Description

Upgrade your classic Mustang’s rear suspension with QA1’s complete 4-link system, featuring a custom QA1 9” rear housing. Designed specifically for 1964–1966 Mustangs, this all-in-one solution delivers modern handling, improved traction, and the strength to handle serious power. Whether you’re building a street-driven restomod or a pro-touring performer, this kit is built to transform how your Mustang drives and feels. MODERN HANDLING, CLASSIC FIT QA1’s triangulated 4-link replaces the factory leaf springs with a fully adjustable, geometry-correct rear suspension system. It dramatically improves traction, cornering, and ride quality by eliminating axle wrap and maintaining consistent pinion angle under load. The included QA1 9” rear housing ensures a perfect fit and the durability needed for today’s performance builds. SINGLE ADJUSTABLE COILOVERS This kit includes QA1’s single adjustable shocks, offering 18 clicks of combined rebound and compression adjustment. With one knob, you can easily fine-tune ride comfort and performance for your preferred driving style - from smooth street cruising to spirited cornering. STRONG, RELIABLE, AND READY FOR POWER The included QA1 9” housing features fully formed trailing arm brackets, a fabricated steel center section, and heavy-duty 3” OD axle tubes. Together, they create a rigid foundation capable of handling up to 800 horsepower. Matched 31-spline alloy axles ensure strength and smooth operation mile after mile. RIDE HEIGHT & ADJUSTABILITY Easily dial in your stance with adjustable ride height from factory level to 3” lower. This flexibility lets you fine-tune your Mustang’s appearance and performance without compromising geometry or drivability. EASY INSTALLATION This kit comes complete with everything you need for a straightforward installation - from the housing and brackets to shocks and hardware.

Testimonials

Looks like I get to be the first review for these guys. Let me start out by saying that I have had 3 other cars of a similar caliber to my GTR serviced/worked on and upgrades installed at other shops and none took the pride and level of detail that these guys did. I wish I could see all the welds on the downpipes and exhaust because it looked like artwork. Their fabricator made sure to send me daily updates and pictures which was also a big deal to me. For being an out of state experience it made it seem more like they were local to me and that I had known them for longer.

- James Lowe

Took the leap of faith on buying a set of their R35 intakes and downpipes because the price was half of anyone elses plus their car hauls a** at the track. Install went smooth and the power seems to be even better than advertised. Cant wait to get tuned in a few weeks. Their shelf tune honestly has to be 600+ hp as I pulled on a Hellcat last night. I see these guys and gals going a long ways if they can get out there and advertise. Customer service is on point paired with BIGGG savings for the winning combo.

- Luca Harris

Bought a Motec and had these guys build the harness and set it up fully. Track car that received the level of attention and detail of a show car while here. Made me feel at home every time I popped in for a visit and always offered to buy me lunch/dinner. I don’t see me shopping anywhere else as they make you feel like your family.
