Shock and SpringsThese silver powder coated springs fit perfectly with QA1’s Pro Coil Shock Systems. Made with the highest quality materials, QA1 springs are strong, consistent and have a long life. Features 3.5″ upper i/d, 2.5″ lower i/d, and a 10″ length.
Chrome Silicon Steel (CrS)
Cold Wound – Heat Treated – Shot Peened
All QA1 springs go through intensive manufacturing processes to ensure consistency, accuracy and durability.
Protective Coated
QA1’s GM Pro Coil  springs are silver powder coated for excellent longevity.
High Travel Options
Springs with HT in the part number are high travel springs. The high travel springs have fewer coils and a smaller wire diameter. As a result, they are lighter and have increased travel due to the larger distance between the coils. These lighter springs reduce unsprung weight and react faster, optimizing suspension performance.
Lengths and Rates Marked
All QA1 springs are clearly marked with the free length of the spring and spring rate for quick and easy identification.
LIFETIME GUARANTEE
All QA1 springs are lifetime guaranteed to remain within 2% of the original free height and rate under normal operating conditions.
Coilover Plates
Speedway tubular coilover plates allow you to reinforce the lower control arm when running coilovers.
- 5-1/2 inch outside diameter
- 1/4″ thick

Prepping Control Arms for Coil-Overs – 1967 Chevelle
As promised, this article dovetails off the end of the control arm article. Since these two projects were done concurrently, now seems like a good time to cover the process of prepping these arms for use with coil-overs.
Normally the front shock absorber mounts from below the control arm with bolts that tread into a speed nut or welded nut (in this case) on the lower control arm. When you change that shock absorbers work load to also include supporting the weight of the vehicle, which requires that you place that load on top of the control arm in order for the load to transfer to the arm via direct contact rather than through the tensile load on the bolts. Below, I’ll detail the steps that I took to ensure this conversion would perform and last
