Smooth sliding is assured.

Welding heat is the primary cause of slider hardening. The mounting frame and sliders of this model are secured with rivets and bolts to prevent thermal distortion of the metal sliders. Direct welding of sliders is performed only as an auxiliary process to minimize the number of spot welds. For vehicles that require transfer of the original-equipment seat belt buckle to the seat rail, the seat belt buckle stay is fixed with rivets. Smoother slide is achieved by the elimination of distortion due to welding heat.

Four-step height adjustment provided at rear of seat.

The seat height can be adjusted in four steps*1 thanks to the independent mounting frame on the rear and the four bolt holes provided on stays behind the sliders. Because the mounting frame is independent, it can be set to any of four heights or seat angles*2 while reducing the load on the sliders during height adjustment.

*1 Some models (listed in the compatibility table) offer three-step height adjustment.
*2 When the seat is lowered, the tips of the stays behind the sliders may interfere with the floor or mounting frame, limiting the adjustment range. In this case, cut the stays with a grinder or hacksaw.
