A simple product in the sharpetooling range is this 2 inch Load proportion Valve Spacer to suit 40/6075/76/78/79 series Landcruisers.
Please Note - 70 series Landcruisers produced after 'Late 2016' are optioned with ABS and Stability Control. Research shows that some of these late model vehicles do not have a LPV fitted. Please ensure your late model cruiser has a LPV before buying this product.
This spacer is to be fitted when your landcruiser has up to a 2 inch lift kit installed. When your rig has a lift, the rear brakes are not balanced properly due to the Brake Load Proportion Valve sensing the car is sittiing 2 inches higher than normal.
Essentially the car thinks that you are empty and that less brakes are required on the rear.
To get your brakes working effectively again, simply fit this spacer.
