Find the Best Quick Struts for your vehicle — top-rated and reliable options.
This article is part of our Quick Struts Guide.
A quick strut assembly is a complete replacement unit designed to save DIYers time and avoid the most dangerous part of strut work: compressing and transferring the coil spring by hand. Instead of buying a bare strut and moving old parts over, you install one pre-assembled module.
In most cases, a quick strut includes the major wear items that sit above and around the strut itself, such as the coil spring, upper mount, spring isolators, boot, jounce bumper, and often a bearing plate on applications that use one. The exact parts can vary by vehicle and brand, so it is still smart to confirm what is included before ordering.
If you are trying to decide between a loaded quick strut and a traditional bare strut, understanding what comes in the box helps you compare cost, labor, ride quality, and whether you will need any extra hardware.
What a Quick Strut Assembly Usually Includes
A quick strut, also called a loaded strut assembly, is meant to replace nearly the entire strut corner as one unit. Most aftermarket assemblies come with all the major parts already aligned and torqued together.
- Strut/shock body: the main damper that controls suspension movement
- Coil spring: supports vehicle weight and sets ride height
- Upper strut mount: bolts the assembly to the body or strut tower
- Bearing plate or strut bearing: allows the assembly to rotate smoothly on many front strut setups
- Upper and lower spring seats: locate the spring correctly
- Spring isolators: rubber or similar pads that reduce noise and vibration
- Dust boot: protects the strut shaft from dirt and debris
- Jounce bumper/bump stop: cushions suspension travel at full compression
- Retainers or pre-installed hardware on some assemblies
The exact combination depends on the vehicle. Front quick struts often include a bearing because the strut turns when you steer. Rear assemblies may not use a steering bearing, so the included top hardware can be simpler.
Main Parts Explained
Strut Body
This is the actual damper. It controls bounce, body movement, brake dive, and how quickly the spring settles after hitting bumps. If the old strut is leaking oil, feels weak, or lets the vehicle bounce excessively, this is the part that has worn out.
Coil Spring
The spring carries the vehicle’s weight. In a quick strut, the spring is already matched to the strut and installed under tension. That is a big reason many DIYers choose this option. A worn spring can sag, break, or create uneven ride height, so replacing it with the strut can restore the vehicle’s stance and ride quality.
Upper Mount
The upper mount attaches the assembly to the strut tower. It also helps isolate road harshness and vibration from the body. Worn mounts can clunk, shift, or allow excess movement.
Bearing Plate or Strut Bearing
On many front suspensions, the strut turns with the steering. The bearing plate lets that happen smoothly. When it wears out, you may hear popping or groaning while turning, or feel steering bind and spring wind-up.
Dust Boot and Jounce Bumper
The dust boot keeps grit and moisture off the polished strut shaft. The jounce bumper, also called a bump stop, prevents harsh metal-to-metal bottoming during big suspension compression. These are inexpensive parts, but they matter for strut life and ride comfort.
Spring Isolators and Seats
These parts keep the spring properly positioned and reduce squeaks, rattles, and vibration transfer. On an older vehicle, original rubber isolators can be flattened or cracked, so getting them pre-installed is a real benefit.
Parts That May or May Not Be Included
Not every quick strut is packed the same way. Some assemblies are truly complete, while others still require you to reuse a few vehicle-specific pieces.
- New top nuts or mounting nuts: sometimes included, sometimes not
- Sway bar end link hardware: usually not included unless vehicle-specific
- Camber bolts: usually not included
- ABS wire or brake hose brackets: often attached to the strut body, but check shape and hole locations
- Electronic suspension connectors: only present on vehicles equipped with electronic dampers, and many aftermarket quick struts do not support those systems
- Rear upper mounts: may differ by design depending on whether the rear uses a strut or shock/spring arrangement
Always read the product description and compare photos with your original assembly. Two quick struts for the same vehicle may differ in hardware, spring rate tuning, or mount design depending on brand and trim level.
Why Quick Struts Are Popular with DIY Owners
A quick strut is popular because it cuts labor and complexity. Replacing a bare strut usually means disassembling the old unit with a spring compressor, transferring parts, and deciding which old components are still good. A loaded assembly avoids most of that.
