ECOTRIC New Coil Over Coil-Over Shock Mount Kit C2047
Best for: DIY enthusiasts and performance builders who need a highly adjustable lower mount for coilovers. This CNC laser-cut kit offers a minimum 6 inches of height adjustment, making it suitable for vehicles undergoing chassis work or suspension swaps where ride height and shock travel must be tuned precisely. The kit specifies a 3-inch axle tube diameter and natural finish for straightforward fabrication and fitment. Consider this option if you require substantial vertical adjustment without replacing the entire mounting system. Caution: installation requires welding or compatible mounting points on the chassis; verify tube diameter and shock compatibility before purchasing.
3″ Rear Lower Shock Bracket for 3″ Axle Tube
Best for: Vehicles with narrowed rear ends where factory shock locations are unusable. These universal weld-on L-brackets for 3-inch diameter axle tubes are designed to relocate coilovers inboard and vertically, enabling proper shock travel and better handling. They offer adjustable installed height, which helps tailor ride quality for track days or aggressive street driving. Limitation: Weld-on installation requires metalwork and precise alignment to avoid binding or misalignment of the coilover assembly.
maXpeedingrods Universal Coil Over Kit for 3″ Axle Tubes
Best for: Builders needing a versatile adjustable lower bracket solution for 3″ axle tubes. The kit includes up to 6 inches of vertical positioning, making it well-suited for chassis modifications or axle narrowing. It’s designed to relocate coilovers inboard and vertical, providing a solid mounting point for racing coil-over shocks. A caution: check that your coilover body and mounting hardware are compatible with the provided L-brackets and spacers.
Allstar ALL60106 Wide Flat Mount Style Weld-On Bracket
Best for: Builders seeking a simple, wide flat weld-on solution compatible with round or rectangular tubing. This bracket comes with a bolt, locknut, and spacer, simplifying installation where a wide, flat mounting surface is advantageous. Choose this if your chassis uses non-standard tubing or you want a straightforward mounting option without complex brackets. Limitation: May require precise welding alignment and space for bolt-head clearance in tight installations.
Allstar Performance Upper Coil Over Shock Mount Kit Rear ALL60230
Best for: Rear coilover mounting where an upper support is required. The ALL60230 kit includes a 48″ long mild steel tube, with 1-1/2″ wall thickness and reinforced mounting tabs. This solution is suitable for vehicles needing sturdy upper support with multiple mounting points. Use this when you require robust upper attachment for consistent ride height and improved straight-line stability. Limitation: Longer tube length may necessitate additional space and precise alignment during installation.
Buying Guide
- Compatibility: Confirm axle tube diameter (commonly 3″) and whether brackets are weld-on or bolt-on. Select brackets that match your coilover shock body’s mounting style and travel range.
- Height and travel: If your goal is precise ride height, choose brackets offering substantial vertical adjustment (often up to 6 inches). For simpler alignment, fixed or upper-mupport kits may be preferred.
- mounting location: Decide between rear lower, upper, or wide flat weld-on brackets based on your chassis design and available space. Lower mounts influence anti-squat and rebound behavior; upper mounts affect shock angle and clearance.
- Fabrication needs: Weld-on brackets require welding skill and proper tooling. Bolt-on or bolt-through designs reduce fabrication but may need adapters or spacers for proper fit.
- Material and finish: Steel brackets provide strength, while aluminum variants can reduce weight. Natural or coated finishes influence corrosion resistance and appearance.
FAQ
- What is the primary difference between weld-on and bolt-on coilover brackets?
Weld-on brackets require welding to the chassis for mounting, offering strong, permanent attachment; bolt-on brackets use hardware to connect to existing mounts and are easier to install but might be less rigid. - Do I need 6 inches of vertical adjustment?
If you plan to modify ride height significantly or compensate for chassis changes, 6 inches of adjustability provides flexibility. For minimal changes, a fixed height may suffice. - Can these brackets be reused on different vehicles?
Some universal weld-on brackets are adaptable, but confirming axle tube diameter, shock mounting location, and chassis clearances is essential before reuse on a different build. - Is upper coilover mount necessary for all coilovers?
Not always. Upper mounts are critical when there is limited space or when you need a specific shock angle and spline alignment. Many rear setups can function with lower mounts plus appropriate hardware. - Will these brackets affect suspension geometry?
Yes. Adjusting ride height, mounting position, and shock angle can influence bump steer, anti-squat, and overall handling. Alignments after installation are recommended.
