Part Number: D099-160-32 2-5/16" Ball 16,500 lb Capacity
Overview
This Dexter surge brake actuator coupler is a heavy-duty hydraulic braking solution for trailer applications using disc brakes. Built in the DX16.5 platform with a weld-on drop configuration, it gives buyers a verified 16,500 lb coupler capacity, 2-5/16" ball fit, and primed finish for applications where the trailer tongue setup, mounting style, and brake configuration match.
R&P Service Insight
On heavier hydraulic brake trailers, actuator selection is not just about coupler size. You need the correct brake type, tongue configuration, and capacity so the actuator telescopes and applies pressure the way the system was designed to work.
- Brake Match: This model is specified for disc brake actuator applications, not a generic drum/disc crossover listing.
- Tongue Setup: Weld-on drop configuration matters on trailers where coupler height and tongue geometry must stay consistent.
- Capacity Check: Make sure trailer GTW, tongue weight, and actual tow setup do not exceed the actuator’s rated limits.
R&P Knowledge Hub
Compatibility: Designed for trailer applications using a hydraulic surge actuator setup for disc brakes with a 2-5/16" ball connection and weld-on tongue installation.
Vehicle / System Fit: Heavy-duty trailer brake systems using a surge brake actuator mounted to the trailer tongue.
Installation Notes: Verify brake type, tongue design, weld-on drop configuration, hitch ball size, trailer weight, and tongue weight before ordering or installing.
Performance Insight: Surge actuators synchronize trailer braking through telescoping actuator movement that applies hydraulic pressure during deceleration, making correct fit and configuration critical to brake response.
Brand & Fitment Note
Selling Brand: Dexter
Application Reference: Any OEM or platform names in this listing describe compatibility, fitment target, or application style only where supported by verified dimensions, mounting points, and configuration details.
What This Means: This listing is for a Dexter surge brake actuator coupler, not a guaranteed OEM-branded trailer assembly unless specifically stated and verified.
Before Ordering: Verify measurements, mounting style, tongue layout, ball size, brake system type, axle count, tongue weight, and included components before installation.
R&P Repair Insight
Customers often match only the ball size and overall capacity, but the wrong actuator style can still create fitment or braking problems. Weld-on drop style, brake type, and trailer tongue setup should all be confirmed before purchase.
- Brake Type Check: Confirm your trailer uses a disc brake actuator setup.
- Mounting Check: Confirm your existing coupler is a weld-on drop style and that replacement geometry matches your trailer tongue layout.
- Rating Check: Confirm gross trailer weight and tongue weight stay within the actuator’s 16,500 lb and 1,650 lb ratings.
