Description

Step up your 1993-1989 5.0L Mustang with an awesome upgrade: the QA1 (HK23-FMM1) Level 3 Handling Suspension Kit with Pro-Coilovers! QA1 Tubular K-Member is made from HSLA steel, which is a high strength, low alloy steel. This K-member comes in a sleek black powder-coated, high gloss finish. This K-member is 50 percent lighter than the factory K-member and is made in the USA. QA1 designed the lower control arm brackets to be raised, which corrects roll center when your Mustang is lowered. This K-member also maintains optimum anti-dive geometry with minimized bump steer issues. Ideal for street performance and autocrossing applications, this K-member gives you the ability to change the steering geometry with stainless steel steering rack relocation inserts. You can choose to run the steering rack in the stock location, or raise the rack for maximum performance.

The Front Double Adjustable Pro-Coilovers feature a Twin-tube style strut with a threaded sleeve body. The threaded sleeves allow the collar to adjust the ride height on your 1979-1989 Mustang. The Front Pro Coilovers come with 200lbs springs that are 2” in Diameter. The Front Coilovers have an extended length of 20.87” and collapsed length of 14.62”. The Double Adjustable Struts have 18 clicks of compression and 18 clicks of rebound adjustments so the customer can finely tune the front suspension on your 1979-1989 Mustang. Once the Strut Body is fully constructed it is then powder coated in a Silver finish.

The QA1 Handling Kit includes a Pair of Caster Camber Plates. The Caster Camber Plates are designed to help adjust the Caster and Camber on your Mustang after you lower it. The Caster Camber Plates are a two-piece design, this makes adjusting the Caster and Camber simple and straight forward. The Caster Camber Plates are constructed from heavy gauge aluminum and feature a bearing housing that is Tig-Welded to the main plate to increase the strength and performance. The Caster Camber Plates are proudly made in the USA!

The Front Lower Race Control Arms will reduce unsprung weight while improving weight distribution in race applications. QA1 Mustang tubular control arms require the use of QA1 coil-over struts. QA1 caster camber plates are recommended. Get a substantial weight savings of 15 lbs.. The Tubular Front Lower Control Arms are built with rod ends, this allows the customer to finely tune the alignment specs for their Mustang.

The QA1 Front Sway Bar is constructed from Lightweight Hollow-Core 4130 Chromoly Steel for maximum strength and durability. The CNC formed Sway Bar will ensure a precision fitment for a true bolt-on installation. The Front Sway Bar includes adjustable end links for fine tuning of the roll stiffness. Also included with this Front Sway Bar is a pair of greaseable graphite polyurethane bushings. Once the Front Sway Bar is fully constructed it is then powder coated in a gloss black finish to help mimic the other QA1 Suspension products.

The Double Rear Shock provides 18 positions of compression adjustment and 18 positions of rebound adjustment, for a total of 324 possible valving combinations. The Rear Shock has a fully threaded body allowing for ride height adjustability. The Rear Coilover kit includes 130lbs. rate spring with a 2” diameter body.

The Adjusting Rod is 1-1/4” in diameter that is a hex style design that allows the customer to adjust the upper control arm with a Wrench. The Rod Ends are greaseable, this will prevent the Rod End from making noise. With the Upper Control Arms being double adjustable, adjustment can be made on the vehicle. QA1 also includes new rear end bushings that will eliminate rear end flex. Grade 8 mounting hardware is also included.

The Rear Lower Control Arms are constructed from .120” wall cold rolled steel for maximum strength and flex elimination.
