  9. Mario Filion


  10. RWES

    They were WAY TO STIFF for my application however they are one of those things that I won’t return but keep around because Ya never know when you may need a good stiff stick!

  11. Luke Ashlocke

    not going to lie these are heaven sent. You see, im a 5’4″ tall, 51 year old man who’s dream is to be a super model. AND NOW, thanks to Apexstone 2pcs 300N/67LB 15inch Gas Spring/Prop/Strut/Shock/Lift Support , I can achieve that goal! You see, i figure the first step in becoming a model would have to be implants. So i got some…. 44 Double J’s!! Hey, if you’re gonna go big, go BIG. Well i almost broke my back 3 or 4 times trying to do simple tasks like jumping jacks or 180 Turn jumps off of a Coolio Round house stacker on my BMX bike. And i obviously had to find a way to save my back, since my implants were so HUGE. Then i happened upon these puppies. And after attaching them to my under-teet area and then to the implant itself via iron chain brackets, I now have the lift i need to save the back i also need, if im ever going to become the supermodel i think i can be. Thanks again, Apexstone 2pcs 300N/67LB 15inch Gas Spring/Prop/Strut/Shock/Lift Support !

  30. KrazePoko

    Works fine! And to the durka durka who complained about no instructions, please delete your app and buy off eBay. 😂😂

  31. shopper

    Used these to prop up a very heavy cover over pool equipment. There are no instructions so it’s a bit tricky figuring out which direction and at what angle they are installed. But they work great.

  32. Ken Bone


  33. Bob

    These parts work well.
    As received one was missing a nut. I bought a nut at my local hardware store.

  34. Mr. H

    Works great for a bed lift to get to the storage area in our RV

  35. Sammi

    Just like the description says, no screws, no instructions, however it’s pretty straight forward to install.

  36. Diane and JIM Meehan,

    Does what it said it would,

  37. Kathrine Francis

    they are a little too strong for a toolbox lid but they open my toolbox lid in a quickness.

  38. wade sampson

    Great product definitely worth the money

  39. ET

    I installed them on a Weather Guard tool box lid. They work better than the manufacturer’s gas strut at a fraction of the cost.

  40. cindy holden

    Unfortunately you don’t get to chose the type of end they come with. Work great. Good regulation of load.

  41. Chris Pope

    Installed these on my tilt trailer for my motorcycle. Trailer bed is quite heavy, wouldn’t stay up due to its weight. But now with these installed, I have no problem lifting it, and it stays up!

  42. NFinn

    Good quality

  43. Henry Milowski

    Very strong easy to instal strong arm

  44. charlie c brown

    Worked great lifts the 70Lbs lid on my wood bin with ease and closes very smoothly

  45. Bruce Backwards

    The weight of my hood is a critical factor. No idea how to figure the correct weight specs to order the support struts(nothing helpful on YOU TUBE). I guessed correctly. Instructions are NON-EXISTENT. I had to figure out by trial & error the mounting points. I can not say any thing about how long these struts will last. I have had them installed about 3 months. I have a 1977 Honda Civic since new and the struts still work. I have had factory struts on a 1979 Honda Accord that didn’t last 3 years, so who knows how long these will last.

  46. Pat

    They are strong. Make sure you use them with a strong material. Be careful with lamented wood.

  47. db

    Adapted these longer struts to my Weathergaurd truckbox . Used the 4 right angle mounts on the top side back to back so theres 4 bolts to the lid to spread the load, (ground off the original ones that bent) and screwed them in with heavy sheetmetal roofing screws. Added a plate of Aluminium to the bottom to extend down and reinforce the original mounting point. Easily raises the lid hands free, have to catch it at the top to avoid previous damage from over extension.

  48. Color

    I do like it, and I installed into a Redwood box ,these lifts are very strong and I really recommended.

  49. G.m.p

    i have ordered these twice. the first set came with L brackets the second set did not

  50. hamid

    Wrong information. Very much harder than it said. I had to put around 100lb to push it in.

  51. CJ

    Just what I wanted and needed.

  52. AC

  53. Andrew Hartington


  54. UT

    I used them to support and Egress Well cover I made for the exterior of my house .Easy to install! Hope it stands up to the weather conditions.

    Use an Apexstone 300 N 15 inch gas spring to support a Egress Well cover I made for the exterior of my house.

  55. 15inch Gas Spring Lift Support

    Excellent product, I’m a senior citizen and had a hard time lifting the storage space under the RV bed in my trailer, I had replaced the trailer mattress with a regular queen and was to heavy to lift, I left the original support and I just added the 15 inch support under it, after installing these lift supports I now can lift my storage compartment with one hand. awesome product and a economical price.

    Apexstone 300N15inch Lift Support well support a heavy bed

  56. James F 68

    Purchased for our travel trailer bed however they might be to stiff for this application. Nice product though and worth the money if you have the need for them.

  57. Yakko

    They work good for the price

  58. Morgan stine

    I bought these to put under a very heavy lid and they perform adequately

  59. Tammy wells


  60. R Valencia

    Very durable

  61. Lucky J

    Very strong, appear to be very well made, easy install.

  62. Cliff B

    These are great, and good for the price when purchased. Very stout. I used as lifts for under bed storage lid in a travel trailer. Used two, probably just needed one.

