Conversions: change your bolt pattern, stud setup or wheel fitment without guesswork

The parts in the conversions category exist to bridge a gap between what your hubs give you and what you actually want to bolt on. That covers three real jobs: swapping a hub to a different lug count, changing how a wheel clamps to the hub, and running a machined wheel that already fits a specific pattern. If your car came from the factory with the wrong bolt pattern for the wheels you're chasing, or you want to drop the studs your torque wrench likes, this is where you start.

A 5-lug conversion hub replaces the original hub so a 4-lug car can run 5-lug wheels - a common move on older platforms. A bolt-to-stud conversion swaps the original lug bolts for pressed-in studs, so you're threading nuts onto studs instead of fighting bolts through the wheel while holding it up. Both change how the wheel mounts, so both need matching hardware.

What ThreePiece stocks in conversions

There are 18 products in this category right now, spread across three brands: QuadBoss (10 in the sample), H&R (6), and ISR Performance (2). Current pricing runs from $28 to $344 for what's in stock - that's the live range, not a standing offer.

How to choose

Start with the job. If you only need to change hardware, the H&R bolt-stud parts are the cheap, low-effort path - but check your thread pitch (these are M14 x 1.5) and shank length against your setup before ordering. If you need a different lug count entirely, that's hub-level work: the ISR Performance kits are hub-specific, and note they're sold as single hubs, so a full axle needs a pair. The QuadBoss wheels are the opposite end - a finished wheel already drilled to a pattern (4/156 or 4/137), so match that to what your machine actually is.

Fitment data is limited here: only 2 of these products carry explicit vehicle fitment, both for the Nissan 240sx, 1989-1994. Everything else is defined by thread, length or bolt pattern rather than a vehicle list, so read the spec in the product name.

What else you need

Conversions rarely go on alone. Pair studs with matching lug nuts, or check lug bolts if you're keeping the bolt setup. If a hub swap doesn't get you the clearance you want, look at wheel adapters and wheel spacers. New wheels also want center caps. Browse the full wheel accessories section for the rest.
