Bilstein B6 Long Travel Rear Shock Absorbers — Mazda BT-50 2020-On

These Bilstein B6 Long Travel shocks do not provide lift themselves — they are designed to work with existing 0-3" lift configurations achieved through upgraded coil springs, leaf springs, or spacer kits. The "Long Travel" designation refers to the extended compression and droop travel compared to standard-length shocks, allowing your suspension to fully utilize the additional clearance without bottoming out or topping out. If you're building a complete lift system, you'll need to pair these rear shocks with appropriate lifted rear leaf springs or coil springs depending on your BT-50's suspension setup. Our team can help you select the complete package for your desired lift height.

This package includes 2 x Bilstein B6 Long Travel rear shock absorbers with factory-fitted bushings and all necessary mounting hardware for direct bolt-on installation to your Mazda BT-50. Each shock features Bilstein's monotube gas pressure design, high-pressure nitrogen charge, multi-lip premium seals, and zinc-plated corrosion-resistant finish. The shocks arrive pre-charged and ready to install with no additional preparation required. Please note this is a rear pair only — front shocks, springs, U-bolts, and other suspension components are sold separately and should be selected based on your complete suspension setup requirements.

Yes, these Bilstein B6 Long Travel shocks are excellent for towing applications up to your BT-50's rated towing capacity. The monotube gas pressure design and velocity-sensitive damping provide enhanced rear-end control, reduced sway, and improved stability when towing caravans, boat trailers, or work trailers. The shocks work effectively with constant loads from tow ball weight and help maintain level vehicle attitude under towing conditions. For BT-50 owners who frequently tow heavy loads or prefer adjustable load support, consider supplementing these shocks with airbag suspension, which allows you to dial in additional support when loaded while maintaining comfortable ride quality when unladen.

Control arm upgrades are not mandatory when fitting these Bilstein B6 rear shocks, as rear suspension on the BT-50 uses leaf springs rather than control arm geometry. However, if you're running a 2-3" front lift to match your rear height, upgraded front control arms become highly recommended to correct caster angles, prevent ball joint binding, and maximize front suspension articulation. Control arms ensure proper suspension geometry at lifted heights, reducing steering wander and component wear. Many BT-50 owners choose to upgrade both front and rear suspension simultaneously for balanced performance, and our team can recommend complete packages that pair these rear shocks with appropriate front suspension components including control arms, coil springs, and front shock absorbers.

Yes, a full four-wheel alignment is mandatory after installing these Bilstein rear shocks, particularly if you're changing rear ride height or replacing worn shocks that may have allowed suspension settling. While rear alignment adjustments on the BT-50 are limited compared to front adjustments, any change in vehicle stance affects steering geometry, toe angles, and overall handling characteristics. Professional alignment ensures even tyre wear, predictable steering response, and optimal handling safety. Your alignment technician should set specifications to manufacturer recommendations adjusted for your new ride height, and most 4WD workshops experienced with lifted vehicles will have appropriate alignment settings for common BT-50 lift configurations.

These Bilstein B6 rear shocks are sold as a pair without springs included, giving you complete flexibility to match them with leaf springs rated for your specific constant load requirements. When selecting rear leaf springs separately, always choose spring rates based only on permanent accessories like canopies, drawer systems, dual batteries, and auxiliary fuel tanks — not occasional loads like camping gear or passengers. The Bilstein B6 damping is tuned to work effectively across a range of spring rates, providing excellent performance whether you're running light-duty, medium-duty, or heavy-duty leaf spring configurations. Our suspension experts can help you calculate your constant load and recommend the ideal spring rating to pair with these shocks for optimal ride quality and load-carrying capability.

These Bilstein B6 rear shocks are designed for 0-3" lift applications, and when combined with appropriate front lift components, this height range typically allows fitment of 265/70R17 to 275/65R18 tyres on the current-generation Mazda BT-50 without major modifications. At the upper end of the 3" lift range, some owners successfully fit 285/70R17 tyres with minor trimming of plastic guards. The long travel design provides additional compression travel, reducing the risk of tyre contact with guards during full suspension compression off-road. Final tyre clearance depends on your specific lift height, wheel offset, and driving conditions. We recommend consulting with experienced BT-50 builders or our suspension team before committing to aggressive tyre sizes to ensure clearance at full lock and full compression.

Bilstein backs these B6 Long Travel shock absorbers with a comprehensive manufacturer's warranty covering defects in materials and workmanship under normal operating conditions. The warranty is valid when shocks are installed correctly by a qualified technician, paired with appropriate spring rates, and used within the manufacturer's specified load and application guidelines. Warranty claims are processed through 4WD Suspension Australia with support from Bilstein's Australian distributor, ensuring local warranty service without international shipping delays. To maintain warranty validity, retain your proof of purchase and ensure shocks are installed according to Bilstein specifications. This warranty demonstrates Bilstein's confidence in their German-engineered monotube technology and long-term durability under Australian touring and working conditions.

Yes, the Bilstein B6 range is specifically engineered to balance daily driving comfort with off-road capability, making them ideal for BT-50 owners who use their vehicle as both a daily commuter and weekend tourer. The velocity-sensitive digressive piston design provides compliant damping over small bumps and road imperfections during highway cruising, while automatically firming up during harsh impacts or high-speed corrugations. This results in a noticeably more controlled and confidence-inspiring ride compared to worn factory shocks, without the harsh, jarring character of hardcore competition dampers. Many BT-50 owners report the B6 delivers a comfortable, planted feel on sealed roads while eliminating the bounce, float, and rear-end wander common with factory shocks on lifted vehicles, making them perfect for the 80-90% on-road, 10-20% off-road usage pattern typical of most Australian 4WD owners.
