Abstract: A rebound bumper for a shock absorber includes a first portion formed from a first material having a first spring rate and a second portion coupled to the first portion and formed from a second material having a second spring rate greater than the first spring rate. The first portion and the second portion are configured to fit on a piston rod between a piston and a rod guide assembly of the shock absorber. Also, the rebound bumper exhibits a displacement under load relationship with the first spring rate, the second spring rate, and a third spring rate greater than the first spring rate and less than the second spring rate.

Abstract: A steering damper assembly includes a cylindrical pressure tube defining a working chamber; a piston assembly disposed in the working chamber; a reserve tube extending circumferentially around the pressure tube and defining a reservoir chamber that is radially between the reserve tube and the pressure tube; a base valve fluidly connecting the working chamber and the reservoir chamber; and a piston rod fixed to the piston assembly. The reserve tube includes a cylindrical portion and a bulged portion. The cylindrical portion extends concentrically around the pressure tube. The bulged portion includes a first circumferential section and a second circumferential section, the first circumferential section having a maximum radial distance at most equal to an inner radius of the cylindrical portion, and the second circumferential section having a maximum radial distance greater than the inner radius of the cylindrical portion.
