The 7 Best Strut Compressors
Updated by · How we research
Seven strut spring compressors compared, from hook pairs to caged shop frames, on spring range, safety and warranty. The Branick 7600 leads for home shops. When users buy our independently chosen editorial choices, we may earn commissions to help fund the Wiki.
Many strut jobs don't need a spring compressor at all, because a complete strut assembly arrives with the spring already fitted. When you do reuse a spring, the tool holds back enough force to injure, so how it grips the coil matters more than speed. These picks run from inexpensive hook sets for one weekend job to caged frames for busy shops.
Editor's Notes
October 26, 2026, by Ezvid Wiki Admin:
The Branick 7600 keeps the top spot. A caged upright frame is still the safest way to squeeze a spring, and Branick still builds this one. The OTC 6494 Clamshell and the Lisle 62300 stay too. New picks cover what home mechanics ask about most: the OEMTOOLS 25553 hook set with latches, a low-cost Orion Motor Tech set, a VEVOR fork kit and a VEVOR hydraulic stand.
We dropped the Jacktech SK-3000 because we couldn't confirm a current listing, the OTC 6637 Strut Tamer II Extreme for its price and weak owner record, and the ABN 9210, BestEquip Three-Ton and Shankly B1025 because of availability concerns. The OEMTools 25550 and Powerbuilt 648627 were replaced by newer models.
No lab has compared spring compressors, so the deciding evidence was Branick's and OTC's own spec pages, the fork and clamp ranges VEVOR publishes, and long mechanic forum threads weighing caged frames against hook sets.

Removed the 8milelake SZ6915 in favor of the Lisle 62300.
We felt that the Lisle 62300 should be included given that it is one of the safest strut compressors available. Removing coils is unnerving precisely because you know that jawed compressors can easily slip off a coil, especially if you don't tighten both sides evenly. Jawed models like the OEMTools 25550 use pins to keep the coil in the grooves but this is designed to fit loosely as opposed to the Lisle, which can be tightened down over the coil very snugly. For any of the threaded compressors to work, you should grease the threads to prevent binding and to allow for smooth operation and extend the life of the tool. Make sure you get the right model for the cars or trucks you'll be working on. Full-sized trucks use thick coils that may not fit into the grooves of some compressors once the pin is extended. You should not operate the tool unless you can fully extend the pin because otherwise there is nothing that would interfere with the spring causing serious damage if it slips.
Wall-mounted strut compressors are the quickest and easiest to use. The Branick 7600 and the Jacktech SK-3000 rank highly because they use universal hooks so they don't require swapping adapters and they are highly adjustable to accommodate most coil sizes including most width and height variations.

