• Trucktec: 01.53.001

• Meyle: 034 072 0004

• Precision Smooth-Glide Technology: TinzerMotor utilizes low-friction sliders and specialized industrial lubricants. This ensures the window remains exceptionally easy to crank, preventing the mechanical "stiffening" often seen in budget replacements.

• Reinforced Structural Design: Every unit features thick-walled steel rails and high-tensile fasteners. This prevents the mechanism from rattling or losing alignment, even after years of use on rough terrain.

• Rigorous Reliability Testing:

• Mechanical Cycle Validation: Each design is tested to withstand over 20,000 full-stroke operations, ensuring the crank gears and internal pivot points do not wear out or strip.

• Anti-Corrosion Treatment: All components receive an 8-stage anti-corrosive coating (Salt Spray Tested), protecting the regulator from moisture and road salt ingress within the door cavity.

• OEM Fitment Guarantee: Manufactured to exact 1:1 OEM specifications, ensuring the manual handle spindle and mounting bolts align perfectly with the original door panel.
