Description

QA1 1965-79 F-100 coilover conversion systems are suspension kits built with a purpose—just like your truck! With these all-new, engineered-from-scratch systems, you can stop using junkyard parts to modernize your pickup, and instead bolt in the handling and performance you've always wanted. The front systems are 3.75 in. narrower than a Crown Vic, providing ideal handling and allowing fitment of larger wheels and tires. They also save 150 lbs. of weight and provide 3 in. to 5 in. of drop with standard spindles and 5 in. to 7 in. with drop spindles. QA1 1965-79 F-100 coilover conversion systems are available in single and double adjustable styles with everything you need included, except engine mounts.

Included in the systems:

* Adjustable shocks
* High-travel springs
* Coil-over hardware
* Upper and lower control arms
* Upper and lower crossmembers
* Rack and pinion steering
* Stock or drop spindles
* All required nuts, bolts, etc.

Product Overview

You're building your truck for a purpose, paying attention to every detail, every connection, and every movement. We built our system this way, too. With this all-new, engineered-from-scratch system, you can stop using junkyard parts to modernize your pickup and can bolt in the handling and performance you've always wanted. Designed specifically for 65-79 F-100s, the front system is 3.75" narrower than a Crown Vic, providing ideal handling and allowing fitment of larger wheels and tires. The system also saves 150 lbs of weight and provides 3" to 5" of drop with standard spindles and 5" to 7" with drop spindles. Everything you need is included, all the way down to the hardware. In addition to double- or single-adjustable shocks and high travel springs, you get upper and lower control arms, upper and lower crossmembers, rack and pinion steering, and stock or drop spindles. All components included in these systems are proudly made in QA1's Lakeville, Minnesota facility. All QA1 shocks are 100% dyno tested and serialized.
