Shock SZ/SL 9in Comp 15 Reb 2

The BILSTEIN Shock SZ/SL 9in Comp 15 Reb 2 (MPN 33-321998) is a monotube shock absorber engineered for vehicles requiring precision damping control and consistent performance across varied terrain. As a single unit in the SZ Series lineup, this shock delivers the monotube design's characteristic responsiveness, combining a 9-inch stroke with BILSTEIN's proprietary C15-R2 valve architecture for controlled rebound characteristics. The 1.81-inch outer diameter and zinc-plated steel construction provide durability in both on-road and light off-road applications.

Technical specifications define this shock's operating window: 14.88 inches fully compressed and 23.52 inches extended, establishing a total travel range suited to mid-range suspension articulation. The monotube design eliminates the gas-oil interface common in twin-tube shocks, reducing fade during sustained use and improving heat dissipation. The C15-R2 valve configuration manages both compression and rebound forces with precision tuning, making this shock suitable for applications where factory damping requires significant upgrade. The zinc-plated finish resists corrosion from road salt and moisture exposure, extending service life in harsh climates.

This shock is specified for vehicles where direct bolt-in replacement or suspension rebuild demands a high-performance monotube unit. Buyers upgrading factory suspension components will find the SZ/SL series' engineering focused on eliminating excessive body roll, reducing nose-dive under braking, and maintaining consistent handling through repeated compression cycles. The single-unit configuration means installation requires matching it with corresponding front or rear companions specific to your vehicle's platform. Verification of vehicle compatibility through the MPN (33-321998) or by consulting BILSTEIN application guides is essential before purchase.
