Product Details

The QA1 GD507-10750C is a front Pro Coil double adjustable coilover shock kit designed as a bolt-in upgrade to convert stock front suspension to a fully adjustable coilover system. Featuring a lightweight billet aluminum shock body with a clear anodized finish, this kit delivers race-proven performance across a wide range of driving applications — from street performance and street rod builds to autocross, road racing, and drag racing.

The double adjustable twin-tube shock design provides 18 positions of rebound and 18 positions of compression adjustment, yielding 324 unique valving combinations to precisely dial in your ride and handling characteristics. The fully threaded shock body allows for ride height adjustment, giving you the ability to fine-tune stance and corner weight balance with ease.

Included is a 10-inch, 750 lb/in silver powdercoated coilover spring specially designed for QA1's Pro Coil systems. These American-made high-travel springs feature fewer coils and a reduced wire diameter, increasing coil travel distance for enhanced suspension performance. The result is reduced unsprung weight and faster spring response for improved handling.

Great

PERFECT!!!

Good

boatplicity provided the prop paint product that I needed and wanted at a very good price. Why pay the overpriced WM item? Ordering was easy, the free shipping option was a great feature and helped me go with boatplicity for my order. Shipping time was good. Didn't need it immediately and I loved the opportunity to use their offer.

Love the price of tires

very good
