Product Highlights
Forged Steel Body: Unlike cast alternatives, our adjuster body is forged from high-density steel to handle the high-torque stresses of dozer operations without cracking.
Precision Machining: The cylinder and piston are CNC-machined to ensure a tight seal, preventing grease leakage—the most common cause of track tension loss.
Heavy-Duty Recoil Spring: The internal spring is made from high-fatigue resistant steel, designed to absorb sudden impacts and protect your final drive and idlers.
Plug-and-Play Fit: Manufactured strictly to OEM PV340 dimensions. No modifications are needed for installation on D3C or D4C frames.
