Nakuuly Front Bumper Stops
Nakuuly’s front bumper stops are a replacement option for a range of listed Chevrolet, GMC, and Cadillac vehicles. The product identifies K201426, K201426B, and KR1426 as replacement part numbers and describes itself as a direct replacement, rather than a genuine OEM part.
Best for: Owners of a vehicle included in the product’s compatibility list who need a bumper associated with those part numbers. Listed applications include select Silverado and Sierra trucks, Avalanche models, Suburban 2500, Tahoe, Yukon, and Escalade vehicles across specified years.
The listing connects rattling or harsh noise over uneven roads with a potentially failing bump stop. Limitation: The fitment list is lengthy and year-specific, so verify the exact vehicle and part number before ordering.
ZONFANT Control Arm Bumper
ZONFANT lists this bumper as a replacement for K201426, K201426B, and KR1426. Its compatibility information covers specified Cadillac, Chevrolet, and GMC vehicles, including various Silverado, Sierra, Tahoe, Yukon, Avalanche, and Suburban models.
Best for: Buyers seeking a listed GM-vehicle application and a bumper intended to cushion contact between the control arm and frame. The product description says the rubber bumper helps mitigate impact when a vehicle bottoms out.
Choose this if your vehicle and replacement number match the listing. Limitation: The manufacturer specifically advises confirming compatibility before purchase; not every year or trim is covered.
Dorman 523-092 Front Bumper
The Dorman 523-092 is described as a front lower forward suspension control arm bumper. Dorman says it is a direct replacement for specific vehicles, with dimensions precision-engineered to match original components and construction made to stated standards.
Best for: A buyer whose vehicle catalog or repair information identifies Dorman part 523-092 as the required front lower forward bumper. Its position-specific name helps distinguish it from other control arm bumpers.
Limitation: The provided product details do not identify compatible makes, models, or years. Confirm that 523-092 is specified for your vehicle instead of relying on the product name alone.
Dorman 523-088 Control Arm Bumper
Dorman 523-088 is a front lower suspension control arm bumper. The listing describes it as a direct replacement for specific vehicles and says its design and dimensions are engineered to match original components. It also notes durable construction using sturdy materials.
Best for: Owners whose vehicle-specific parts information calls for the 523-088 bumper. Compare it with the 523-092 by the exact part number and installation position, not just the shared Dorman brand.
Limitation: The supplied details do not give a vehicle compatibility list. Verify the part number against your vehicle before buying.
Autoacc Dodge Front Bump Stops
Autoacc supplies two front bump stops for specified 1998–2004 Dodge Dakota and 1999–2003 Dodge Durango applications. The listing restricts fitment to two-wheel-drive models and states that the stops are made from polyurethane foam. It also provides dimensions of 2.25 inches long, 1 inch wide, and 3 inches high.
Best for: Buyers with an eligible 2WD Dakota or Durango who want a pair and can compare the listed dimensions with the required part.
Limitation: The product is expressly limited to 2WD applications; avoid it if your vehicle is four-wheel drive or outside the listed years.
Buying Guide
How do you confirm the correct fit?
Start with your vehicle’s year, make, model, and drivetrain. Then compare those details with the product’s stated application list. If you have the original part number, check it against the replacement number: Nakuuly and ZONFANT list K201426, K201426B, and KR1426. For Dorman, verify the exact 523-092 or 523-088 number using vehicle-specific parts information.
Does bumper position matter?
Yes. Product names may distinguish front, lower, forward, or rear positions. Match the location required by your vehicle rather than choosing a part solely because it is called a control arm bumper. The supplied information identifies Dorman 523-092 as front lower forward and 523-088 as front lower.
When should a bumper be inspected?
Rattling, harsh sounds over uneven roads, or signs of excessive suspension movement can be reasons to inspect the bump stops and related suspension components. These symptoms do not confirm that a bumper is the cause. Have the vehicle assessed if the source is uncertain.
