Differential Breather Kit
Prevents dirt, debris and water from getting in to your axle through the stock axle housing breather. Expands and contracts to accommodate increase or decrease in housing pressure. Kit includes one housing fitting, clamp and bellows (as shown). Easy installation takes just a few minutes. No hoses to route. Fits all Toyota Pickup / 4Runner solid axle housings (front or rear).

Note: This product is not compatible with the rear Rock Assault axle upper 4 link mount.

Ring & Pinion Differential Gears
Are you feeling the lag of those bigger tires or plan on adding some bigger tires? Anything more than a couple of sizes larger and you will need some gearing help. Our supplier has been making top quality Toyota gears for years. They are designed to run quiet and last longer than other aftermarket gear sets. Take your pick of several different ratios for each Toyota axle. Most stock axles run 4.11 gearing with around a 30" tire so we recommend 4.56 gears for 32" tires, 4.88's for 33"-34" tires, and 5.29 for 35" tires and up. We also carry 5.71 Gears but do NOT suggest them for heavy duty off road use.

Differential Setup Kits
These install kits include what you need to make your gear setup a breeze. Kit includes high quality bearings from manufacturers such as Koyo and Timken, crush sleeve, gear marking paint & brush, shims, and pinion seal.

E-Locker Carrier Side Bearing
Have an Electric Locking Differential found in 4Runner's, TRD Tacoma's, FJ Cruisers , FJ80 Landcrusers and Lexus LX450's? Trying to find an affordable bearing kit, but can't find one for the Electric Locking Diff? We now have available the large E-locker Carrier Side bearing to complete the install kit needed to rebuild your differential. You can purchase the master rebuild kit above which includes this bearing, or order the bearing seperate. This is an OEM KOYO Bearing, only one needed per differential.

Solid Pinion Spacer
Solid pinion spacers prevent loosening of the gear setup preload. Originally designed for older Toyota applications, Toyota stopped using them decades ago. Solid spacer and shims replace the crush sleeve. It takes a little longer to set up but you won't have to keep retorque the pinion nut down the road.

ARB Air Locker
The world’s most highly regarded traction aid, an ARB Air Locker is a driver controlled locking differential originally designed to give serious 4 wheelers the traction needed to combat extreme off road terrain. When extra traction is required, the driver activates the Air Locker via a convenient dash mounted switch. Pneumatic pressure supplied by an on board air compressor engages ARB’s patented locking mechanism within the Air Locker, thus preventing the wheels from turning independently. The Air Locker is deactivated by flicking a switch, returning the differential to normal. By far the most coveted locker in the world! Choose from front or rear lockers.

ARB Air Compressors
4x4 air compressors provide truck owners with many advantages regardless of whether you're four wheeling, camping, fishing or hunting.
ARB has a line of models, from vehicle mounted options to a portable air
compressor, each suitable for numerous tasks including specific models available for Air Locker activation.

Few 4x4 accessories offer as many advantages as readily available on-board air. Considered by truck owners around the world to be a staple accessory for off road travel, an ARB 4x4 air compressor provides an immediate source of compressed air anywhere a 12 volt power source is available.

Tires perform best when they're set at a pressure that's appropriate for the terrain. While highway use calls for a relatively high pressure rate, lowering your air pressure will dramatically improve your 4x4's traction in a range of off road environments. Compressed air allows you the freedom to adjust the tire inflation level of your truck to suit the conditions.

An equally beneficial feature of on-board air is the ability to re-inflate tires that have been repaired - it's not unusual to get several punctures in one day when 4WDing in extreme off road conditions. In this environment, the value of owning a 4x4 air compressor is priceless. When coupled with good quality tire repair equipment, an ARB air compressor provides the off road traveler with independence and peace of mind.

ARB 4x4 air compressors are individually leak tested, current draw tested and flow tested under load at the factory before packaging and come with a comprehensive 2 year warranty. And ARB's after-sales service is second to none with many of the compressor components readily available and easily sourced.

CKSA12 - This compact vehicle mounted Air Locker Air Activation System has been specifically designed to provide on-board air for activating ARB Air Locker locking differentials. A smaller unit, it comes with a mounting bracket that allows versatile positioning and is sealed for moisture and dust resistance with quality components used for reliable compressed air and extra long life.

CKMA12 - Permanently mounted, this compressor is installed into your truck and includes a full wiring loom with Air Locker solenoid plug in contacts, mounting hardware with reinforcing bracket and quality compressor isolating switch. This compressor can be used to activate Air Lockers, and can perform other functions such as inflating camping gear with an optional inflation kit sold separately.

