Coil Over Kit Large Body 2-1/2in Spring

The Coil Over Kit Large Body 2-1/2in Spring by GENESIS SHOCKS is engineered for drivers and fabricators seeking serious suspension geometry control and ride refinement. This adjustable coil-over assembly addresses the core demand in performance vehicle builds: independent spring preload and dampening adjustment without factory suspension constraints. Whether you're lowering a daily driver, building a track-focused platform, or dialing in geometry for handling optimization, a quality coil-over kit separates amateur bolt-on upgrades from professional-grade suspension architecture.

GENESIS SHOCKS engineered this large-body unit around a 2-1/2 inch spring diameter, a proven standard that balances spring rate authority with packaging practicality on full-size and large-displacement platforms. The adjustable collar design allows you to fine-tune ride height and spring preload independently, a critical feature when dialing out bind or matching corner weights across the chassis. Precision-machined components and corrosion-resistant construction ensure reliability through repeated adjustment cycles and harsh road conditions. The compact 3.3 x 2.2 x 6.7 inch profile fits within typical strut housing while maintaining clearance for full suspension travel.

Fabricators and suspension tuners rely on large-body coil-over kits like this one when retrofitting independent geometry into trucks, SUVs, and custom chassis where factory springs fall short. The 0.55 lb weight per unit keeps unsprung mass minimal—critical for maintaining tire contact patch and reducing energy loss through the suspension articulation. Installation demands proper tools, alignment equipment, and knowledge of your specific platform's mounting points; professional installation is recommended to ensure correct geometry, safe preload settings, and optimal dampening calibration.