  63. Craig

    I installed these struts as pictured under a queen bed in my new trailer. I was thrown off a bit by the instructions in the item details as it states to install 4.79 to 5.12 inches from the hinge on the lid. The picture shows just the opposite. I tried it following the instructions, but it didn’t work, so I reversed the install and measured 4.5 inches back from the hinge on the fixed frame under the lid, and it works perfectly, with a max lift of about 50-60 degrees. My bed is a 60 x 75 with a light mattress, but we use a heavy mattress topper, so the 4.5 inch spacing using the pair of struts turned out to be just right. At $20 a pair, I bought a spare set just in case, since I am not sure how long they will last, hence the 3 stars for longevity.

    Use an Apexstone 300 N 15 inch gas spring to hold up a queen bed in my new trailer.

  64. William G.

    Works perfect for the purpose I got them

  65. Mad max


  66. Cashmj

    Purchased these to hold up the door under full size bed in travel trailer. Work great and easy install.

  67. B

    love the price

  68. Josh Brown

    Ordered them to replace the ones in my car top carrier and they work perfect!

  69. Mary

    Product works great for its use. We have proceeded to by additional products in different strengths.

  70. Maite

    I have a trap door that goes to my cellar, and it weighs like 65 lbs. I used these to make it easier for me to open and close it, since I’m down there almost daily, and they are perfect. Having adequate fasteners helps because having the brackets tight against the walls of the objects you attach them to makes sure they function properly.

  71. terryfoster2u

    We’ll know more next year if these will hold up.

  72. Autoboy

    Did the job

  73. George Beer

    Im very satisfied

  74. M. Clement

  77. Edward M. Brosz

  78. carle


  79. Peter4

    These were a good unit they were not as strong as posted I would order a heaver spring than I need My cover weighed 42 LB’S it did not raise up on its own like I taught it would. Once the cover was up the springs would hold it up ok.

  80. Cesar Rosario

    Thank you Perfect parts

  81. Randy B.

    Installed on jeep tj hood to hold open. Works well. Don’t go smaller on force. I installed 2 pieces.

  82. Reviewer

  83. Theresa PRATT

    Great for being Chinese. They work well enough

  84. Christy M

  85. jyanzi k.

    Ordered 100n but too soft. Got another pair of 300n. Installed 1@300n with existing 100n. Worked perfect.

  86. Lesly

    They work great

  87. Dell

    I built a bed with storage under it, the lid where the mattress rests on lifts up to access underneath and these struts are a very important part of it, they make opening and closing a breeze.

  88. roger w bruener

    All good

  89. grumpy grandpa

    installed on the engine lid cover on the boat which is heavy. worked well

  90. Jose Rodrigo Hernandez Rodriguez

  93. Jake Templin

    Great product. Very strong

  94. lapearl

    My husband installed them after some research and they worked out perfectly.

  95. Michael Sosa

    They work great!

  96. Kristin k.

    Well built & super strong.

  97. Maureen Williams


  98. Sebastian Czigler

    Exactly what I expected and worked perfectly

  99. Larry

    Used these for heavy 3″ trap door to crawl space, excellent lift capacity, excellent quality

  100. C

    Great for assisted lift of RV under-bed storage. using two of these to lift 15″ of a queen bed support (storage runs only 15″ into the mattress, along the side of the bed). These likely would not be powerful enough to lift a storage door that is the full size of the bed. But for my purposes, makes lifting the door MUCH easier, and keeps it open when adding/removing items. Only issue is because of the limited mounting space at 15″ deep, these do not let the storage close all the way. Adding a latch on the door is an easy fix though.

  101. Judy M

    As expected and just what I needed

  102. inspector gadget

    Great Product! I ordered the 67lb 2 piece set to hold up a garbage shed lid that I made (1) for each lid, they work like a charm, just a little lift and they go up and stay up , then a little tug and they come down and stay closed. Fantastic!

    Use an Apexstone 300 N 15 inch gas spring to hold up a garbage shed lid

  103. Timothy Town

    Worked well for my boat sun deck

  104. amy o

    I ordered these to help prop open my service window in my food truck. They definitely do the job and I am not worried about them closing on my customers. At first I had thought they were going to be too strong actually but they ended up to be perfect. The brackets that came with this item made attaching them a breeze.

  105. Pija

    I needed these for my home built Camp Trailer, the hatch style door. They worked Perfectly, after I figured the correct placement.

  106. wmblackknight

    working great

  107. Betty KK

    Great exactly what I wanted for my Pontoon sundeck lift. The same size as the ones I took off but with better ends for fastening.

  108. Daniel ponce

    These work out great. Only issue I had was 1 nut was missing from the package. Had to pick it up from Lowe’s.

  109. BeauH

    I put them on an old pick up tool box. They were perfect. Came quickly, and with all of the hardware to put them on. The 67 Lb tension is perfect for holding the toolbox lids up even in high wind and yet they close easily. I am very satisfied.

  110. Love to teach

    Bought these to try and get the bed in our trailer to stay up on its own when accessing the underside storage area. We got a bigger, heavier bed and the original shocks couldn’t hold it up. Hoping these would compensate for the extra weight, I installed them. They do make it easier to lift, but in the end I had to use a stick to hold it up. Seems these were just a bit too little. Regarding the product, it appears to be high quality for the price. The brackets are beefy. This company makes a set of 100 lb each ones that I should have tried. The original shocks in the pics are 20″ long, for comparison purposes. If you actually have something that is light enough for these to work on, I would recommend getting a set. They are definitely strong. I could not compress them by hand. Hopefully my learning experience will be your success story.
