ARB Differential Breather Kit

ARB Differential Breather Kit.

It’s not news that oil and water don’t mix, but if it happens inside a driveline component and you are unaware, the results will eventually be catastrophic. The factory differential breathers on late-model Rams are raised slightly, to near the top of the tires, which is good enough for most folks. Hopefully that would be plenty for me too, as I’m not a fan of playing in deep water or soupy mud. However, it has happened before, including an unfortunate loss of forward progress that lasted hours. Being an ounce-of-prevention guy, I chose to be proactive regarding keeping the H2O out of my gearing lubricants.

For decades I have extended the breathers for driveline components using small, inexpensive air or fuel filters, but a few years ago ARB introduced a most tidy aftermarket solution that I’ve used since. Employing the same filter as their 12-volt air compressors, ARB makes a neat aluminum manifold into which their filter and extended vent lines attach. Vent tubing and fittings are also supplied, and the kit retails for $72.

For the 2017 Ram/Cummins 2500 Pack Mule with Hallmark flatbed camper, I mounted the ARB manifold at the top left of the engine compartment, similar to my 2014 Ram, but I drilled a new hole this time. Using the OE rubber vent hose as my start, the rear axle breather line was extended using ARB’s plastic vent tubing, first inside the Hillsboro flatbed frame, then along the truck frame under the cab and up into the engine compartment. The front differential vent was extended the short distance from near the left front shock, and the transfer-case breather was raised from atop that gearbox into the engine compartment. A trained eye might notice the ARB Differential Breather Kit as aftermarket, but it’s very tidy and clean.

Low, factory vent hoses/caps can get clogged with goop, snow, or ice, causing housing pressure that can lead to leaks. Mounted in this spot, the filter just clears the closed hood.

Toyo Open Country C/T 10,000 Mile Review

Toyo C/T 10,000 mile report

When the Toyo Open Country C/T was initially introduced it was only available in Canada. A few years ago, when that changed, it moved to the top of my must try list. Commercial traction or hybrid designs are my favorite type of tread, and the C/T might be the best, slowest-wearing design I’ve used on any truck in several years; maybe ever.

The Toyo C/T has the severe snow, mountain snowflake rating.

Mount, balance, and tracking

Because the Open Country C/T is an on/off-road commercial-grade tire, there are fewer sizes offered than other Toyos like the Toyo A/ T II. However, there are still six 16-inch, seven 17-inch, five 18-inch, and seven 20-inch sizes available.

For this evaluation I mounted 35×12.50R17 on forged aluminum OEM Ram Power Wagon wheels. They required very little weight to balance, typical for Toyos, and ran smoothly down the highway at all speeds.

104-pounds on OEM 17″ forged aluminum Power Wagon wheel, needing only 1.25 ounces for a static balance.

Initially mounted my 2014 crew cab, which has an SPC offset right ball joint to counteract treads that pull to the right, the C/T would drift just slightly to the left after a few seconds with no hands on the steering wheel, depending on the road crown. (To be perfectly clear, this is because of the offset ball joint and caster settings, not a characteristic of the tires, the C/T does not appear to pull right or left, they are neutral.) On the 2017 Ram 2500 regular cab with Hallmark flatbed camper, the C/T track perfectly straight for several seconds on flat roadways. They were a great match for the outfit, and where I decided to keep them for this evaluation.

Almost all the miles logged have been with this 2017 Ram 2500 Hallmark flatbed camper outfit.

General traction and performance

The C/Ts saw a little of most terrains, including snow, packed dirt, gravel, rock and plenty of pavement. Deep off-highway mud, snow, and deep sand were not experienced; a 10,000-pound camper outfit is less happy on these surfaces, so I only drive on them when necessary. However, with the good void-ratio and siping this tread offers, I’m confident the C/T would perform as well or better than similar commercial-traction designs.

Many modern tires perform well in moderate on-highway or off-highway snow, and this was true with the C/T. However, the mountain snowflake severe winter rating provides extra assurance in wet conditions, and I would pick the C/T over many hybrid or all-terrain designs for winter service. Obviously they are unlikely to perform as well as a dedicated winter tire, but those designs are less versatile on heavily-loaded trucks and rarely offered in larger sizes.

The Open Country C/T is quiet for the void it offers, and no louder than the Toyo R/T or A/T II Xtreme with which I am familiar in similar sizes. I’ve recommended the C/T to many of my readers, including a professional photographer and adventurer who lives in Jackson, Wyoming. He has been impressed with their snow capabilities. Another guy lives full-time in his heavy truck camper and uses them.

Wear close-ups 

You can see a small amount the feathering on the outer lug sipes. For nearly 6,000 miles without a rotation, this minor visible wear was impressive and not concerning. Appropriate rotations will true-up the tread.

Slow and even wear, 6,000 miles since the last rotation, most of it on highways.

Phenomenal Longevity

As my video assessment and testimonial enthusiastically shares, I am most impressed with the slow rate-of-wear on these Toyo Open Country C/T, better than any other tread in years, maybe ever.

17/32″ of tread depth remaining after 10,000 miles!

The 4,400 miles per 1/32 of depth is exceptional, particularly for such a heavily-loaded, diesel, truck camper outfit. Was the slow treadwear due to a higher than typical percentage of highway miles? Possibly, although my outfit is not a daily driver and routinely sees many more long-distance travel miles than city driving. Double the mileage of most tires I’ve run on diesel trucks, and still 50-percent more than other standouts is nothing short of phenomenal!

Absolutely love these Toyo C/T tires and would like to try them in a 295/65R20 size.

The C/Ts were removed from service only to begin another review, but I’d like to run them again soon, preferably in an 18-inch or 20-inch size with a higher load-index that’s better suited to my heavy camper. The 35×12.50R17 was chosen because I wanted a 35-inch size, and I already had the wheels. At the time I was adamantly against 20-inch tires because the shorter sidewalls offer less flex off-pavement. Though shorter, less flexible sidewalls can be a huge a positive for overall camper stability and handling. My opinion has softened, as long as the tire is tall enough that there’s adequate sidewall.

Timbren DRTT3500E Spring Kit

On Dec. 23, 2019, I installed the firmer Timbren Industries single-convoluted springs, replacing the DR2500D double spring I ran for six months. I needed to reuse the bracket from the double-spring kit because there was a packaging mistake with my order.

However the springs, mounting brackets, and included Timbren spacers are interchangeable, just the spring mounts are different heights for this application. Received the correct and taller DRTT3500E mounting bracket and did the R&R. Without a 1-inch spacer the new setup is 3/4-inch taller overall.

Slides: 1) Shows the new set up on the left and what I’ve been running for three weeks on the right. 2) What I was running installed 3) What I’m running now, which is the traditional DRTT3500E spring mount/kit, without the optional spacer.

Air Lift 1000 auxiliary air springs

My flatbed camper outfit works well, but I’m always tinkering, fine-tuning, and looking for small improvements. I’m still using and loving the TufTruck and Timbren springs, just also want to inflate these air springs again which have been sitting dormant for months.

Essentially the same Air Lift product has been on my 2006 4Runner for over a decade (they’ve been flawless, after another brand failed twice). Also on my 2014 Ram 2500 since new, including up to the Canadian Arctic Ocean a few years ago. That’s a good record, so I’ll give this one failure a pass.
