: A dedicated support team is available via chat or email to answer
installation questions (e.g., alignment tips, spring tension
relief) and troubleshoot post-installation issues.
- Compatibility Guarantee: 7-day no-reason return is supported if the pad cover is
incompatible with your 2017-2023 Model 3/Model Y (provided the
product is unused and in its original packaging).
If you need to confirm compatibility with your specific Tesla model
(e.g., 2022 Model Y Performance) or have questions about
installation steps, please click "Contact Us" or send a message via
the chat box—our team will respond promptly with personalized
support. For bulk purchase needs (e.g., repair shops, fleet
maintenance), we also offer flexible, negotiable terms to meet your
requirements.
