Overview
The Trail Gear 140063-1-KIT is a triple drilled output flange with a differential dust cover, and it fits the 1984–1995 Toyota 4Runner and 1979–1995 Toyota Pickup. It is a front position part that carries all the common 1984–1995 driveshaft bolt patterns in one flange.
The flange is a universal output flange. It includes the 4-cylinder CV and non-CV patterns as well as the V6 CV pattern, which makes swapping and reversing drive lines simpler. It fits gear driven transfer cases and 8in. differentials.
Because one flange covers three patterns, a builder swapping driveshafts between different Toyota trucks can keep a single flange design on the shelf instead of matching a separate yoke to each driveline.
The flange is sold as a kit, with the dust cover included in the product name, so a builder does not need to find a separate cover for the differential. The 4Runner and Pickup fitment list gives the full range of years that Trail Gear matches to this flange.
Key features
- Triple drilled output flange with differential dust cover
- Carries the common 1984 to 1995 patterns in one flange
- Includes 4-cylinder CV and non-CV patterns
- Includes the V6 CV pattern
- Fits gear driven transfer cases
- Fits 8in. differentials
Driveline swap planning
A driveshaft swap usually involves more than the flange. Measure the transfer case output and the differential pinion before ordering, then confirm the yoke, U-joint and driveshaft length match the new setup. Mixing a 4-cylinder pattern with a V6 transfer case can leave the bolts unable to line up, so check the pattern on both ends. Keep the dust cover seated cleanly so grit stays out of the differential seal.
Torque each flange bolt to the value given for your vehicle and recheck after the first few drives. Driveshaft vibration often traces back to a loose flange or worn U-joint, so inspect both when the truck starts to shake. Keep a spare set of flange bolts and a torque wrench in the tool box when running off-road.

Vehicle fitment
Its fitment covers these Toyota models, with the trims shown:
- 1984–1995 Toyota 4Runner (DLX, SR5)

The flange covers the 1984–1995 4Runner and the 1979–1995 Pickup only. Chain driven transfer cases are not covered. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The flange fits gear driven transfer cases and 8in. differentials, so check which transfer case and differential your Toyota has before ordering. Trail Gear presents the flange as a way to make reversing drive lines easier.
