DRIVELINE & BRAKES
HARROP ENHANCED FORD PX RANGER Two differential upgrades for enthusiasts are now offered by Harrop Harrop Engineering has taken its mission to deliver industry leading powertrain and driveline products to the Automotive Aftermarket and applied it to the popular Ford PX Ranger platform; creating a suite of performance products for enthusiasts to relish. Harrop’s engineering and design prowess were recognised by 4x4 Australia when its PX Ranger development vehicle was crowned the inaugural 2016 Custom 4x4 of the Year, as voted by readers. This achievement and the continued sales performance of the PX Ranger nationally was a key driver for further product development by the Harrop Engineering team. Fast forwarding to today, Harrop now offers two differential upgrades for enthusiasts with a helical gear design Truetrac LSD and industry leading ELocker. The Harrop Eaton Truetrac differential operates as a standard or open differential under normal driving conditions, allowing one wheel to spin faster or slower as necessary. When a wheel encounters a loss of traction or the terrain changes, the gear separation forces take effect and transfer torque to the high-traction wheel.
The helical-shaped gears mesh with increasing force until wheel spin is slowed or completely stopped. When the vehicle exits the low traction situation, the differential resumes normal operation.
with performance upgrades in particular with higher boost applications.
Harrop also offers an electromagnetic actuated ELocker, its market leading selectable locking differential for off-road use.
The Harrop Charge Air Intercooler features cast aluminium tanks welded to the core for a robust solution designed to handle the higher boost loads without the fear of cracking the plastic tanks or leaking through the seal area of the plastic tank and aluminium core.
Similar to the Truetrac the ELocker operates as a standard or open differential under normal driving conditions but is switched activated to a fully locked differential, capturing 100 percent of the available torque and sending it equally to both ends of the axle as required.
Harrop’s inhouse testing on its Ford PX Ranger development vehicle saw Intercooler temperatures remain constant over extended test cycles, compared to the OEM intercooler which had over a 65 percent increase in temperature (from 33 degrees Celsius to 55 degrees) over a 100 second drive cycle.
To complement the differential range, Harrop also supplies Diff Rebuild Kits for customers requiring an overhaul at the time of upgrade.
Harrop’s Charge Air Intercooler will also be available to suit the range of 2.0L powered Ford Ranger and Raptor models late in 2021.
Further to this, Harrop has recently developed a Charge Air Intercooler Kit for the PX Ranger with a 28 percent larger frontal surface area and 75 percent thicker core than the OEM unit.
Harrop Performance and 4WD products are available for order from stockists and dealers across the country.
This upgrade addresses a known deficiency in the factory plastic tanks which can fail on vehicles

NEW SPINDLE GREASING TOOL From Terrain Tamer
Terrain Tamer explains that it is not uncommon for the inner spindle / CV driveshaft bearing / bush to fail prematurely, due to being starved of lubricant, as it cannot be greased without the spindle being removed. The new Terrain Tamer Spindle Inner Bearing / Bush Greasing Tool, or ‘Spindle Greasing Tool’ for short, has been created as a solution to this problem.
and bearing adjustment lock nut, the tool fits on the threaded end of the spindle.
The tool allows greasing of Toyota spindle bushes, without needing to remove the spindle or wheel hub.
Compatible with all Toyota threaded spindles, Terrain Tamer says the bearings’ longevity is greatly extended when using the Terrain Tamer Spindle Greasing Tool.

Grease is then pumped between the spindle and the drive shaft. A rod inserted in the steering knuckle filler plug hole will show the grease level. Terrain Tamer says molybdenum grease is recommended for this application.
