2.5in C/O Kit Koni 7in

The ALLSTAR PERFORMANCE 2.5in C/O Kit with Koni 7in shocks is a coil-over suspension kit engineered for high-performance vehicles requiring precision handling and adjustability. This kit pairs a 2.5-inch ID spring with a 2-inch smooth body Koni shock absorber and 7-inch aluminum sleeve, delivering the stiffness and responsiveness demanded by track drivers, autocross competitors, and serious street enthusiasts.

The black anodized aluminum construction resists corrosion while maintaining a clean appearance under the vehicle. The 2.5-inch spring ID is a common fitment diameter that allows straightforward installation on vehicles with compatible suspension geometry. Koni shock absorbers are recognized in the performance community for their damping consistency across a wide range of track conditions and driving intensities. The 7-inch sleeve length provides adequate support and compression range for both lowered street setups and aggressive track configurations.

This coil-over kit is intended for builders and tuners who need modular suspension components to dial in vehicle balance and ride height independently from damping. It suits street rods, race-prepared domestics, and custom-built performance platforms where off-the-shelf suspension solutions do not meet specific geometry or spring rate requirements. Spring rates and damping adjustments are configured separately, allowing fine-tuning of front-to-rear weight transfer and corner-exit acceleration.

Proper suspension setup depends on accurate measurement and matched spring rates for each corner of the vehicle. Buyers should confirm compatibility with their vehicle's mounting points, control arm geometry, and desired ride height before installation. The kit requires integration with the rest of the suspension system and alignment adjustment post-installation.
