Fitment Notes

• Fits Jaguar S-Type models equipped with CATS (Computer Active Technology Suspension) only - does NOT fit S-Type variants with standard passive suspension
• CATS is identified as the factory adaptive/electronic damping system on these vehicles; verify your vehicle's suspension specification before ordering
• This is a spring-bearing shock absorber - the front coil spring mounts directly to the included spring seat integrated into this unit
• Dust boot not included
• Not recommended for use with lowering springs - engineered to maintain factory ride height and OE ride quality
• Sold individually - one shock absorber per unit; two required for a complete front axle replacement
• Replaces OEM Jaguar part numbers including: XR8 52372, XR8 52370, XR8 52374, XR8 47877, XR8 43732, XR8 43730, XR8 36064, XR8 26829, 2R83 18045 EC, 2R83 18045 ED

Features

• B4 DampTronic designation means this is a direct OE replacement for the electronically controlled dampers found on CATS-equipped Jaguar S-Type models - plug-and-play compatibility with the factory adaptive suspension electronics
• Monotube gas-pressure design provides superior heat dissipation and consistent damping performance compared to twin-tube designs, maintaining the S-Type's refined ride and handling characteristics
• Spring-bearing design with integrated spring seat carries the factory front coil spring directly - maintains correct front suspension geometry and load distribution
• Stem upper mount and clevis lower mount correspond precisely to the factory front suspension attachment points - direct bolt-on replacement using existing hardware
• Engineered and validated to meet or exceed Jaguar's original equipment specifications for the CCX S-Type platform
• Green painted finish - the DampTronic-series identifier within Bilstein's product line
• High power reserves ensure maximum safety and ride stability under all load and speed conditions
• Backed by Bilstein's Limited Lifetime Warranty against manufacturer defects for gas pressure shock absorbers

Product Description

The Bilstein 20-070854 is a B4 OE Replacement DampTronic front shock absorber engineered specifically for the 2003-2008 Jaguar S-Type (CCX platform) equipped with the factory CATS (Computer Active Technology Suspension) adaptive damping system. As a DampTronic unit, this shock is a direct electronic replacement for the factory adaptive damper - it maintains full compatibility with the CATS control electronics, plug-and-play with the existing wiring and sensors, while restoring or improving the front suspension's damping behavior. The spring-bearing design includes an integrated spring seat that carries the factory front coil spring, maintaining the correct front suspension geometry without requiring any supplemental hardware.

The CATS system on the S-Type continuously varies damping force based on road conditions and driving inputs, and replacing it with a non-DampTronic passive shock would eliminate this functionality and likely trigger fault codes. The 20-070854 preserves the full CATS system operation while delivering the OE-level ride quality, handling precision, and damping response the S-Type was engineered to provide. It is critical to verify your vehicle's suspension specification before ordering - S-Type variants without the CATS adaptive suspension use different Bilstein part numbers and are not compatible with this unit.

Built on Bilstein's 46mm monotube gas-pressure design, the 20-070854 provides superior heat dissipation and damping consistency compared to the twin-tube alternative, ensuring stable and fade-free performance across the S-Type's full range of CATS-adjusted damping settings. The green finish identifies it as part of Bilstein's DampTronic product range. This shock is not recommended for use with aftermarket lowering springs, as it is calibrated for stock ride height. Two units are required for a complete front axle replacement, and it is backed by Bilstein's Limited Lifetime Warranty against manufacturer defects.
