Custom Size Worked Flawlessly
Needed a non-standard length. Support team confirmed dimensions quickly. Custom part arrived exactly as specified.

Good Value Direct from Factory
Price is unbeatable compared to local dealers. Took a week to arrive but worth the wait. One sleeve had minor scratches.

Exact Fit for My Komatsu
Ordered the 65x80x70 size for my Komatsu PC200. Fitment was perfect without needing reaming. Steel quality feels solid.
