Stabilus Liftgate Lift Support P/N:4B-816941
Hold your hatch open smoothly and steadily with the Stabilus Liftgate Lift Support 4B-136715 (also written 4B136715), a 19.82-inch gas-charged lift support with dynamic speed control. It drops in as a direct-fit replacement for the 2010-2015 Toyota Prius and the 2012-2015 Toyota Prius Plug-in, supporting the liftgate as it opens and holding it in the raised position.
This is Stabilus' Lift-O-Mat design, which uses a longitudinal groove — a velocity manifold pressed into the tube wall — to let gas flow around the piston with extension speed and damping engineered for this application. The groove profile narrows toward the end of the stroke for a gentle, controlled stop.
Lift supports wear as a pair, so for best results replace both sides together. Signs a support may need replacing include a liftgate that drifts down, opens slowly, or no longer stays up on its own.
Which vehicles does the 4B-136715 fit?
It's a direct-fit replacement for the 2010-2015 Toyota Prius and the 2012-2015 Toyota Prius Plug-in. See the Buyer's Guide tab to confirm your vehicle.
What does this lift support do?
It's a gas-charged support that helps raise the liftgate and holds it open, using dynamic damping to control the opening speed for a smooth, non-jerky motion.
Should I replace both lift supports at once?
For best results, replace them in pairs. Supports typically wear at a similar rate, so changing both together gives more balanced, consistent liftgate operation.
How long is this lift support?
This lift support measures 19.82 inches, matching the Lift-O-Mat design engineered for the listed applications.
What are signs my lift support may be failing?
Common signs include a liftgate that drifts down on its own, opens slowly, feels heavy, or won't stay in the raised position. Diagnose the cause before replacing.
