## Description

2 Truck Upfitters 17" Gas Props (17.1" Extended, 9.9" Compressed, 45 pounds of Pressure ea) for are, ATC, Snugtop, Leer Camper Shell/Truck Cap Rear Door. Measurement Required! Incl 4 Ball mounts!

## Features

- CHECK LENGTHS AND PRESSURE BEFORE ORDERING. THESE DO NOT FIT ALL CANOPY and COVERS! THE MEASUREMENTS ARE FROM CENTER OF BALL MOUNT TO CENTER OF BALL MOUNT, NOT FROM END TO END OF STRUT! SEE PICTURE! Use a measuring tape to measure the door gas strut that you are replacing. Measure from the CENTER of the gas prop head (little plastic end), to the other side. DO NOT measure from the end of the gas prop, your measurement will be too long. Note that most applications allow for 1-5% size variation.
- Truck Upfitters Pair of 45 pound (each) gas struts. 17.1" extended length and 9.9" compressed length. This size of door shock absorber is for tall medium weight rear or side camper shell doors. Each canopy shock has 45 lbs of pressure, for a total of 90 lbs of pressure. Please note that this does not mean that these gas lift shocks can lift something that is 90 lbs. the typical hinged-style door weight for this prop is approx 60-80 lbs, including the weight of the camper shell locks & keys.
- These gas lift cylinders do not fit all camper shell brands / models. Measure your strut from center of socket to center of socket when fully opened & fully closed to get accurate measurement. Please see pictures to determine how to measure. Do NOT measure from end to end. Measurement must be from the center of plastic ball mount on each end of the gas spring lift. Measurement is important to ensure they open properly and get a good camper shell seal against the camper shell gasket when closed.
- Comes with four 10mm ball mounts for alternate 'other than truck camper shell' applications, such as in camper / canopy windoors, RV doors and awnings, boat hatch spring lifts, gas struts for cabinets, storage bed lifts, toolbox struts, etc. These gas shock lift supports CANNOT be compressed by hand. These gas props MUST be installed in the EXTENDED / OPEN position. It is nearly impossible to install them in the CLOSED position. Please refer to the install video for guidance on how to install.
- Equivalent to Suspa # C16-04270 or Stabilus # 1822. These camper shell shocks are compatible with many truck canopy types, including LEER truck cap parts, ARE truck topper parts, Glasstite parts, Century parts, Snugtop replacement parts Astro tops, ATC campers, and many other fiberglass brands that utilize gas shocks / gas springs / gas lift cylinders. Compatible with many gas lift brands, including stabilus, lift o mat, and Suspa. These are OEM quality and perfect fit for your topper!

## Questions & Answers

**Q: lift-o-mat 17" open 12" closed glass camper shell  window alum. frame  numbers on strut are 2944ex   0124n 221/97    5003022812 ?**
A: Hello,
I'm pretty sure these will work. These are 9.9" when closed but that usually doesn't matter as long as it's shorter (rather tahn longer) that the 12" you need. 45 lbs might be a bit much for light aluminum doors unless it's a commercial unit or a heavier door. If they don't work. you can return them, no problem.
Thank you!

**Q: will these replace C1621794 711499?**
A: Not sure about part numbers, I just used extended and compressed length matching up to units they where replacing on truck canopy. Get as close as possible to original units.

**Q: How many lbs will this hold using both uplifters? 90lbs?**
A: These are rated for 45lbs each so two will hold 90lbs.  I’d get 55lb strut if u are needing to support 90lbs. Remember you are only supporting half the weight since the hinge I supporting the other half.

**Q: question for truck upfitters. you reccomended i use the 45 lbs for my snug top as apposed to the 38lbs. the ones on it now are 16". will 17" work?**
A: they are working great on my shell. the back on mine is taller, so a larger glass
38lbs would probably be fine also

    Great replacement for my worn out ones
  

*by V***V on Reviewed in the United States on June 24, 2024*

Snapper right on, easy to install. Firm support but easy to pull down my topper glass

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Just as advertised, easy install, and great to have the auto lift working again.
  

*by D***M on Reviewed in the United States on January 11, 2023*

Popped off the old, snapped on the new...took about 10 min. max. Love having my canopy window operational again...tired of trying to load and duck the window on some days, and being surprised when it held up due to a favorable wind. Reasonable price, but worth twice the price in what it does.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Strong enough I only had to replace one
  

*by 7***O on Reviewed in the United States on September 7, 2024*

Both pistons were bad and I remember replacing both a long time ago and it was trying to pull the hing off my metal canopy door.  This time, just replaced one and it is perfect and I have a spare.
