Product Description

The Bilstein 19-248257 is a B4 OE Replacement rear shock absorber for the 2016-2019 Smart fortwo and Smart EQ fortwo (chassis 453). The B4 series is Bilstein's direct OE replacement line, developed specifically to restore a vehicle to its factory suspension performance. On the Smart 453's rear-engine, rear-wheel-drive layout, the rear shock absorbers play a particularly important role in maintaining straight-line stability, cornering balance, and overall handling composure - worn rear dampers on these cars produce noticeably vague, unsettled behavior that the 19-248257 directly addresses by returning damping to factory specification.

The twintube gas pressure design with application-specific valving for the 453 platform's rear suspension geometry and spring rates delivers consistent performance across all driving conditions. Replaces OEM Smart/Mercedes-Benz part number 453 326 05 00. Sold individually - order two for a complete rear axle replacement. Backed by Bilstein's Limited Lifetime Warranty against manufacturer defects.
