What body platforms does GTS offer kits for?
Currently, GTS offers kits for A,B,C and E body Dodge/Plymouth/Chrysler cars.
Does the kit come complete and ready to install?
Yes, the kit comes complete from hub to hub with your choice of one of several brake kit options. Kits are shipped with all required hardware and instructions with photos.
Do you offer a sway bar option?
Yes, the GTS does have a sway bar option.
Does the kit come with motor mounts?
Yes, the kit is complete with motor mounts.
Does the kit use factory spindles?
No, this kit is not compatible with the factory Mopar rear steer spindles. The GTS kit uses forged Mustang 2 spindles with an adjustable bump steer stud.
Can I flip the sides of the spindles and make them front steer and use them?
No, this would cause dangerous misalignment of the steering geometry that could result in an accident of some type. The kit MUST use the supplied spindles.
What is the track width, hub to hub of the GTS kit?
The GTS kit has an adjustable track width. The actual track width varies from model to model (A, B/E, C etc) as well as which brake kit. Generally speaking, on an A body, it is adjustable from 58 to 61 inches. Suspension travel 6.5 inches at 58.5 in trackwidth.
How long does it take to install the GTS?
Varies on an individual basis, but typically less than half a day if you have the proper tools and an extra set of hands to help.
Are there any special tools required for the install?
No, the kit can be easily installed with simple and common hand tools.
What power steering pumps work with the QA1 power rack?
For small block and B/RB engines, use the OE pump. Use the Saginaw style on early cars and Federal or TRW style on later cars. CVF brand power steering pumps work well with these racks.
For Gen 3 Hemi swaps, the stock Gen III pump puts out too much pressure for the QA1 steering racks. Several companies modify new and used pumps at a reduced pressure (in the range of 1,100 -1,300 psi), including Bouchillon Performance and Holley.
How do you convert to a Manual Steering rack?
If you want to use a manual rack, use Speedway PN 91034344 or equivalent. The QA1 K-frame features pilot holes for manual rack mounting that must be drilled out. One of the holes overlaps and you’ll need to use a step drill. The manual rack also requires a different steering u-joint to work with the 9/16-26 spline.
Some customers use the power rack with a closed-loop system instead of switching to a true manual rack. The provides the faster ratio (2.75 turns lock to lock vs 3.5 on the manual) without a power steering pump.
What spindles are used with these kits?
QA1 spindles start as Mustang II components and have modified steering arms. Standard Mustang II spindles cannot be used. Both standard height and 2” drop spindles systems are offered. Drop spindles require 18” or larger wheels.
What is the ride height range for standard versus drop spindles?
The ride height range for standard spindles is 0-2” lower than stock and the drop spindles provide 2”-4” lower than stock. Drop spindles require 18” minimum diameter wheel to provide room for the steering arm and outer tie rod end.
What brakes options are available for these systems?
Most front brake kits for Mustang II spindles will work. For the front, QA1 has several Wilwood disc brake options available. Wilwood rotors are dilled for Mopar 5 x 4.5” bolt pattern and 5 x 4-3/4 ”.
The 4-link rear systems can be used with the OE brakes or converted to disk brakes. There are several configurations of axle bearings and offsets on the rear end. We encourage customers to call Wilwood at (805) 388-1188) for rear brake recommendations. It is the buyer’s responsibility to verify wheel/tire fitment for proper backspacing and caliper clearance for their wheels of choice
What parts need to be welded during installation?
QA1’s Mopar front suspension systems are a complete bolt-in installation with the exception of the steering column u-joint. After shorting the steering shaft, the u-joint must be welded to the shaft.
The 4-link rear suspension requires three welding operations:
- Welding of the upper crossmember to the frame rails
- Welding 4 link tabs to the rear end housing (note: this requires 220 V welder and good penetration)
- Rear sway bar upper bracket to frame rails. Sway bar brackets could be bolted as well.
What headers fit with these front suspension kits?
Does the rear 4-link system work with relocated inboard spring location?
The QA1 rear suspension systems will work with both standard spring and inboard spring mounting locations. The unique lower shock mount design allows for this versatility.
