Fitment & Measurements
This kit is intended for compatible 3,500 lb trailer axles equipped with the appropriate spindle dimensions and four-bolt brake mounting flanges. It may be used with qualifying leaf-spring or torsion axle configurations.
Brake Mounting Flange
The original listing specifies a 2-7/8" center-to-center mounting-hole measurement on the four-bolt brake backing plate pattern. Confirm the flange pattern against the actual brake assembly.
The axle must have a correctly sized and positioned four-bolt brake mounting flange. If it does not, the required flange must be professionally installed before the brakes can be mounted.
Spindle & Bearing Identification
Compare your spindle bearing journals and seal surface with the supplied L68149, L44649, and 10-19 components.
Many 3,500 lb trailer axles use an approximately 2-3/8" outside-diameter axle tube. Smaller and larger axle families use different spindle and brake configurations. Tube diameter is a useful identification clue, but it does not establish fitment by itself.
5 on 4.5" Wheel Bolt Pattern
Verify the wheel bolt pattern before ordering. This kit includes 5 on 4.5" hubs.
Four-Bolt Brake Mounting Flange
Check for the welded four-bolt mounting flange behind each spindle. Installation or correction of brake mounting flanges requires appropriate professional welding and alignment.
Complete Kit vs. Basic Kit
Complete Brake Kit: Intended for a compatible trailer receiving electric brakes for the first time, including trailer-side wiring and breakaway equipment.
Basic Brake Kit: Typically intended for replacing existing brake components or adding brakes to another axle where the appropriate electrical and breakaway systems are already installed.

R&P Knowledge Hub
How Never Adjust brakes work: Dexter Never Adjust electric drum brakes use a self-adjusting mechanism to compensate for normal brake shoe wear. The braking system still requires correct initial installation, inspection, and periodic maintenance. How the system connects: The tow vehicle's brake controller sends an electrical signal through the 7-way connection to the trailer's brake magnets. The resulting brake application slows the trailer through the hub and drum assemblies. Why the breakaway equipment matters: A properly installed and charged breakaway system activates the trailer brakes if the trailer separates from the tow vehicle, subject to the equipment's intended operating conditions. Before installation: Confirm the axle rating, spindle dimensions, brake flange configuration, hub bolt pattern, wheel compatibility, wiring, and brake-controller requirements. Follow Dexter's current installation and maintenance instructions. |
FITMENT CHECK
Not every five-lug trailer uses a 3,500 lb spindle or the same brake mounting configuration. Verify your spindle bearings, grease seal, flange dimensions, and 5 on 4.5" bolt pattern before purchasing. This kit does not include installation or modification of axle mounting flanges.
