TRZ Motorsports Billet Faceplate 4130 9" Housing Blank - No Back Brace - 650-209-1
Premium 4130 Billet Faceplate 9-Inch Housing Blank
The TRZ Motorsports Billet Faceplate 4130 9? Housing Blank (Part #650-209-1) is engineered for top-tier race builds that demand precision, rigidity, and lightweight construction. This housing features a pocketed billet faceplate designed for weight reduction, with blind 3rd member hardware holes plus integrated vent and drain ports for clean plumbing and maintenance.
The housing utilizes a 3-piece chromoly shell with a centered fill cap opening and billet axle tube caps that locate tubes internally for accurate placement. TRZ includes an anodized high-grip fill cap with a pre-welded bung, internal housing gussets, ARP studs, nuts, and washers for the 3rd member, and all necessary vent and drain components.
This version is the No Back Brace configuration. Optional back brace choices include a tubular 1-5/8? 4130 back brace or a sheetmetal 4130 back brace, available separately.
Important: This housing is designed for 3.5? axle tubes and measures 50? from tube end to tube end with a centered pinion. It is intended for use with RTV sealant only, not a gasket. Units are typically built to order, with a lead time of 1 - 2 weeks. Signature is required upon delivery.
