Upgrade your 1963-1987 C10 truck’s front suspension with QA1’s front coil-over conversion kit, designed to deliver great performance and adjustability with your stock chassis. Offering up to 5 inches of drop when used with popular drop spindles, this kit allows you to achieve the perfect stance for your build. With adjustable ride height, you can fine-tune the setup to position the tire in the wheel well exactly where you want it.

FIND YOUR PERFECT STANCE

Achieve the perfect stance for your C10 with QA1’s adjustable coilover conversion kit. With up to 5 inches of drop using popular drop spindles, you’ll have full control over your truck's ride height, giving it the lowered, aggressive look you want.

ENHANCED PERFORMANCE & COMFORT

This kit is designed to offer more than just great looks. The tubular control arms deliver up to 7 degrees of increased caster, dramatically improving stability and giving your C10 the handling characteristics of a modern vehicle. This added caster enhances straight-line stability and makes your truck feel more controlled at higher speeds. Paired with QA1’s single adjustable coilovers, which offer fine-tuned control over ride quality, you can dial in the perfect balance between comfort and performance. Whether you're cruising or cornering, this suspension upgrade provides a smoother, more responsive driving experience.

From the straightforward installation to the inclusion of all necessary hardware, including brand-new lower control arm U-bolts (a feature not commonly found in other kits), every element is designed to ensure a seamless experience. At QA1, we prioritize not just performance but also making your installation process as smooth and hassle-free as possible.
