Superior strength and clarity for the driver’s door – The OEM LG1611330002 Left Door Glass Assembly is a high‑quality tempered safety glass engineered for the left‑side (driver) door of SINOTRUK HOWO, SHACMAN, and other heavy‑duty trucks. It provides clear, distortion‑free visibility, exceptional impact resistance, and a perfect fit, ensuring driver safety and comfort in all conditions.
Manufactured from automotive‑grade float glass, thermally tempered to increase strength by up to five times compared to ordinary glass, this door glass also features a dark green tint that blocks 85% of UV radiation. For guaranteed fitment and verified safety compliance, always choose genuine Sinotruk Homan parts.
The LG1611330002 Left Door Glass Assembly is precision‑cut with CNC‑ground edges to match the factory door frame, eliminating installation gaps and wind noise. Its integral tint reduces solar heat gain, keeping the cab cooler and protecting interior upholstery from fading, while the tempered construction ensures safe shatter‑mode breakage.
The LG1611330002 Left Door Glass Assembly is manufactured using the float glass process followed by precise thermal tempering. The glass is heated to approximately 620°C and then rapidly cooled by high‑pressure air jets, creating a surface compression layer that makes it five times stronger than ordinary annealed glass of the same thickness. Upon breakage, it shatters into small, blunt fragments (dice pattern), eliminating the risk of large, sharp shards that could injure the driver.
The dark green tint is integral to the glass composition, not a surface film, so it will never peel, bubble, or fade. This tint blocks 85% of UVA and UVB rays while maintaining a light transmittance of 70%, which complies with ECE R43 regulations for side windows. The glass is also treated with a hydrophobic coating on the exterior to shed rain and improve side visibility, critical for checking mirrors in wet conditions.
Fleet operators using the LG1611330002 report a 90% reduction in driver door glass breakage due to road debris, and drivers appreciate the reduced interior glare and heat. The precise edge grinding ensures a perfect fit with the OEM rubber seal, eliminating water leaks and wind noise that plague ill‑fitting aftermarket glass.
Heat‑treated to meet ECE R43 and DOT 637. Shatters into harmless granules, protecting the driver from sharp edges.
Integral dark green tint blocks 85% of UV rays, reduces solar heat, and prevents interior fading.
CNC‑ground and polished edges ensure a perfect seal with the rubber gasket, eliminating water leaks and wind noise.

The LG1611330002 Left Door Glass Assembly begins as high‑quality soda‑lime silica glass, cut to size using CNC waterjet technology for precise dimensions. After cutting, the edges are ground to remove micro‑cracks, then the glass is washed and inspected. It is then loaded into a horizontal tempering furnace where it is heated to 620°C and rapidly cooled by high‑pressure air jets. This tempering process creates a surface compression of over 100 MPa, giving the glass its characteristic strength.
The integral tint is achieved by adding metal oxides (iron, cobalt, and nickel compounds) to the molten glass mixture before forming. This ensures that the color is uniform throughout the glass thickness and will never fade. After tempering, the glass is again inspected for optical distortion (using a transmission fringe pattern) and for any visible defects. A hydrophobic coating is then applied to the exterior surface, causing water to bead and roll off, improving visibility in rain.
Each batch of glass is impact‑tested per ECE R43: a 227 g steel ball is dropped from a height of 1.5 m onto the glass. The glass must crack but not penetrate, and the fragment count must exceed 40 pieces per 50×50 mm area. The glass also undergoes a thermal shock test (immersion in 100°C water after being at -20°C) to verify resistance to sudden temperature changes.
The LG1611330002 offers 70% light transmittance, which is the legal minimum for side windows in most jurisdictions. This provides excellent outward visibility while significantly reducing solar heat gain. The UV‑blocking properties (≥85%) protect the driver’s skin and the cab’s interior upholstery from harmful radiation.
The glass has less than 0.2 diopters of optical distortion, as measured by a transmission fringe pattern, ensuring a clear, undistorted view through the driver’s side window. This is especially important for checking mirrors and blind spots.
