QA1 Trailer Arm Upgrades For Muscle Cars
A trailer arm is a pair of metal links connecting the rear axle to your vehicle. It is a common part of coil spring, live axle and independent rear suspension designs.
The trailing arms are attached to the rear subframe and control arms via bushings. Bad bushings can cause a clunk when the vehicle is in drive, turns or hits bumps.
QA1 Tubular Trailing Arms
QA1 Tubular Trailing Arms are the perfect upgrade for those wanting a lighter, stronger and more aggressive rear suspension setup. They are manufactured from 1-1/4 inch diameter, 0.120 wall cold rolled steel tube for added strength and flex elimination over factory designs. They come with fluted, greasable polyurethane bushings which are superior to the stock rubber bushings and provide improved ride comfort.
They are also adjustable so that you can easily adjust the pinion angle of your lower control arms without having to remove them from the vehicle or change the length of the upper ones. This saves wear and tear on your U-joints and helps maximize your traction when accelerating out of tight corners.
These arms are built with 3 degrees of additional caster to increase drivability and straight-line stability. They are available in both street and race configurations so that you can customize your vehicle to suit your driving style.
The street series of these control arms are designed for vehicles primarily used on the street and offer a factory replacement ball joint for serviceability along with polyurethane bushings to isolate road noise and reduce bind for a smoother ride. The race series of these arms are geared towards drag racing, pro-touring and hard core street applications and include low friction QA1 ball joints and UHMW polyethylene pivot bushings for enhanced performance.
Each set of these arms comes with new ball joints and includes a complete installation kit so that you can easily install your control arms. These arms are constructed of 1/8″ thick, tubular steel and feature a durable black powder coating for long-lasting good looks.
Another important advantage of these arms is that they are made with a spherical ball or rod end assembly that allows the rear Trailer Arm suspension to move more freely and eliminate bushing bind. They also come with greasable polyurethane differential bushings so that you can replace the soft OE differential bushings.
These arms have been tried and tested on many different rigs for thousands of miles, so they are definitely a solid choice when it comes to tubular upper control arms. They may not be as strong or as durable as uniball style arms, but their real-world performance is simply unmatched at this price point.
QA1 Adjustable Trailing Arms
When you want to improve your muscle car’s handling, one of the most effective ways is by replacing your factory stamped steel trailing arms with tubular trailing arms. These American-made trailing arms keep your tires planted firmly on the ground for improved traction and a more predictable, stable ride.
QA1 offers a full line of adjustable upper and lower trailing arms for 1973-1977 GM A-Body vehicles, including Chevelles, Monte Carlos, Cutlasses and Regals. They come in tubular or adjustable styles, offering increased strength for the ultimate in vehicle stability. These adjustable trailing arms also allow for easy and precise pinion angle adjustments without having to remove the arms from your vehicle.
For a classic muscle car with a coil-spring rear end, these trailing arms help reduce wheel hop and increase traction, helping you get better performance at the track. These tubular trailing arms are constructed from 0.120” wall cold rolled steel tubing for maximum strength and flex elimination, and they’re fitted with greasable polyurethane bushings.
The upper trailing arms will increase caster by approximately 3 degrees for better straight line stability and include ball joints, while the lower trailing arms will offer sway bar tabs and feature pivot arms and bushings for an easy installation. They’re powder coated gloss black for long-lasting durability and look great under your vehicle!
Team Z Motorsports uses urethane bushings in their Street Beast lineup of control arms for long life and high resistance to deflection. They have separate adjustability for up to 2 degrees of negative and positive camber so you can achieve your desired alignment specs more easily and precisely.
Total Chaos tubular Chromoly arms are a great option for those who want a stronger, bind and deflection-free option with enough caster and camber correction built in to allow up to 1.5-3 inches of lift. They have 1″ uniballs for excellent articulation and come standard with greaseable urethane bushings in the pivots, although they can be upgraded to 3/4″ Chromoly heim joints for even more deflection free performance.
They have a very strong, bind and deflection-free 1″ uniball for excellent articulation and will allow up to 1.5-3 inches of lift when paired with the right coilovers. They are a solid choice for those who don’t mind spending a little more for the performance and longevity of a tubular Chromoly arm.
QA1 Rear Sway Bar Mounts
Sway bars help reduce body roll and keep your tires firmly planted on the road during hard cornering. They are an easy bolt-on upgrade to give your chassis the stability it needs.
QA1 offers a wide variety of front and rear sway bars for many vehicle applications. These sway bars are designed and road-tested to give your ride the grip that it needs to hold the road.
They are precision CNC-formed, ensuring proper mounting in the stock location for a true bolt-on installation. They also feature adjustable end links to customize roll stiffness to your personal specifications. They are backed by greasable graphite polyurethane bushings and high-quality zinc plated hardware.
Tubular sway bars are a common bolt-on suspension upgrade that can reduce your body roll and improve your handling. They have a larger diameter than your stock bars and are usually made from Chromoly to make them stronger.
These sway bars are typically accompanied by polyurethane bushings that don’t deflect like your stock rubber bushings do, which means that they will last longer. Additionally, they are designed to complement the existing suspension components that you have installed, such as shocks or struts.
This type of sway bar is the easiest to install and will have you on your way to a better handle on the track in no time. They are typically a one-hour job with basic hand tools and are an excellent upgrade to your current suspension.
The sway bar is the most important part of your suspension. Without it, you will feel like your ride is going to roll over every time you turn the wheel.
There are a number of things that will affect the effectiveness of your sway bar, including the material used for its construction, its solid or hollow thickness, and the length of its arms. It is a good idea to go with the largest bar you Trailer Arm can afford, as this will be able to absorb more of your suspension movement than a smaller bar.
QA1 makes a wide array of different sway bars for you to choose from, and they are a great choice if you are looking for an affordable performance upgrade to your ride. They will improve your car’s handling and give you the confidence that you need to tackle any challenge.
