TRZ Motorsports Billet Faceplate 4130 9" Housing Builders Kit
Racing Use Only, Not Legal for Road Use
Unwelded chrome-moly 9" housing builders kit from TRZ Motorsports, for fabricators who want to build their own housing on 3.5" axle tubes. The billet faceplate and tube caps locate the tubes before you weld anything. Choose no back brace, a round tube back brace or a 4130 sheet metal back brace.
What's included
- Pocketed billet faceplate with blind third member holes and integrated vent and drain ports
- Billet axle tube caps
- 3 piece chrome-moly rear shell with a centered fill cap opening
- Anodized high grip fill cap with weld bung
- 2 internal housing gussets
- ARP third member hardware: 10 studs, nuts and washers
- 1 drain plug and 1 vent
What to know
- Designed for 3.5" axle tubes with a centered pinion
- The tubes and caps can be fully welded to the faceplate before the shell is installed. The caps and shell are then fitted to each other
- Built for RTV sealant, not a gasket. If you use a gasket, shims of similar thickness are required
- Back brace options: none, a round tube 1-5/8" 4130 blank with housing patches and gussets, or 4130 sheet metal
