BILITOOLS Truck Hub Seal Installer Kit — Heavy‑Duty Aluminum 5‑Piece Set for Class 7 & 8, Fits 4‑13/16"–6‑5/16" Hubs

BILITOOLS Truck Hub Seal Installer Kit is a five-piece, heavy-duty aluminum driver set engineered to seat axle hub seals on Class 7 and Class 8 trucks quickly and without damage.

When working on heavy trucks, installing axle hub seals accurately matters for uptime and component longevity. This kit provides a matched set of drivers and a handle extension so you can press seals squarely into hubs ranging from 4-13/16" to 6-5/16" without removing brake drums. Built from aircraft-grade aluminum, the tools avoid marring bearings or housings and reduce the chance of seal distortion that can cause leaks.

How does this kit prevent damage during seal installation?

The drivers are machined from high-strength aluminum to deliver solid, even force without the hardness of steel that can nick housings or bearings. Each driver surface is sized to make full contact with the seal outer diameter so impact energy transfers evenly, lowering the risk of cocked seals or edge damage.

• Aircraft-grade aluminum construction protects mating parts
• Precisely sized driver faces match common hub seal diameters
• Even force distribution reduces seal distortion and leaks
• Use with a rubber mallet for controlled impact (mallet not included)

Which truck models and hub sizes will this fit?

The set is designed for over-the-road Class 7 and Class 8 trucks from major manufacturers. It covers the most common hub outer diameters used on Freightliner, Peterbilt, Kenworth and International vehicles so you won’t need custom adapters for routine jobs.

• Fits hub diameters from 4-13/16" to 6-5/16"
• Compatible with many Freightliner, Peterbilt, Kenworth, International hubs
• Suitable for both trucks and trailers with matching hub sizes
• Designed for on-vehicle use — no drum removal required in most cases

What’s included and how do you use each piece?

The kit contains five drivers sized to common hub seal outer diameters plus a handle extension made for deep-dish brake drums. Select the driver that matches the seal outer edge, attach it to the handle extension, seat the seal squarely, and strike with a rubber mallet until flush.

• Drivers: 4-13/16", 5-11/16", 5-31/32", 6", 6-5/16"
• Handle extension for reach into deep brake assemblies
• Tool faces are machined to ensure concentric seating
• Designed for use with controlled mallet strikes (mallet sold separately)

How does this kit save time during fleet maintenance?

By avoiding trial-and-error adapters and reducing the need for drum disassembly, technicians can complete seal replacements faster and with fewer parts to replace. The ergonomic extension and balanced drivers speed alignment and lower rework caused by damaged seals.

• Cut repair time by enabling on-hub installations
• Fewer damaged seals means fewer follow-up repairs
• One set covers a broad span of common hub sizes
• Durable aluminum construction keeps drivers serviceable longer

If you regularly replace axle hub seals and need a reliable, non-marring, easy-to-use driver set that covers common hub sizes and fits major truck brands, this kit reduces risk and speeds up routine seal work.
