  • Targeted gm ls engine fitment: this thermostat housing is precision-engineered for use with general motors ls series v8 engines, providing an exact fit for all ls1 and ls2 platforms (excluding ls3 variants)
  • Premium billet construction: cnc-machined from robust 6061 t6 billet aluminum, the unit is treated with a resilient black anodised coating and features a 1.5-inch (38.1 mm) outlet diameter to match factory radiator hose specifications
  • Straight-up swivel design: it incorporates a unique "straight-up" (vertical) neck alignment combined with an integrated swivel mechanism, allowing builders to route plumbing vertically out of the water pump for specialised clearance profiles
The cal custom thermostat housing is an aftermarket solution for general motors ls1 and ls2 configurations—while excluding ls3 platforms—this component replaces the factory water outlet with a cnc-machined 6061 t6 billet aluminum assembly. Its standout feature is a "straight-up" neck orientation paired with a swivel base, offering a vertical exit path that can be rotated to clear tight frame rails, steering linkages, or forced induction plumbing. Coated in a black anodised finish, the housing retains practical serviceability by matching standard factory-size 1.5-inch (38.1 mm) radiator hoses for a trouble-free integration.
