 Application Data

•  Toyota LJ70
•  Toyota KZJ70

 NOTE that these axle shafts have a seal diameter of 33mm, the same as Hilux, FJ40 and FJ60.  Some LJ70 and KZJ70 shafts have a seal diameter of 35mm the same as FJ80.  If this is the case the standard axle seals will not fit.

Having issues lining up all the gaskets to get the spindle bolts installed? Our Super Metal Spindle Stud Kit eliminates that problem by removing the stock bolts and replacing the spindle hardware with studs.

These studs are stronger than stock Toyota replacement spindle bolts providing great strength without breaking the bank. Each stud is constructed from a proprietary alloy made exclusively for Trail Gear.  These studs are manufactured to our strict specifications and are significantly stronger than OEM standard (testing exceeded Class 12.9 standards of 177,000 psi tensile strength). These studs should be your first choice for spindle hardware replacement or upgrade.

Kit Includes:

• 16x Super Metal Spindle Studs
• 16x Nylock Lock Nut

Need an E-brake? Have bad cables, or a disk brake conversion? We have the answer with our simple and affordable Toyota T-case E-Brake Kit. It can be installed in under 1 hour and is fully bolt on. You do have to remove the t-case output flange in order to clearance the dust seal cover.

The E-brake kit reuses your stock e-brake cable up to the frame mounted e-brake arm located in front of your fuel tank. The t-case e-brake is constructed of laser cut and tig welded CNC formed 1/4 plate steel. Includes all parts you will need for installation, comes with instructions.

Fits all 4 cyl. Manual Toyota t-case's. Bracket’s are designed with a skid plate below the caliper and the ends are formed and tig welded to the main plate. The box style mount helps ensure no flexing of the t-case and caliper mount. This helps eliminate wear on the pads as well as possible stress on the t case itself. May not fit with all aftermarket t-case crossmembers.

Please note: 79-83 will require swapping to large 10mm bolt pattern flanges.  Due to many variations in Skid plates, transfer case combination,motor and trans mounts, fuel lines closest to rotor of t case e-brake may need to be relocated to clear. This is very common on 4 runners where the body is lower for rear passenger foot well. Depending on how much t case skid plate lifts the transfer case, trimming and boxing of floorboard may be required.

Instructions:

Installation of the t case e-brake requires you remove the t case output flange and remove the dust cover to fit rotor to back side of flange.

After removing flange and dust cover install rotor to back side of flange. We use the stock drive shaft bolts to position the rotor, the rotor is tapped for 2 patterns, determine the correct pattern for your drive shaft.

Next remove 4 bolts on the back transfer case cover, these are the bottom 2 and 2 above them. There is also a 5th bolt to remove on the far outside edge of the case, use the caliper mount to determine which one if unsure. This bolt will use the included spacer. Install t case flange with rotor, then slide caliper mount and caliper up to the rotor and install new longer bolts, flat washers and lock washer. Install jam nuts to all thread, then install yoke ends to all thread. Install arm to caliper mount, position of the arm will need to be determined by the installer as to which direction the arm will point and which holes to use. You may flip the arm and use the 3 adjustable yoke holes or use the standard single hole to install on the mount. Install 2.5 x 3/8ths bolt, flat washers and locknut. It is not necessary to tighten the lock nut completely, the arm should move freely but not be loose. Install the adjustable yoke ends with all thread and jam nuts. One end will use the spring to hold the pin, the other side will use the cotter pin. The shoulder bolt will fit through the stock e brake cable eye on the end of the e-brake arm. Note: 79-83 style cable will require a loop installed with wire crimp. Final adjustment may be needed and is the responsibility of the final installer.

Anyone who has dual cases with 4.70 gears in their Toyota rock crawler has at one time or another broken an OEM rubber motor mount and heard the awful sound of their fan blades hitting their radiator. We have an answer for that problem, we call it the Bomb Proof Motor Mount Kit. We feel so confident about this product that we back it up with a world famous No Questions Asked Lifetime Warranty.

