Terrain Tamer DKCP23 Diff Overhaul Kit 4.3R Rear – Crown & Pinion + Flange (FZJ105,HZJ105,HZJ78,HZJ79)

Upgrade the driveline strength and reliability of your Toyota LandCruiser with the Terrain Tamer DKCP23 Diff Overhaul Kit 4.3R Rear. This is a full, professional-grade rear differential rebuild kit  covering crown & pinion gear, flange, bearings, and all essential gaskets and seals. Designed for serious 4×4 use, remote travel, mining, heavy duty work or off-road adventures, this kit gives you the peace of mind of a “fresh” differential from the ground up.

This isn’t just a bearing kit — it’s a complete overhaul. Terrain Tamer’s decades of 4WD expertise mean the DKCP23 is engineered to meet or exceed factory specs (and in many cases, surpass them), giving you durability under load, long-term reliability, and rock-steady performance even when pushing hard.

Whether you’re rebuilding an old axle for reliability or upgrading for peace-of-mind before a long expedition, The DKCP23 diff overhaul kit gives you everything you need in one comprehensive package.

Ideal for rebuilds where you want to eliminate as many “what if” weak points as possible.

Diff overhaul kit Includes / What You Get

• Crown gear & pinion assembly (4.3R ratio)

• Flange (for output shaft)

• All required bearings (pinion bearings, carrier bearings) — high-quality Japanese bearings.

• Seals and gaskets (including diff housing gasket, pinion seal)

• Drain / fill plug washers / crush washers / general hardware as required for reassembly

Applications / Compatibility

• Designed for rear axle rebuilds on Toyota LandCruiser models requiring 4.3R rear differential ratio (check your axle code for compatibility).

• Ideal when doing a full diff strip-out, rebuild, or upgrade especially when original ring & pinion are worn, noisy or suspected of damage  or when you want to avoid future diff trouble on heavy-duty/ off-road use.

Recommended Use & Benefits

• Full rear axle diff rebuild kit— not just bearings: renews crown & pinion, gearbox flange, bearings, seals and gaskets for a “like-new” diff.

• Gives maximum reliability under load — good for towing, off-road, mining or heavy use (which means it fits the usage style typical of 4WD builds like what you do for clients).

• Saves time, avoids sourcing individual components — one complete kit.

• Peace of mind: using high-quality bearings and full rebuild parts aimed at heavy-duty and harsh Australian conditions (terrain, load, heat, dust, etc).

Notes / Warnings / What to Check

• Verify that your axle uses 4.3-ratio and that the diff is compatible with this kit before ordering (DKCP23 is a 4.3R rear kit).

• Because this is a full diff overhaul kit including crown & pinion you typically need proper tools and setup — bearing preload, backlash setup, measurement tools, torque specs etc. (Not a “bolt-on” diff cover gasket job).

• Always inspect bearing surfaces, housing and axle internals when building — even though it’s a full diff overhaul kit, internal housing wear or axle shaft condition may still require attention.