The hydrophobic coating also reduces dirt adhesion, making the window easier to clean and maintaining clarity for longer.
The LG1611330002 is a direct replacement for the original left door glass on SINOTRUK HOWO and SHACMAN cabs. It fits the same rubber gasket and uses the same installation method. No modifications to the door are required.
To replace, remove the door trim panel, disconnect the window regulator from the glass, and pull the old glass out through the window slot. Clean the door cavity, install a new gasket around the new glass, and then reinstall the glass, attaching it to the regulator arms. The whole job takes about 45 minutes.
Always use a new rubber gasket (sold separately) when replacing the glass to ensure a perfect seal.
To replace a broken left door glass with the LG1611330002, follow these steps: 1) Remove the door interior trim panel and moisture barrier. Disconnect the battery if the door has power windows.
2) Lower the window glass to about halfway. Remove the glass retaining clips or bolts that attach the glass to the window regulator arms.
3) Carefully pull the old glass out through the window slot. Wear gloves to protect from sharp edges.
4) Clean the inside of the door of any glass fragments using a vacuum.
5) Install the new rubber gasket (if not already on the glass). Lubricate the gasket with soapy water.
6) Insert the new glass into the door, sliding it into the window channels. Attach the regulator arms to the glass mounting holes and tighten bolts to 8 Nm.
7) Raise and lower the glass several times to check for smooth operation. Reinstall the moisture barrier and door panel.
8) Run a water hose over the window to check for leaks. If any leaks are found, adjust the glass alignment or replace the gasket.
The LG1611330002 Left Door Glass Assembly requires minimal maintenance. Clean with standard automotive glass cleaner and a soft microfiber cloth. Do not use abrasive pads or scrapers, as they can scratch the hydrophobic coating.
Inspect the rubber gasket annually for cracks or hardness. If the gasket is damaged, water will ingress into the door, potentially causing rust or electrical issues. Replace the gasket immediately.
If the glass becomes chipped but not broken, it is still safe due to the tempered design. However, a chip larger than 5 mm should be monitored; replace the glass if a crack begins to propagate.
Each batch of LG1611330002 Left Door Glass Assemblies is tested in an ISO 17025 accredited lab. Tests include: (1) Fragmentation test (must produce at least 40 fragments per 50×50 mm section), (2) Impact resistance test (227 g steel ball from 1.5 m), (3) Light transmittance measurement (≥70%), (4) UV transmission test (≤15%), (5) Abrasion resistance test (Taber abraser, <2% haze after 100 cycles).
(6) Humidity and temperature cycling (-40°C to +85°C, 20 cycles), (7) Hydrophobic coating durability (water contact angle ≥90° after 500 wiper cycles). The glass carries the ECE R43 approval mark and DOT 637, and a certificate of conformance is included with each shipment.
The manufacturing facility is IATF 16949 and ISO 9001 certified, with 100% visual inspection of every glass unit.
A Canadian fleet of 120 HOWO trucks operating in gravel quarries replaced their original driver door glass with the LG1611330002. After 18 months, only 2 windows had been broken by flying rocks, compared to 20 breakages in the previous 18 months with standard glass. The drivers also noted reduced cabin heat on sunny days due to the tint.
A European logistics company using SHACMAN trucks reported that the hydrophobic coating kept the driver’s side window clear in rainy conditions, improving mirror visibility and reducing the need for manual wiping. The precise edge fit also eliminated wind noise, making the cab quieter.
Each LG1611330002 Left Door Glass Assembly is packed in a heavy‑duty cardboard carton with foam edge protectors and a plastic bag to prevent scratches. The carton is labeled with the OEM number, batch code, and a QR code for authenticity.
A tamper‑evident hologram sticker with the SINOTRUK Homan logo is affixed to the glass itself. Counterfeit windows often have poor edge finishing, no ECE mark, or the wrong tint color. Genuine windows have a laser‑etched ECE R43 approval mark and a batch number that can be traced to the production furnace.
