🚪 Top-of-the-Line Gas Props for Snugtop Leer Camper Doors & Weatherguard Toolboxes – 2 Truck Upfitters 12" (12.2" ext, 7.5" comp, 40 lbs each) + 4 Included Ball Mounts – Measurement Required! Review

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 (2 total) of 40 pound (each) gas struts. 12.2" extended length and 7.5" compressed length. This size of door shock absorber is for tall medium weight rear or side camper shell doors. Each canopy shock has 40 lbs of pressure, for a total of 80 lbs of pressure. Please note that this does not mean that it can lift something that is 80 lbs. the typical hinged-style door weight for this prop is approximately 50-70 lbs, including the weight of the camper shell locks and 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.