The base of the motor mount (frame side) is made out of 1/4 inch plate, while the surface plate that the motor sits on is made out of 3/8 inch material and has a class 10.9 bolt that is mechanically locked to the engine mount plate, not just threaded in. The bushings out of a high grade polyurethane for durability and years of dependability. The finish is a clear zinc plating that looks sharp and will last a lifetime. The mount holes are slotted so that the Bomb Proof Motor Mount Kit is easy to install and can be used on 3.5 inch and 3.75 inch applications. You dont even have to measure to figure out what motor you have; the Bomb Proof Motor Mount Kit just works. Note: This product may cause more vibration than the OEM rubber mounts. This is the trade-off we make when going to stronger components.

 Applications:

 1979-1995 Pickup and 4Runner 4 Cylinder 22R, 22RE, 21R, 20R, 18R, 3.0L 3VZE V6, 2.7 3RZFE 4CYL, and 3.4L 5VZFE V6.

The ARB  Air Locker is one of the world’s most highly regarded traction aid. The 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.

Models

RD132 Toyota 8 inch 4cyl, V6 and High Pinion FJ80 Air Locker

The RD132 Superceeds the RD23 in March of 2007.

If you have a 4cyl differential, late model 50.00mm [1.969"] id carrier Bearings must be used. (ARB Part No. 160116)

RD142 Toyota Land Cruiser 9.5" Air Locker Full Floating

Please Note: The RD142 is made for all 50mm carrier bearings. If you are installing an Air Locker into an earlier model Toyota with a 45mm differential carrier bearing inside diameter then you will need to use the higher rated later model 50mm bearings: Timken # 32010X-32010X or ARB # 160116. If your OE carrier bearings have an ID of 50mm, replace them with new bearings of the same type.

Toyota Land Cruiser 9.5" Differentials (12 Bolt Full Floating. What does this mean "Full Float"?  The axle shaft is splined on both ends, the axle shaft does not support the weight of the vehicle, the bearings do- therefore, the axle "Floats" inside the axle housing.)

Please Note, this will not fit FJ80 / LX450 Front as these are 8" high pinion reverse rotation differentials. 

This locker will not work with any of the semi float c-clip rear axles!

How do I tell if I have a full floating or semi floating rear axle?  If the wheel hub is flush with the wheel it is a semi floating rear axle. If it has a hub that sticks out past the wheel then it is a full floating rear axle.

 Manufactured in the U.S. using only high-strength chromoly materials, RCV Performance Ultimate 30 spline CV Axle set simply replaces your weak Toyota axle shafts with a new high-strength design. The factory axles were designed with 30 splines at the differential, and neck down to 27 Spline at the CV creating a common failure point. This axle set upgrades the weak 27 splines at the CV to a 300M 30 spline race eliminating the need to neck down the shaft.

Tests prove Ultimate CV Axles to be twice as strong as OEM shafts, and they're just as tough at a straight angle as they are at extreme angles. Even if you have big tires and big power there are no worries. Ultimate CV Axles are low maintenance and operate with a smoothness you can feel - whether off road or on the street.

Axle set includes right and left inner axle shafts & 2 pregreased CV joints. Black oxide coating is standard, We can accommodate custom length inner shafts as well if needed.

What makes these axles unique among any other axle set is that the inner race is made from 300M. You can tell that the race is 300M by a slight discoloration from the rest of the birfield. These are the only birfields that have this billet 300M race.

Includes:

Inner Axle Shaft -Long

Inner Axle Shaft -Short

2 - 4340 Chromoly and 300M RCV Birfields

2- Inner Hub Gears, 4340 Chromoly

1986 and later Hilux pickup trucks and 4Runner feature larger vented rotors from the factory. Earlier 1979-1985 trucks used solid (non vented) rotors up front along with smaller calipers. If your installing a solid front axle on an 86 and later rig you will want to install a set of these vented rotors onto the axle. With these rotors you will be able use your existing larger IFS calipers. Simply unbolt your existing rotors and replace them with these vented rotors. Slight grinding of the rotors backing plate will be needed. Then simply install the IFS calipers right on to the solid axle using the factory bolts. These rotors can also be used on 85 and older trucks to increase braking effectiveness. Fits 81-85 Solid axles with 8 hole style rotors.

Price is per rotor. You will need 2 to do one axle.
