Our aftermarket replacement Komatsu XS series straddle adapter and XS series corner adapter are strictly manufactured to OEM dimensional and metallurgical specifications for direct interchange.

Our aftermarket Komatsu XS straddle adapter features dual‑leg straddle design, wrapping around bucket lip, enlarging welding area and distributing digging load across both upper and lower lip faces. This structure greatly reduces risks of weld peeling and adapter shedding which frequently occur on large mining buckets.

Our aftermarket Komatsu XS corner adapter uses reinforced offset‑profile optimized for bucket corner geometry, specially strengthened for lateral scraping, corner collision and uneven side‑load damage. Both of  these Corner adapters go through stress‑relief casting process to eliminate internal porosity and shrinkage defects.
