Product Description

Overslung/Underslung Conversion Kit

The Over/Under Conversion Kit is designed for trailers with 2-3/8” axle tubes. Its primary function is to convert the mounting position of the trailer axle between overslung (mounted above the springs) and underslung (mounted below the springs). This conversion allows for adjustments in ride height, which can be useful for increasing ground clearance or lowering the trailer for easier loading.

Key Features:

Components Included:

• Spring seat weldments

• U-bolts

• Hex nuts

• Coupling nuts

• Tie plates

Compatibility: Primarily for 2-3/8” diameter axle tubes used in sprung trailer suspensions.

The kit is widely used in trailer systems that need modifications for height adjustments without major structural changes. It’s especially useful for those looking to improve vehicle stability or ensure proper brake function by reconfiguring the axle and spring positions.

Application Benefits:

• Adjusting the ride height of the trailer to fit specific towing requirements.

• Allows better clearance for various terrains when the axle is moved to an underslung or overslung position.

This kit can be useful for trailers that need precise height adjustments while keeping their original brake system and suspension intact

for 2-3/8" Dia. Tube

This axle conversion kit fit my trailer just right. All components & hardware are all well-made heavy duty solid pieces. Has been on my trailer for three months now and so far no rust and all still holding strong and secure. Very happy with the quality of this kit!

The AGILLE K7138400 Axle Conversion Kit is a great DIY or professional trailer part accessory. The axle kit, which includes the Spring seats, U-bolts, Tie Plates and heavy-duty bolts is made well with high quality materials. All of steel alloy pieces are extremely durable, rust/corrosive resistant, and long-lasting. Designed to increase the height of a trailer’s axle, installation of the kit requires having the proper tools and an appropriate level of mechanical skill. In short, I like this product because it has all of the components needed to complete the task.

This axle conversion kit is going to be used for a utility trailer. It was examined and it looks like it's good quality and will fit, but we're waiting for spring. It will be used to upgrade the axle size to a heavier duty one. Happy with order. We'll update if our review changes after installation.

After installing and torquing to spec (60 lb) I noticed the plate and u-bolts had all deformed.I removed and re-used the old ones, as they appeared to be in much better condition.The axle perch and bolts/coupling nuts spacers are great, but the u-bolt hardware is garbage. I tossed it in the trash with an hour.
