RAM adjustable channel mount trailer coupler for 2-5/16" ball applications where the trailer channel bracket, mounting configuration, and coupler requirements match. This listing is for the coupler only. Adjustable channel bracket and mounting hardware are not included.

SKU: CTA-400-Z 2-5/16" Ball Coupler Only

Overview

The CTA-400-Z is a RAM adjustable channel mount trailer coupler designed for 2-5/16" trailer ball applications. This coupler is intended for adjustable channel-style trailer setups where the coupler body, ball size, mounting holes, and trailer channel bracket match. This is the coupler-only listing; mounting hardware and the adjustable channel bracket are not included.

R&P Service Insight

Adjustable channel couplers are commonly replaced when the latch, ball pocket, mounting holes, or coupler body show wear or damage. Before ordering, compare your existing coupler and bracket setup carefully so the replacement matches your trailer.

Coupler Only: Includes one RAM CTA-400-Z adjustable channel mount trailer coupler.
Ball Size: Built for 2-5/16" trailer ball applications where fitment matches.
Not Included: Adjustable channel bracket and mounting hardware are not included.

R&P Knowledge Hub

Compatibility: Intended for adjustable channel mount trailer coupler applications using the RAM CTA-400-Z coupler where the trailer bracket and mounting configuration match.

Vehicle / System Fit: Used on trailers with adjustable channel-style coupler mounting where a 2-5/16" ball coupler is required.

Installation Notes: Confirm your adjustable channel bracket, hole spacing, mounting width, ball size, coupler rating requirement, and hardware needs before installation.

Performance Insight: A correct coupler fit depends on more than ball size. The channel bracket, mounting-hole alignment, latch condition, and proper hardware selection all need to be verified before towing.

Brand & Fitment Note

Selling Brand: RAM

Application Reference: CTA-400-Z describes the included RAM coupler component. Fitment depends on your trailer channel bracket, ball size, mounting holes, and installation requirements.

What This Means: This listing is for one RAM CTA-400-Z adjustable channel mount trailer coupler only. It is not a hardware kit and it does not include the adjustable channel bracket.

Before Ordering: Verify bracket compatibility, coupler rating requirements, 2-5/16" ball size, mounting hole fit, and required hardware before installation.

R&P Repair Insight

When replacing an adjustable coupler, inspect the coupler and the channel bracket together. Worn holes, loose mounting points, damaged latch parts, or a mismatched bracket can affect the installation even when the replacement coupler is the correct ball size.

Bracket Check: Confirm your trailer has the correct adjustable channel bracket for the CTA-400-Z coupler.
Hardware Check: Mounting hardware is not included; verify the correct hardware requirements for your trailer and coupler installation.
Final Check: Torque, latch engagement, ball fit, and safety setup should be inspected before towing.
