With 30 spline birfields, six stud knuckles, and chromo hub gears or drive flanges, the next weak link in your front axle is your hub studs. When they fail you will be left without four wheel drive, and often times the hub will be unrepairable. Trail-Gear, in partnership with ARP, have designed the most durable hub stud on the market. These hub studs are made from the strongest material ARP can manufacture for this type of fastener. ARP 2000 material has a tensile strength of 220,000 PSI and the ARP 2000 hub stud is cadmium plated to ensure that it is protected from rust and corrosion for many rough years to come. On the top of the stud we machined a 6mm hex head so that installation and maintenance is easy and no special tools are required. ARP 2000 hub studs are sold in kits of six with all the necessary hardware included.

Kit Includes:

•  (6) ARP 2000 Hub Studs

•  (6) Conical Washers

•  (6) Lock Washers

•  (6) Nuts

THESE ARE PRICED PER SIDE SO A QUANTITY OF 2 ARE NEEDED FOR ONE VEHICLE.

In many cases, stock wheel bearing nuts and star washers can be used several times. However, with the increased maintenance required of an off road vehicle, these will need to be replaced. Trail-Gear now offers a Chromo Spindle Nut Kit that allows you to more easily service your axle and decreases your long term service costs. The Locking Nut and Washer have been CNC machined from 4130 Chromoly. The Nut has also been heat treated to Grade 8 standards. Kit comes with the hardware necessary for one axle.

Advantages over stock:

• Stronger than stock. Made out of 4130 Chromoly.
• Extends the life of your wheel bearings due to loose spindle nut and OEM lock washer.
• Ease of installation.

This kit includes:

• Thrust Washer (qty 2)
• Spindle Locking Nut (qty2)
• Spindle Locking Washer (qty 2)
• Washer, M3 locking (qty 4)
• M3-.05 Socket Head Cap Screw (qty 4)

NOTE: 1 KIT SERVICES 1 FULL AXLE

When Trail Gear tested the strength of 6 Stud knuckles, they found that running 6 OEM Studs on the 6 Stud knuckles was stronger than running 4 ARP Magnum Studs on a stock 4 stud knuckle.  So, with this information Trail-Gear looked at ways to make it stonger than even running OEM and not the cost of ARP studs. Now, Stronger and longer than stock Toyota replacement knuckle studs and more affordable than our Magnum Studs these studs will provide great strength without breaking the bank. Each stud is constructed from a proprietary metal made exclusively for Trail Gear.  These studs are manufactured to Trail-Gear's strict specifications and are significantly stronger than OEM standard (testing exceeded Class 12.9 standards). Trail Gear super metal knuckle studs are .250” (1/4”) longer than stock to accommodate all aftermarket steering arms. Like our Magnum Studs, TG super metal studs feature an integrated 8mm hex head for easy removal. These studs should be your first choice for knuckle hardware when repairing or upgrading your high-steer system.

We recommend using Locktight on the lower threads when installing knuckle studs. Studs should be tightened to 40 ft-lbs in the knuckles. Stud nuts should be tightened to 75 - 80 ft-lbs.

Fits 1979-1985 Toyota front solid axle knuckle.

NOTE: This is enough hardware to complete one six shooter knuckle. Purchase 2 kits for both knuckles.

Kit consist of the following:

• Knuckle cone washers (QTY: 6)
• Knuckle wave washers (QTY: 10)
• Knuckle nuts (QTY: 10)
• TG Super Metal knuckle studs (QTY: 10)

1990-1997 Toyota Land Cruiser | Lexus LX450 Trail Safe FJ80 Knuckle Ball Wiper Seals by Trail Gear 

Trail-Safe™ FJ80 Knuckle Ball Wiper Seal Kit

The Trail-Safe™ FJ80 Knuckle Ball Wiper Seal is a double sided seal that keeps grease in and dirt out, all while eliminating the use of the OEM felt and rubber. Since it is made from seal-grade polyurethane, not UHMW, the seal is pliable enough to stretch over the knuckle ball during installation. This eliminates the need to cut the seal for installation which allows water to enter the knuckle ball and for grease to escape.

Trail-Safe™ FJ80 Knuckle Ball Wiper Seals are without a doubt the best in the industry. No other design is comparable in performance and quality.

Note:. Trail-Safe™ FJ80 Knuckle Ball Wiper Seals are sold in pairs and one kit will complete one front axle

Specifications:

• Double sided seal
• Eliminates the use of the OEM felt and rubber
• Made from seal-grade polyurethane, not UHMW

Longfield FJ80 Gun Drilled 30-Spline 4340 Chromoly Super Set

The Longfield™ FJ80 Gun Drilled 30-Spline Birfields are made out of 100% chromoly and are precision polished to remove any imperfections that may cause stress risers. The internals of the birfield are also made from 4340 chromoly and are dual heat treated for superior strength. The birfield has a M8 grease zerk at the end of the stub shaft and is gun drilled through the center of the birfield to allow for grease to pass through the zerk fitting and into the internals. This will save you precious time by eliminating the need to disassemble your axle just to service your birfields.

The FJ80 Gun Drilled 30-Spline Birfields also have a shallow relief near the splines on the stub shaft known as a Machined Spline Saver. The Machined Spline Saver eliminates stress concentrations caused by grooving from the tool that makes the splines on the stub shaft. The stress concentration from the spline groove is a common failure point on birfield stub shafts. The stub shaft of the Birfield has dual snap ring grooves to accommodate FJ80s with short and long drive flanges.

The axle shafts are also made out of 4340 chromoly steel.

Included in this kit is a set of new FJ80 ABS Tone Rings. This will allow you to install the Longfield™ FJ80 Gun Drilled 30-Spline Super Set on both ABS and Non-ABS FJ80 applications. No other kit on the market can compare.

Note: Included is the FJ80 Extended Dust Caps for 1990-1993 models that use short drive flanges.
