Push Through Trailer Wheel Center Caps 84mm / 3.31in - Chrome Set of 4

Our review of these push through trailer wheel center caps finds them best suited for owners who need a simple, cost-effective cosmetic upgrade to 84mm / 3.31in rim bores. The biggest reason to buy is straightforward: they are easy to install and deliver a clean chrome look without tools. Fit and finish are the primary selling points for people restoring or refreshing trailer, truck, or RV wheels where the center bore matches the 84mm measurement.

Key Features

• Exact fit: Push in closed diameter of 84mm and flange diameter of 92mm give a precise fit for compatible 3.31in rim bores.
• Chrome plated finish: High-quality chrome plating provides a mirror-like appearance that improves wheel aesthetics.
• Deep internal height: Internal height of 72.8mm ensures the cap seats fully into the center bore for a secure look.
• Simple installation: Push-through design means the caps can be installed by hand with no tools or adapters required.
• Vehicle compatibility: Sized for 3.31in / 84mm trailer, truck and RV wheel rim bores, including some Cragar wheels and older trucks.
• Value pack: Comes as a set of 4, which covers a single axle or a matching set for one vehicle.

Who It's For

This set is aimed at owners of trailers, trucks and RVs with 84mm center bores who want a quick cosmetic upgrade or replacement for missing center caps. It suits classic truck owners, DIY restorers and anyone using Cragar-style wheels who needs a uniform chrome center cap set.

People who need corrosion-proof stainless steel parts for marine environments or those requiring a branded OEM center cap with logos should look elsewhere. Also, confirm your rim bore measures 84mm / 3.31in before ordering, since this design is purpose-sized and not universally adjustable.
