FAST DELIVERY

ELIMINATE LUG WEAR
The sleeves expand, conform with the wear pattern and lock the system in place - removing play and redistributing the load.
EASY TO USE
A typical repair with Expander System takes between 30 minutes and two hours, compared to up to a day for line boring and welding.

LUG WEAR AND SLEEVE KITS
Install Expander system directly in the worn lug bores. To deal with ovality above 1.5 mm, you can do a rough line boring without welding down and machining to tolerance. Then install Expander System with oversized sleeves. The rounder the bore, the less need for re-torquing to settle the sleeves into the bore (and permanently eliminate lug wear). If you do not know the severity of the wear, order an X-kit with two pair of sleeves which covers wear up to 4 mm oversize. Any bore size possible.
