A 14K trailer axle kit is typically a tandem setup built around two 7,000-pound axles, but the right choice depends on your trailer’s measurements, suspension style, brakes, and included components. The Rockwell American kits below suit buyers seeking complete running gear with tires; the drop-axle kit is for a different axle profile, while the rebuild kit replaces suspension wear parts rather than axles.
| Product | Best For | Key Fitment Detail |
|---|---|---|
| Rockwell American 95/80 kit | Complete kit with tires | 95-inch hub face, 80-inch spring center |
| TK Drop Axle kit | Drop-axle setup | 89/00-inch configuration |
| Tandem suspension rebuild kit | Replacing suspension wear parts | 2-inch shackle straps |
| Rockwell American 85/70 kit | Narrower trailer fitment | 85-inch hub face, 70-inch spring center |
| TK Original Series kit | Mixed idler and brake axles | 95-inch hub face, 80-inch spring center |
Rockwell American 95/80 Complete Tandem Kit
This is a complete tandem running-gear option for a trailer configured for two 7,000-pound axles. The listed fitment is a 95-inch hub face, 80-inch spring center, and 8-on-6.5-inch bolt pattern. It is described for 82-inch-wide trailer frames.
The kit includes two electric-brake axles, double-eye leaf springs, U-bolt kits, tandem hangers, equalizers, shackles, and ST235/80R16 radial tires mounted on 8-lug wheels. Its 12-by-2-inch electric brakes and Posi-Lube spindles are additional practical features.
Best for: Buyers replacing most of a tandem trailer’s running gear at once who need the listed 95/80 measurements and included tires. Check first: The hub face, spring center, frame width, and bolt pattern must match your trailer. This is not the right choice if your trailer needs different axle spacing or suspension measurements.
TK 14K Drop-Axle Tandem Kit
This kit is built around two 7,000-pound electric drum-brake axles and is identified as a 14K-capacity drop-axle series. The listed configuration is 89/00 with loose spring seats and an 8-on-6.5-inch bolt pattern. Included parts are four 3,500-pound, 26⅝-inch, five-leaf slipper springs, two U-bolt kits, and a slipper tandem hanger kit.
Best for: Trailer owners who specifically need a drop-axle configuration with slipper-spring suspension. Its high-strength steel axle tubes and packaged suspension components make it a running-gear option rather than a wear-parts-only kit.
Check first: The supplied information says the axles are not ABS compatible. Confirm the 89/00 configuration, spring-seat arrangement, and axle dimensions with your trailer before ordering; do not assume it matches a standard straight axle.
Tandem Axle Suspension Rebuild Kit
This product is different from a complete 14K axle kit: it replaces suspension wear parts and does not list axles, brakes, tires, or wheels. The kit contains 14 hardened 9/16-by-3-inch shackle bolts, 14 locking nuts, 14 nylon spring bushings, and eight 2-inch-on-center spring shackle straps.
Best for: Owners rebuilding a standard tandem suspension while retaining their existing axles and other running gear. The listing identifies the kit for tandem trailer suspension from 4,000-pound through 14,000-pound gross vehicle weight.
Check first: The 2-inch shackle-strap spacing and bolt dimensions need to match the installed suspension. Avoid this option if you need new axles or a complete axle-and-brake assembly.
Rockwell American 85/70 Tandem Kit
This tandem kit has two 7,000-pound electric-brake axles, for a stated 14,000-pound total axle capacity. Its specifications include an 85-inch hub face, 70-inch spring center, 3-inch axle tube, and 8-on-6.5-inch bolt pattern. The listing says it fits most 72-inch-wide trailer frames.
The running-gear package includes slipper springs, U-bolts, hangers, and ST235/80R16 radial tires mounted on 8-lug wheels. Rockwell American’s Posi-Lube system uses grease zerks to lubricate inner and outer bearings without removing the hub.
Best for: Buyers whose trailer needs the narrower 85/70 measurements and a complete setup with tires. Check first: The 72-inch frame fitment is described as applying to most trailers, not every trailer. Verify the exact dimensions and slipper-spring requirements before selecting it.
TK 95/80 Original Series Kit
This 14K-capacity kit has a 95-inch hub face and 80-inch spring center. Unlike a package with two brake axles, it includes one 7,000-pound idler axle and one 7,000-pound electric drum-brake axle, both listed with half-inch studs.
Suspension components include four 3,500-pound, six-leaf double-eye springs, two U-bolt kits, and a double-eye tandem hanger kit. The package also includes four 16-inch ST235/80R16 10-ply radial tire-and-wheel assemblies with a silver/gray finish.
Best for: Buyers who want a 95/80 setup and specifically prefer one idler axle paired with one electric-brake axle. Check first: This is not equivalent to a kit with electric brakes on both axles. Confirm that the mixed axle arrangement meets your trailer’s braking requirements.
Buying Guide: How To Choose A 14K Trailer Axle Kit
Which measurements should you verify?
Start with hub face and spring center measurements. Hub face is the distance between the wheel-mounting surfaces; spring center is the distance between the spring seats or centers specified for the kit. Also compare axle tube size, trailer frame width, bolt pattern, and spring style. A capacity match alone does not establish fitment.
Do you need a complete kit or a rebuild kit?
A complete running-gear kit may include axles, brakes, suspension hardware, and sometimes tires and wheels. A suspension rebuild kit replaces selected wear parts, such as bushings, bolts, and shackle straps. Check the parts list so you do not mistake a repair kit for a full axle replacement.
Should both axles have electric brakes?
Compare the kit’s brake configuration with your trailer’s requirements. Some packages list electric brakes on both axles; the TK Original Series kit listed here pairs one brake axle with one idler axle. The product descriptions do not establish suitability for every trailer, so verify requirements before purchase or installation.
When does suspension style matter?
Double-eye and slipper springs use different suspension arrangements. Drop axles also have a distinct profile from standard straight axles. Match the kit to the existing trailer design or to a planned conversion, and confirm hanger and spring-seat placement before ordering.
What should you compare in tire-and-wheel packages?
Check the listed tire size, wheel bolt pattern, and included quantity. Several complete kits include ST235/80R16 tires on 8-lug wheels, but the TK drop-axle kit’s listed contents do not include tires. Do not assume wheels or tires are included unless the product description says so.
Frequently Asked Questions
Does a 14K trailer axle kit always include two braked axles?
No. Many kits use two 7,000-pound axles, but brake configurations differ. Check whether brakes are listed on one axle or both.
Can I choose by capacity alone?
No. Match hub face, spring center, frame width, bolt pattern, axle profile, and suspension type as well as capacity.
Does the suspension rebuild kit include axles?
No. Its listed contents are shackle bolts, locking nuts, nylon bushings, and shackle straps.
Are tires included with every kit?
No. Tire-and-wheel assemblies are listed for some kits but not all. Review each package’s included-parts list.
