Best Coil Spring Compressor for Struts (2026)

Compare the picks

21 October 2026

How we scored them

Each compressor is scored on performance, build, value, safety and warranty, using only what the listing publishes. Stated safety hardware and stated capacity earn the most; nothing stated on safety or warranty means no points there.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

Buying guide: best coil spring compressor for struts

Hydraulic vs threaded vs internal

The VEVOR hydraulic unit is the shop press style: a 4.5 ton hydraulic jack with 1 ton of rated compression force, two clasps for different spring sizes, and a 12.6 in compression stroke with 8 positioning holes. The VEVOR 2-pc set and the ReluxGo are threaded pairs that hook onto the spring and compress with a socket on the hex bolt. The OTC 7045B is an internal compressor for front coil springs between the upper and lower control arms. The Branick 7600 is the bench unit with a heavy-duty acme thread. Hydraulic is fastest; threaded pairs are portable; internal fits where pairs cannot reach.

Safety: the non-negotiable

Three listings state real safety hardware. The VEVOR hydraulic lists a 39.4 in extended safety chain to secure the springs, a stable locking mechanism, a safety tongue on the clasp, an H-shaped stable base and pre-drilled holes to anchor it to the ground. The VEVOR 2-pc set lists adjustable safety brackets fitting 8.6 to 12.2 in springs and a safety locking ring on the clamp mouth. The ReluxGo lists locking pins for additional security. The OTC lists four self-aligning plates for load distribution. The Branick lists nothing. A spring compressor without stated safety hardware is a gamble, not a bargain.

Capacity and vehicle fit

Stated capacity runs 4.5 ton jack capacity with 1 ton compression force on the VEVOR hydraulic, and 2,646 lb on the VEVOR 2-pc set. The other three state no capacity. The ReluxGo states MacPherson struts on small and medium cars with a 10.6 in range. The VEVOR hydraulic fits sedans, SUVs, off-road vehicles and pickups with clasps for 4.3 to 5.1 in and 5.5 to 6.7 in springs. The OTC fits most late-model rear wheel drive domestic vehicles with coil springs between the upper and lower control arms, and explicitly does not work on Mercedes-Benz vehicles. Match the listing to your suspension before ordering.

Weight and portability

Listed weights run from 8.53 lb on the ReluxGo and 10 lb on the VEVOR 2-pc set, through 11.1 lb on the OTC, to 57.3 lb on the VEVOR hydraulic and 98 lb on the Branick. The threaded pairs travel to the car; the hydraulic and bench units stay in the shop. For strut work at home, the portable pairs do the job without a dedicated bay.

Warranty

Only the OTC states a warranty, and it states two that conflict: lifetime limited warranty in the bullets, 1 year manufacturer in the table. The other four state no warranty. A stated warranty on a tool under this much tension is worth having, even a conflicted one.

Greasing and technique

The VEVOR 2-pc set is the only listing that states technique: grease the threaded rod before operation, compress and release alternately on both sides to keep the length even, use both hands, and do not use impact wrenches. Those four instructions are the difference between a controlled compression and a tilted, binding mess. The other threaded listings state no technique, but the physics is the same: even, greased, by hand.

One job vs shop use

For a single strut replacement at home, the portable pairs win: the ReluxGo at 8.53 lb and the VEVOR 2-pc set at 10 lb do the job and store in a case. The VEVOR hydraulic at 57.3 lb and the Branick at 98 lb are shop furniture. Buy the tool for the number of jobs ahead of you, not the number you wish you had.

What the listings leave unstated

Three of the five state no capacity at all, which for a tool rated in tons and pounds is a real gap. The OTC’s warranty contradicts itself between bullets and table. The Branick states no safety hardware, which on a spring compressor is the most important unstated thing in this lineup. Where listings are silent or conflicted, the score reflects it.

Drive, steel and plate sizes

Check the drive before the first job. The ReluxGo turns on a 1/2 inch square drive or a 13/16 inch hex socket, and the VEVOR 2-pc set takes a 3/4 inch socket on the hex bolt at the bottom of the threaded rod; the VEVOR set’s compressive stroke is 11 inches. Steel is stated on three: the ReluxGo uses drop-forged hooks and heat-treated 45# steel, the VEVOR 2-pc set is high-hardness #45 steel with forged, nickel-coated clamps, and the VEVOR hydraulic pairs a Q235 reinforced steel column with ductile cast iron clasps and a leak-proof pump. On the OTC, fit is about plate size: two 3-3/8 inch ID plates and two 4 inch ID plates, case-hardened and self-aligning. The Branick takes yet another approach, with multi-position hooks and no adaptors required. If your sockets, springs or plates do not match what the listing states, the compressor does not fit the job, whatever its capacity says.

Frequently Asked Questions

Can I use an impact wrench on a spring compressor?

The VEVOR 2-pc set explicitly says impact wrenches are not recommended, and instructs greasing the threaded rod, alternating sides, and using both hands. The other listings state no wrench guidance. Follow the listing on the tool you buy; an impact wrench on a threaded rod is how threads get destroyed.

Which compressor is for MacPherson struts?

The ReluxGo states MacPherson struts and springs on most small and medium cars. The VEVOR hydraulic states strut springs and shock absorbers across sedans, SUVs and pickups. The OTC is for front coil springs between control arms, not struts. Match the tool type to the suspension.

What safety features should a spring compressor have?

As stated here: a safety chain, locking mechanisms and a safety tongue on the VEVOR hydraulic; adjustable safety brackets and a locking ring on the VEVOR 2-pc set; locking pins on the ReluxGo; self-aligning plates on the OTC. If the listing states none, as the Branick does, that is a stated absence worth weighing.

Which of these has a warranty?

Only the OTC, with lifetime limited warranty in the bullets and 1 year manufacturer in the table. The conflict is in the listing itself; either way it is the only stated warranty here.

Will the OTC 7045B fit my car?

The listing states most late-model rear wheel drive domestic vehicles with coil springs between the upper and lower control arms, and explicitly excludes Mercedes-Benz vehicles. If your car is front wheel drive or a Mercedes-Benz, the listing says no.

How do I keep both sides even when compressing?

The VEVOR 2-pc set instructs compressing and releasing alternately on both sides to maintain consistent compression length, with the threaded rods as parallel as possible. The ReluxGo’s Acme rods and the OTC’s self-aligning plates serve the same goal. Even compression is what keeps the spring from tilting and rebounding.
