FAST DELIVERY

Rapid lead times for customized aftermarket parts. If we don’t already have the pin you are looking for, we’ll design it for you.

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.
