ECOTRIC Coil-Over Shock Mount Kit C2047 for 3" Axle — Weld-On Adjustable Lower Brackets, 6" Height Range

This kit supplies a durable, laser-cut bracket assembly designed to convert existing rear axle housings into adjustable coil-over locations. Made for fabricators and performance builders, the components arrive in a natural finish and require welding during installation. The C2047-style layout mirrors common competition mounts, providing predictable geometry and a broad range of ride-height tuning without custom machining.

How does this bracket kit change suspension adjustability?

The ECOTRIC kit lets you alter ride height and shock travel by relocating the lower mounting point along a 6" vertical range. Moving the mounting position impacts corner weight and spring pre-load, enabling quick setup changes for street, track, or towing setups. Because the brackets are CNC laser cut, the holes and slots line up for repeatable adjustments.

• Adjustability: up to 6 inches of vertical movement
• Compatibility: fits most coil-over shocks on the market
• Precision: CNC laser-cut bracket faces for accurate alignment
• Installation: weld-on design for permanent, strong attachment

What parts are included and what hardware will I need?

The package contains two weld-on housing brackets sized for 3" axle tubes, four 3/16" thick L-brackets for mounting shocks, and the bolt kit needed to secure shocks and brackets. It mounts two shocks (left and right) and supplies the primary fasteners; additional welding consumables and mounting hardware for specific shock models may be required. This is a kit for fabricators — some trimming or fitment work is common depending on axle and shock choice.

• Included: 2 weld-on brackets for 3" axle tubes
• Included: 4 x 3/16" L-brackets for shock connection
• Included: bolt kit for bracket and shock attachment
• Not included: welding tools and shock-specific bushings or spacers

Will this fit my axle and coil-over shocks?

The ECOTRIC C2047 lower mount kit is built for 3" diameter axle tubes and is compatible with most popular coil-over shock bodies that use standard lower-eye mounting hardware. Always verify the shock eye size and the shock body clearance in the chosen mounting position before welding. If your axle tube diameter differs, or your shock uses proprietary mounts, an adapter or alternate bracket will be required.

• Axle tube compatibility: 3" diameter
• Shock compatibility: most coil-over shocks with standard mounting eyes
• Fit check: confirm eyelet spacing and clearance before welding
• Modification: adapters may be needed for nonstandard shocks or axles

How difficult is installation and what tools are recommended?

Installation is intended for users with fabrication experience; welding is required to secure the housing brackets to the axle tube. For a reliable result use a clean, properly fitted bracket, tack in position, check alignment, then finish weld. Recommended tools include a MIG/TIG welder, angle grinder for surface prep, torque wrench for final hardware, and measuring tools for precise ride-height setup.

• Required: welding equipment and safety gear
• Helpful: angle grinder, measuring tape, level, and clamps
• Torque specs: follow shock manufacturer recommendations for fasteners
• Tip: test-fit and tack-weld before final welding to ensure correct geometry

Who is this for? ECOTRIC's adjustable coil-over shock mount kit C2047 is aimed at builders, racers, and custom-fabrication shops looking to add or upgrade rear coil-over mounts on vehicles with 3" axle tubes. It suits anyone who wants reliable, repeatable height adjustment and is comfortable performing weld-on installations or working with a professional welder. If you need a bolt-on non-weld solution or have nonstandard axle dimensions, consider asking about alternative mounts or custom fabrication options.
