Turn-Key Solution — No OE Clips/Brace Needed
Unlike factory indicators that rely on expensive and frequently unobtainable OEM plastic retainers, these assemblies are engineered as a complete standalone fix. You do not need to hunt down rare hardware; everything required to mount the assembly securely to your fender is included in the package.
Overview & Build Process
Genuine factory 1M side indicators are permanently discontinued or subject to indefinite backorders. To solve this platform headache, these units are hand-fabricated using M-platform donor assemblies to replace obsolete OE part numbers 51138051601 and 51138051602.
These are custom, hand-shaped ABS assemblies crafted to replicate rare 1M side indicators. Paired with an included automotive bedding kit for a rigid, flush install. Built specifically for custom, widebody, and clone conversions.
Each set is individually trimmed, shaped, and test-fitted on a dedicated bench jig prior to packaging.
Installation & Bedding Kit (Included)
Because subtle curvature tolerances exist across OEM steel and aftermarket composite 1M fenders, we supply a complete closed-loop bedding kit for an exact, flush fit:
OEM-Spec Victor Reinz Reinzosil RTV Silicone: A brand-new, factory-sealed tube of professional-grade German RTV silicone sealant. Applying a continuous bead along the inner mounting flange cushions the housing, pulls it down flush to eliminate panel gaps, dampens road vibration, and blocks water intrusion.
Surface-Prep Alcohol Wipes: Included to properly degrease the fender recess for maximum adhesive bonding strength.
Heavy-Duty 8-Mil Nitrile Gloves: Diamond-textured, latex-free, and powder-free gloves to keep your hands and paint clean during application.
100% Reversible: Cures into a permanent, flexible automotive gasket that will not harm clear coats and peels away cleanly if removed down the road.
