Dasbecan front lower control arm bumper stop 2-piece set for Chevy/GMC trucks – microcellular polyurethane, OEM-fit

Dasbecan Front Lower Control Arm Bumper Stop (2 pieces) is a direct-fit replacement made from high-strength microcellular polyurethane to cushion control arm travel and reduce suspension vibration.

These front lower control arm bumpers are engineered to replace worn or damaged stops on compatible Chevrolet and GMC trucks and SUVs. Designed to meet or surpass OEM fit and function, the pair installs into the vehicle's original mounting location without custom modification. They serve as the last line of suspension travel, preventing metal-to-metal contact and dampening harsh impacts from road irregularities.

Which vehicles will these bumper stops fit?

The Dasbecan bumpers are produced to match specific OEM part numbers (K201426, K201426B) and fit a broad range of Chevrolet and GMC models. Check the vehicle list carefully to confirm compatibility before purchase. Fitment covers model years and variations commonly used on heavy-duty and full-size trucks.

• Avalanche 1500 (2005–2006) and Avalanche 2500 (2002–2003, 2005–2006)
• Silverado & Sierra 1500/2500/3500 series including HD and Classic model years listed
• Suburban 2500 (2000–2013) and Tahoe (1995–2000)
• Reference OEM numbers K201426 and K201426B for a precise match

How do these bumper stops improve ride quality?

By absorbing energy at full suspension compression, the bumpers reduce harsh shock transfer to the control arm and chassis. That cushioning effect limits clunks and vibration that occur when the suspension reaches its travel limit. The microcellular polyurethane construction returns to shape after impact, maintaining consistent performance over time.

• High-strength polyurethane cushions extreme compression events
• Reduces noise, vibration, and harshness when hitting bumps or potholes
• Maintains shape for prolonged, repeatable impact absorption

What are the material and quality standards?

These stops are manufactured from microcellular polyurethane chosen for durability, tear resistance, and impact absorption. Production follows factory testing protocols to ensure dimensions and mechanical properties match the original equipment they replace. The parts are intended to meet or exceed OEM standards for fit and performance.

• Microcellular polyurethane provides high tensile and impact resistance
• Factory-tested to ensure direct-fit installation and correct geometry
• Sold as a set of two bumpers for one vehicle's front suspension

How simple is installation and what’s included?

Installation is straightforward for anyone with basic suspension service skills and common hand tools. The bumpers are designed to seat into the control arm mounting location used by the original parts, so no trimming or fabrication is required. Each package contains two front control arm bumpers—one pair to replace both sides.

• Direct replacement for the original control arm stops—no modification needed
• Comes as a pair (Control Arm Bumper x2pcs)
• Fits original mounting sockets and retains factory clearance specs

Who is this for: Owners and technicians servicing Chevrolet and GMC full-size trucks and SUVs who need a reliable, OEM-matched replacement for worn front lower control arm bumper stops. This part suits fleets, restoration projects, and routine suspension maintenance where restoring correct travel limits and reducing impact noise are priorities.
