Coil-Over Eliminator 5in Conventional Spring

The Coleman Racing Products Coil-Over Eliminator 5-inch Conventional Spring (MPN 450-180) replaces coil-over suspension systems with a straightforward, maintenance-friendly spring solution. This kit compresses to 14 inches and extends to 20.5 inches, providing consistent damping characteristics for racing, towing, or performance driving applications where simplicity and reliability outweigh coil-over adjustability.

The 5-inch conventional spring design delivers linear spring rate progression, making it predictable under load and straightforward to set up without complex tuning. Pre-assembled cups and rod ends are included, eliminating the need for separate bearing or bushing sourcing. At 5.7 pounds per unit and measuring 5 × 5 × 15 inches, this eliminator fits standard suspension mounting points while keeping rotating mass minimal. The conventional spring formula is inherently more durable than coil-over setups in high-vibration or off-road environments, where bearing wear and seal degradation plague complex systems.

This kit suits builders prioritizing durability and cost-effectiveness over infinite adjustability. Off-road racers, vintage restoration enthusiasts, and hauling operations benefit from the spring's straightforward behavior and low maintenance overhead. The included rod ends and cups ensure bolt-in installation without adapter hunting, making this a complete system rather than a partial component requiring additional fabrication.

Conventional springs remain the industry standard for reliability because they eliminate seal failures, bearing preload issues, and damper stiction common to coil-over designs. Coleman Racing Products' 450-180 applies that proven engineering to modern suspension replacement, offering a no-nonsense alternative to adjustable systems when predictability and longevity are the priority.