Automatic Lockers

For ease of install and people who are on a budget, Powertrax Lockright lockers are hard to beat. Of course, selectable lockers such as ARB air lockers would be much more desirable, the Lockright lockers get the job done for a fraction of the cost. Many differentials have a set of spider gears which allow the outside tire to turn faster than the inside for a smooth turn. These lockers still allow for this at low torque. But when you add torque or are heading strait down the road the locker automatically delivers 100% lockup to keep you moving.

Detroit Locker
These Eaton Detroit Lockers are designed to maximize traction by delivering 100 percent of the torque and power to both drive wheels. Detroit Lockers offer full and positive traction for serious rock crawling. Detroit lockers work like a ratchet wrench, allowing one wheel to spin faster as needed for going around corners but does not allow either wheel to go slower than the drive speed. Totally automatic with no buttons to press. Solid reliability!

Differential Stud Eliminator Kit
When you come home after a trail ride do you see oil leaking from the center of your axle housings? The stock axle housing studs may be pulling loose. No longer do you have to tap and drill the studs out and replace the studs. Our new stud eliminator kit replaced the studs with allen head bolts that won't pull through like the stock studs. Kit includes 10 high strength studs, nuts, washers and a tube of Ultra Gray Silicon gasket material.

Full Spool
Spools are a simple and inexpensive way to lock up your differential. No moving parts. Simply install and hit the trails. Solid one-piece construction. Not recommended for on-road use.

Creeper Joint™ Drive Shaft U-Joints
The Heavy Duty Creeper JointTM has been tested to 4,700 ft-lbs of torque in Trail- Gear’s very own axle testing machine. These U-joints fit most 1979-1995 4wd applications. Includes four install clips and and Zerk grease fitting (not shown in photo). These u-joints have been trail tested and have been proven to provide excellent strength at a reasonable price. Just as a comparison, the stock joints fail at 3,700 ft-lbs of torque. We find that keeping a spare is at least a good backup when out on the trail.

Stock Replacement Drive Shaft U-Joints
OEM Replacement U-Joint. These have been tested to 3700 ft-lbs of torque before failure...Exact same as Toyota U-Joints. U-Joints fit most 1979-1995 4wd applications. Includes four install clips and and Zerk grease fitting (not shown in photo). Priced way lower than factory joints and work just the same!

Long Spline Drive Shaft Kit - 10 inch
When installing a lift and crossover steering you need a long spline drive shaft, especially in the front. A flexy front suspension system requires more slip spline then the stock shaft is able to provide. The result with a stock drive spline is the drive shaft comes apart on the trail. This long spline kit is designed to replace the stock slip section.

To install this kit the stock slip section and tubing is cut off and then section along with new tubing is welded in place. Tubing is not included but will be available separately at a later time.

With other kits on the market why purchase ours? All-Spline technology allows the spline to taper in to a shaft that is .180" larger than stock. These drive shaft kits are specially heat treated and hardened to prevent bending. Best of all it has 10" of spline travel, that's 2" longer then other similar kits on the market. That gives you the flexibility to make changes to your rig without the need to redo your shafts.

Kit comes with U-joint installed and tack welded in place to ensure it does not come out on the trail.

Drive Shaft Bolts
Replacement drive shaft bolts, nuts and washers. Bolts include factory thread lock adhesive applied to threads.

Differential Housings
Building your own 3rd members? Our 3rd member housings include caps, cap bolts, adjusting wheels, lock tabs, and lock tab bolts. Housings are all new, no core return!

High Pinion Conversion Kit
Running a High Pinion differential compared to the past is now affordable. We have put together a conversion kit that will allow you to use your current V 6 locker with our complete High Pinion conversion kits.

The kit will include everything that you will need to upgrade to a High Pinion differential:

• High pinion differential housing
• High pinion oil slinger
• Ring & pinion setup kit

V6 Differential Freeze Plug
Later style V6 3rd member housings have a hole on the top for the anti-lock brake speed sensor. If your installing this 3rd member into an older truck without anti-lock brakes you will need to plug the hole. These freeze plugs do the trick and are easy to install with a small socket and hammer.

Triple Drilled Flanges and Dust Shields
Has all the common 1984-1995 patterns in one, universal output flange. Includes 4cyl CV and Non CV patterns as well as V6 CV pattern. Makes sourcing and reversing drive lines much easier. Fits gear driven transfer cases and 8" differentials.
Make sure and tell us if you are installing on a differential or transfer case.
