Center Hubs XD Series: Fitment, Wear, and Replacement FAQ

Quick answer

Center Hubs XD Series are the hub that sits between a Vanquish 1.9 or 2.2 wheel and its SLW hub, and they add .100 of offset. If your wheels use an SLW hub and were not built with a milled-in center cap, these hubs fit. Replace them when screw holes strip, the hub face wears thin, or you want to change track width.

Which Vanquish wheels accept Center Hubs XD Series?

They work with all Vanquish Products 1.9 and 2.2 wheels designed for use with an SLW hub. The center hub rests between the wheel and the SLW hub and is attached by the included screws. One exception matters: some discontinued Vanquish wheels had a center cap milled into the wheel face, and those do not use a separate center hub.

• Check that your wheel is an SLW-hub design before ordering.
• Look at the wheel face: a milled-in center cap means no separate hub is needed.
• Keep the included 4-40 x 3/8 SHCS screws with the hubs so you do not mix hardware between wheels.

What does the .100 offset change on a crawler?

The hub adds .100 offset, which pushes the wheel outward from the axle. That wider track can help body and link clearance on some builds, but it also changes scrub radius and how the tire contacts the terrain. If you are chasing a narrower footprint for tight lines, this is the wrong direction; if you need clearance, it is a direct fix.

How do I know a hub is worn and needs replacing?

Inspect the screw holes first. A hub that has been run loose will oval the holes, and reusing it lets the wheel shift under load. Next check the hub face where it meets the SLW hub; repeated tightening can crush or polish that surface. Finally, spin the wheel and watch for wobble that is not coming from the tire or foam.

• Stripped or ovaled screw holes: replace, do not retap.
• Visible thinning or a dished face: replace before it cracks.
• Wheel wobble after re-torquing: isolate the hub before blaming the tire.

What is included, and what tools do I need?

Each set includes 2 center hubs and 13 4-40 x 3/8 SHCS screws. You need a hex driver that matches the screw head and a clean work surface so the small hardware does not disappear. Do not overtighten; snug is enough to seat the hub against the wheel and SLW hub.

XD Series hub FAQ

Will these fit my non-Vanquish wheels?

The catalog states they work with all Vanquish Products 1.9 and 2.2 wheels designed for use with a SLW hub. Fitment on other brands is not stated, so treat it as unverified. Stick to Vanquish SLW wheels unless you can test-fit first.

Can I run these on wheels with a milled-in center cap?

No. Some discontinued Vanquish wheels had a center cap milled into the wheel face, and those do not use a separate center hub. Inspect the wheel face before ordering.

How often should I check hub screws?

Check them after the first few runs and again after any hard impact. Loose screws are what oval the holes and turn a cheap part into a wheel-damaging one. Snug, not gorilla-tight.

Product facts

• Center Hubs XD Series: The set includes 2 center hubs and 13 4-40 x 3/8 SHCS screws. Two hubs cover one axle pair, and the screw count gives you spares for a full wheel set if you are careful.
• Origin Body Detail Set: The Origin Body Detail Set is an injection molded nylon replacement detail set that includes a radiator and fans, grille, light buckets, and interior and body detail accessories. If you are already pulling wheels and hubs for maintenance, this is the kind of small detail part that is easier to install while the body is off.
