ALPHA MOTO Motorcycle Bike Shock Coil Spring Compressor Tool Kit Compatible with Honda Suzuki Yamaha Kawasaki CB KZ XS GS 550 650 750 850 950

I picked this up to compress the springs on my sons 2022 Honda Recon to add the lift kit spacers.It worked out great and fit perfectly.I would recommend this to anyone that has a similar need.

Changed Yamaha shock spring super easy and safe.

Worked perfectly to rebuild my old rusty ATV shocks. Definitely NOT for a car coil spring though.There is room for design improvement, but not terrible, and with a little preparation, these worked great.After reading other reviews about bent tools and these dangerously shooting off the spring unexpectedly, here are some things I did that helped me use them (see attached pics for reference) :-I clamped one compressor in a vice lengthwise which helped stabilize the whole apparatus while working.-make sure the two compressors are 180° apart on the spring (directly opposite from each other). If they aren't exactly 180° apart, they tend to slide around the spring towards each other creating a lop-sided mess that you'll have to undo and start over.-make sure each compressor grabs the same number of spring coils as the other one (for example, don't grip 4 coils on one side and 5 on the other)- once one compressor is clamped in a vice, I used a drill (set to low speed "1" for more torque) with a 3/8 extension (no socket needed since the square 3/8 extension plugs in to the end of the compressor). This made quick work of compressing the spring. I did a little on one side, then a little on the other then repeated, to prevent the spring from over-bowing.- these tools DON'T have a "max length" marking, which is a bit dangerous, as the tool could be completely unthreaded causing the spring to forcefully shoot off the tool, so BEFORE I started any work, I made my own "max" mark with about 3-4 threads still gripping so I wouldn't over loosen the tool with a spring in it.- make sure the threads on the tools are lubed before use too.

Used it to mount a heavier spring on my Ohlins shock. The shock has a remote hydraulic preload adjuster, which along with the different Ohlins spring diameter, made it so the local shop couldn't use any the tools they had to do the work. Ohlins has a compressor, but it is an elaborate and expensive tool. I tried a few automotive type strut compressors but they were all too large. Took a chance on this inexpensive item. With a little care, some friction tape to keep the hooks from slipping on the angled spring coils and an air wrench, it worked perfect! My bike is a sport touring style bike and the spring is a lot heavier than most sport bikes to start with. I went from a 95KG spring to a 100KG spring. You don't realize how stiff these things are until you have it out of the shock body and in your hand. I tried using a regular long handled ratchet wrench to compress the spring. No way. You really need to use this tool with an impact wrench. I used my 3/8s drive air ratchet and it struggled towards the last bit needed to remove the shock collar. Unless you're doing a light spring, consider an impact wrench as part of the cost if you don't already have one. Make sure to lube the threads before using. I gave it 4 stars because it would be nice if the plastic coating the hooks was made of something stickier. The only problem I had was the compressors would slip on the painted angled surface of the coils. A little friction (hockey) tape helped, but you still had to handle with care to prevent slipping. When it slips, you have to remove everything and start over. Just something to be aware off when using.

Ignore the reviews that tell you it is weak and flimsy. I used it to swap to the fat boy spring on my Ohlins HO 047 Mini S36 for my 23 Grom, and it worked perfectly. My only complaint is the paint protectors that they provided couldn't fit to protect the paint, but the tool didn't marr the paint noticibly.

Attempted to use this on a 10.27kg/mm 575lb motorcycle rear shock spring. First off it was very difficult to keep the tools from migrating around the spring. In rotating/moving around the spring, it marred the finish on the spring which is is there to help keep the spring from rusting.The problem came when I was releasing the tension. As you can see the tool on the right bent, flew off and the sides of the jaw shattered and was flung every whereThese tools are definitely NOT meant for today's rear shocked motorcycles, especially ADV bikes. They should rate the tool. That it may work for "lighter" springs.I believe if you have a big spring 4 of these might do the trick OR they could just construct these better..I cannot recommend this tool for monoshock motorcycles with heavy springs probably no more than 8kg/mm if even that...

Bought this spring compressor set for use in replacing the single spring on the monoshock on the rear of my BMW F800ST bike. This tool is almost not up to this job. I'm guessing this tool is really intended for the lighter springs found on dual spring/shock rear motorcycle suspensions like you might find on some Harleys or on older Japanese bikes. At any event, by liberally greasing the compressor threads and the guide housings I got these to work OK and got the job done so I felt the tool earned a three star rating. But it's probably too light duty for frequent easy monoshock disassembly/reassembly or for professional shop work. The metal storage box worked perfectly.

I used it on my atv shocks worked great

tres utile et bien fait

Worked on Yamaha Banshee Front Shocks

perfect for what I needed

The spring compressors do work but barely. They need to be two or three inches longer to work with most ATV coil springs. I really had to crush down the coil springs on my ATV to compress them far enough to get the lock clip off. This makes the coils almost touch each other and it can push severe stress on the metal. If you've got small ATV springs this might work but it barely work on my Yamaha grizzly.