- Safer installation for most DIYers because the spring is already compressed and assembled
- Faster repair time with fewer parts to swap over
- More complete refresh because wear items like mounts and bump stops are replaced too
- Less chance of reusing a noisy old mount or weak spring
- Useful on higher-mileage vehicles where multiple suspension parts are tired at once
This is especially helpful when the old spring is rusted, the mount is making noise, or the bearing is binding. If you only replace the damper and reuse worn supporting parts, you may still end up with clunks, steering noise, or a poor ride.
Potential Downsides to Know Before Buying
Quick struts are convenient, but they are not perfect for every job. Some lower-cost assemblies trade precision or ride feel for affordability.
- Ride quality can vary by brand; some feel softer or firmer than original equipment
- Ride height may change slightly if spring rates do not match OEM closely
- Component quality varies; mounts, bearings, and boots may not all be equal
- Less customization if you want to keep OEM springs or choose performance dampers
- May not suit special trims with sport suspension, self-leveling, or electronic dampers
If you care about preserving the exact factory feel, a premium bare strut plus OEM-quality spring and mount components may be the better route. But for many daily drivers, a quality quick strut is a practical and cost-effective fix.
How to Verify What Is Included Before You Order
Do not assume every assembly has the same parts. Before buying, compare the listing, manufacturer catalog, and your vehicle’s original suspension setup.
- Check whether the listing says loaded, complete, or quick strut assembly.
- Look for mention of the mount, bearing, coil spring, dust boot, and jounce bumper.
- Confirm fitment for your year, make, model, engine, drivetrain, and suspension package.
- Compare photos to your old assembly, especially bracket positions for the brake hose and ABS wire.
- See whether new top nuts or mounting hardware are included.
- If the vehicle has electronic or adaptive suspension, verify compatibility before ordering.
This extra check matters because a part can physically bolt in yet still be wrong for ride height, spring rate, or trim-specific features.
When a Quick Strut Makes More Sense than a Bare Strut
A quick strut is usually the better choice when several suspension pieces are worn at the same time. That is common on older vehicles with 80,000 miles or more.
- The strut is leaking or weak and the mount is noisy
- The vehicle has a broken or sagging spring
- You want to avoid using a spring compressor
- You need a faster weekend repair with fewer extra parts
- The car has high mileage and you want a more complete front-end refresh
A bare strut may still make sense if your springs are in excellent condition, you want higher-end dampers, or you are building a setup around OEM or performance-specific components.
Installation Tips After Replacing a Quick Strut
Even though a quick strut simplifies the job, proper installation still matters. Suspension work affects steering, braking, tire wear, and safety.
- Replace struts in pairs on the same axle whenever possible
- Torque all fasteners to factory specification with the vehicle supported correctly
- Reconnect brake hose and ABS wire brackets exactly as original
- Inspect sway bar links, control arm bushings, and tie rods while the suspension is apart
- Get a wheel alignment after installation, especially on front struts
- Listen for clunks on the first test drive and recheck visible fasteners if needed
If the vehicle still sits unevenly, pulls, or makes steering noise after the repair, double-check part number accuracy and inspect nearby suspension components that may also be worn.
FAQ
Does a Quick Strut Assembly Include the Upper Mount?
Usually yes. Most quick strut assemblies include the upper mount because the goal is to provide a ready-to-install unit. Still, check the product listing to confirm.
Does a Quick Strut Come with a Bearing?
Often yes on front strut applications that rotate with steering. Rear assemblies may not use the same type of bearing, so included parts can differ.
Is the Coil Spring Included in a Quick Strut?
Yes, that is one of the defining features of a quick strut. The coil spring is pre-installed on the strut, which helps eliminate the need for a spring compressor.
Do I Need to Reuse Any Old Parts with a Quick Strut?
Sometimes. You may need to reuse or separately buy certain nuts, bolts, sway bar link hardware, or trim-specific brackets depending on the vehicle and brand.
Are Quick Struts as Good as OEM Parts?
They can be, but quality varies. Premium assemblies tend to match factory ride and durability better than budget options, so brand choice matters.
Should I Replace Both Front Quick Struts at the Same Time?
Yes, replacing both sides on the same axle is the best practice. It helps maintain balanced handling, braking stability, and even ride height.
Do I Need an Alignment After Installing Quick Struts?
Yes, in most cases you should get an alignment after replacing front struts. Suspension geometry can change during removal and installation, even if the parts fit correctly.
What Is the Difference Between a Bare Strut and a Quick Strut?
A bare strut is only the damper and requires transferring the spring and related hardware. A quick strut is a pre-assembled unit that usually includes the spring, mount, bearing, boot, and bump stop.
