Detailed Description

The 10 mm rod, 22 mm tube, 641 mm extended length, and 387 mm compressed length help match the original geometry, while the 685 N force rating provides the support level needed for the specified application. This part cross-references Monroe Shocks & Struts 172286 for the same application.

For buyers searching for a Toyota Previa liftgate strut, rear hatch gas spring, or OE replacement gas shock, this Stabilus 3B-029321 listing provides the core dimensional and attachment details needed for a proper match. The plastic socket connections at both ends are important for confirming interchange before ordering.

Common Replacement Reasons

• Liftgate or hatch no longer stays open
• Rear support drops too quickly when opened
• Original gas strut has lost pressure
• Uneven or weak opening effort on the hatch
• Noise or binding from worn socket connections

Installation Notes

Verify the extended length, compressed length, rod diameter, tube diameter, and plastic socket attachment style against the original part before installation. Confirm the vehicle is a 1991-1997 Toyota Previa and compare the existing strut’s force rating and mounting style to avoid mismatch. If the hatch uses paired supports, inspect both sides for wear so opening effort remains even after replacement.
