21. The cam followers aid in noise reduction, dampened vibration, shock absorption and the carrying of axial load. 22. The landing gear is tubular steel, with automotive valve springs and rubber hose inside, for shock absorption . 23. Starting in 1968, a number of units were equipped with pneumatic shock absorption and passive tilting systems. 24. The shock absorption seemed needlessly harsh, too, though that is no fault of the cab forward design. 25. The pastern is vital in shock absorption . 26. The hardness of the tires and the minimalist approach taken to shock absorption made the cars strikingly uncomfortable. 27. The shoe provides stability, emphasizing a smooth feel during a run while retaining movement control and shock absorption . 28. Rubber discs, as well as spring steel, around the legs allow for compression and shock absorption on landing. 29. Early Citabrias were fitted with a steel tube main gear which uses an oleo strut for shock absorption . 30. Wrestling is conducted on a padded mat that must have excellent shock absorption , tear resistance, and compression qualities.
