Upgrading Axle on 2026 Keystone Cougar 260MLE  

Updated 11/19/2025 | Published 10/25/2025

Question:

Im looking to replace the axles on my 2026 Cougar 260 MLE. One is bent, still under warranty but I want something heavier duty - perhaps 7,000 lbs with electric brakes, self adjusting. Dexter: 7608250 S/N: 132398507010 D52 Capacity: 5100 LBS HF =86.50 SC =68.50 Gary 920-392-2582

Hi Gary; the highest capacity we have that matches your current axle length is 6,000 lbs. The Dexter Trailer Axle Beam with E-Z Lube Spindles - 86-1/2" Long # 8327826 will work as a replacement. Since the spring center measurement is slightly different you will also need to cut off the spring seats and weld on # TRSS300 to match your 68-1/2" measurement. If you want brakes as well you can use the # 23-458-459.

Hey Gary, how did the swap to the 6,000‑lb Dexter axle and brakes work out on your Cougar? Your update could make it easier for others looking to upgrade from a 5,100‑lb setup.

@RobinH 5100lb to 6000lb axles I ordered two from Dexter. They built them using specifications from the original part number on the axle, direct replacement, no modifications need. They increased the tube thickness from 0.188" (just over 3/16") to 0.300" (just under 5/16"). I also had the brakes upgraded to "self adjusting". Haven't received them yet, takes about 2 weeks. I should get them on November 22nd. Gary
