8K Trailer Axle Kits for Heavy-Duty Trailer Builds
Shop 8K trailer axle kits built for heavy-duty tandem and triple axle trailer setups. This collection includes 16K tandem axle kits, 24K triple axle kits, Axle Series kits, Original Series kits, and complete trailer parts kits for bumper pull and gooseneck trailers.
These kits are designed for builders and repair shops that need more than a single replacement axle. Choose from TK and TK Hybrid 8,000 lb axle kit options with 9/16" studs, electric brake configurations, and kit packages built for demanding hauling applications.
Choosing the Right 8K Trailer Axle Kit
Select a tandem kit when your trailer needs a combined 16K axle capacity, or choose a triple axle kit for a 24K setup. If you are replacing only the axle itself or comparing other capacities, browse our full trailer axles collection for 2K through 16K options.
For complete trailer builds, compare Axle Series kits against Original Series and Complete Original Series kits. Axle Series kits focus on axle and suspension essentials, while complete kits are better suited when you need a fuller parts package for a bumper pull or gooseneck trailer.
