Bellhousing Bolts: the small fasteners holding your engine and transmission together

Bellhousing bolts clamp the transmission or bellhousing to the back of the engine block, keeping the two cases tightly indexed so the input shaft, clutch and flywheel all stay in line. When they back off or stretch, you get rattle, flex and misalignment right where the drivetrain sees the most load. Anyone who has pulled a gearbox knows the factory hardware is often the first thing you want to upgrade, and a proper set of bellhousing bolts takes the guesswork out of torquing that joint back down correctly.

What we stock

This is a focused category. We carry 4 products across 2 brands: ARP and McLeod Racing. The current in-stock range runs from $38 to $313 — that is what is on the shelf now, not a standing promise. Most of the range is fastener kits; the top of the range is a McLeod Ford aluminum bellhousing that mates a modular engine to a T-56 or Magnum transmission.

How to choose

The split here is simple: are you buying just the hardware, or hardware plus a bellhousing?

  • If your bellhousing is good and you only need fresh fasteners, look at the ARP kits. The ARP GM LS 12pt Bellhousing Bolt Kit uses a 12-point head for socket clearance in tight spots, while the ARP GM LS Hex Bellhousing Bolt Kit uses a standard hex head. Both cover GM LS applications and sit close in price.
  • If you are adapting a Ford modular engine to a T-56 or Magnum gearbox and need the housing itself, the McLeod Ford Aluminum Bellhousing (8580) is the piece for that swap.

Between the two ARP heads, choose on tool access: a 12-point head helps where a hex won't clear, otherwise the hex kit does the same job.

What else you need with it

Bellhousing bolts are one fastener in a larger job, so plan the rest of the drivetrain while you are in there. If you are separating the engine and gearbox, it is a natural time to inspect the clutch components, freshen a worn assembly with clutch rebuild kits, and check the flywheels that live in this same space. For the linkage and shifter side, see shift components and clutch levers. Further back in the driveline, browse differential components for the axle work. The full Drivetrain section ties all of these together.

Fitment help and ordering

Only the Ford application is called out by name in this range, so match the bolt kit to your specific engine and transmission before you order. If you are not sure which set fits your combination, call our fitment team at 813-535-5801 or reach us through contact us. All orders ship free, and Affirm financing is available if you are building the whole driveline at once.
