Description

A custom-engineered, heavy-duty upgraded BMW WINDOW CLIP (Sliding Piece) designed for BMW 3-Series E36 (Coupe, Sedan, Compact, Touring), 5-Series E34, 7-Series E32, as well as Z3 and Z4 models The fragile factory lattice design is replaced with a solid, reinforced monolithic plate block. This drastically increases structural strength, preventing the slider from cracking under heavy window regulator tension and removing the common weak points of the stock part. It keeps the window glass perfectly level without twisting or binding during window operation. Features: 🛡️ Heavy Duty Reinforcement: Solid block redesign eliminates factory weak spots and distributes stress evenly along the window track. 📐 Perfect OEM Fitment: Central socket matches the original 11.5mm ball joint diameter to snap tightly onto the regulator arm. 🔩 Metal Spring Compatible: Features integrated side slots precisely designed to accept and lock your stock metal retaining spring clip. 🚗 Wide Compatibility: Fits perfectly on E36 (all body styles), E34, E32, Z3, and Z4 models How to install: 🧹 Remove the door panel, completely clean out the old hardened grease and broken plastic shards from the metal window rail. 🔒 Pop the newly printed plastic sliding piece onto the metal ball-joint of the regulator arm first, then lock it securely with the stock metal retaining spring clip. 🔲 Apply fresh white lithium or silicone grease to the window channel. Line up the regulator arms and carefully slide the outer wings of the plastic block into the horizontal metal channel on the bottom of the door glass.