Without the proper equipment, installing or removing struts is practically impossible, not to mention extremely dangerous. Even when using one of these purpose made tools it is important to follow the manufacturer's directions and never exceed the rated capacity, as doing so can result in injury. If you have an automotive shop, the wall-mountable Branick 7600 and OTC Tools 6637 Strut Tamer II Extreme, or floor-mountable Jacktech SK-3000 are your best options. They can all handle light- and heavy-duty spring coils, so you won't have an issue whether your next client pulls up in a Prius or Ram 2500. Of course, these industrial-quality models are pricey, so the home mechanic may want to look at some of the more affordable options. Despite each unit being capable of producing over 6,000 pounds of crushing force, the hydraulic-assisted BestEquip Three-Ton is one such option. It is an exceptional value and allows even the casual user to compress springs and struts with relative ease. All though slightly more expensive, the OTC 6494 Clamshell also allows you to let something else do the heavy lifting, in this case your impact wrench. If installing struts is a once-every-few-years activity for you, you can get by with one of the manually-cranked options, like the OEMTools 25550, ABN 9210, Shankly B1025, Powerbuilt 648627, and 8milelake SZ6915. These are generally very affordable and small enough for convenient storage.
Special Honors
QSP MSC-1000 QSP, a maker of tire and suspension shop equipment, builds the MSC-1000 strut compressor for busy garages. It runs on an impact wrench, comes with a safety guard and a retention cable as standard, and QSP says it handles any size of spring and strut assembly. It's sold through equipment distributors rather than in retail stores. qsponline.com
Four Ways To Hold A Spring
Guards and chains exist for one reason: to catch a spring that gets loose.
Every spring compressor does the same job: it shortens the coil so the strut's top nut can come off safely. What differs is how it holds the coil, and that decides how much can go wrong.
Hook sets are two threaded rods with a hook at each end. You place them on opposite sides of the spring and tighten each a little at a time. They're cheap and small, and plenty of home mechanics use them for years without trouble, but nothing surrounds the spring if a hook slips. Latches, like those on the OEMTOOLS 25553, or bolt-on clamps, like those on the Lisle 62300, make slipping less likely.
Fork kits swap the hooks for curved yokes that cradle a full turn of the coil. Clamshell tools such as the OTC 6494 close two jaws around the spring and lock them with pins. Upright frames like the Branick 7600 hold the whole strut in a stand with a guard around it. Hydraulic stands add a bottle jack and a safety chain.
Guards and chains exist for one reason: to catch a spring that gets loose. Sealey, a British tool maker, sells a steel cage and chain for its own compressors for exactly that case (PMM).
Match The Tool To The Spring And The Job
Start with the spring. Measure its outside diameter and the thickness of the wire, then check the tool's range. OTC lists 4 to 9 inches of spring diameter and 7/16 to 11/16 inch wire for the 6494; VEVOR's fork kit covers about 2.6 to 8.3 inches across its three forks. Light-truck and SUV coil-overs are stiff and wide, which is where frames like the Branick earn their price.
Then think about how often you'll use it. For one pair of struts, a hook set is enough, and a complete strut assembly, sold with the spring and mount already fitted, skips the compressor entirely. For weekly work, an impact-rated clamshell or an upright frame saves time and nerves.
Check what your car actually has. Strut compressors are for MacPherson struts, where the spring wraps around the shock. Many trucks and older rear-drive cars carry the spring between two control arms instead, and those need a different tool, such as OTC's plate-type 7045B. Coilovers, air springs and aftermarket lift springs are their own case: Branick says the 7600 is not for factory lift-kit springs, so follow the spring maker's instructions.
Safe Use, Step By Step
Read the tool's instructions before the first job, and inspect it every time: a bent rod, a cracked hook or damaged threads means it's done. Wear safety glasses and gloves, and grease the threads so they turn smoothly under load.
Seat hooks or jaws on full coils, on opposite sides, gripping the same number of turns. Tighten in small, even steps, side to side, and stop before the coils touch each other. Sealey's instructions add a few habits worth copying: fit a restraining chain, stand to one side while compressing, and test that the spring is loose with a tool rather than your hand before taking off the top nut (Sealey RE300 instructions).
Use an impact wrench only on tools whose makers allow it. OTC rates the 6494 for impact use; VEVOR says to keep impact guns off its fork kit. When you release a spring, back it off slowly and evenly until the tool is fully unloaded. Long threads on Bob Is the Oil Guy show how mechanics weigh speed against safety when they pick a tool.

Frequently asked questions
Do I need a spring compressor to replace struts?
Only if you reuse the old spring. A complete strut assembly comes with a new spring and mount already fitted, so it bolts in with no compressing.
Are cheap hook-type spring compressors safe?
They work when the hooks sit on full coils, opposite each other, and you tighten evenly in small steps. Nothing surrounds the spring, though, so latches, clamps, a chain or a caged frame add a margin.
Can I use an impact wrench on a strut compressor?
Only if the maker allows it. OTC rates the 6494 clamshell for impact use; VEVOR says not to use one on its fork kit. Hook sets are usually meant for hand tools.
Will a strut compressor work on coilovers or lift springs?
Not always. Branick says the 7600 is not for factory lift-kit springs, and coilovers usually have their own adjusters. Follow the spring maker's instructions.
What if my car's springs sit between the control arms?
Then you need a different tool. Strut compressors are for MacPherson struts; springs that sit between the control arms take a plate-type compressor such as the OTC 7045B.
