How To: A-arm Molding

How to turn your stock A-arms into show-winning pieces.

Getting ready for a show is always hectic; most people always want to do something new to their cars. During a recent visit to Homies Hydraulics in Paramount, California, we were asked if we wanted to document a pair of A-arms being customized for a show car. Always on the lookout for the latest trends to hit the show circuit, we said sure. A pair of stock A-arms received a custom touch within a few hours.

Homies owner Anthony explained how you gain a few "hidden" benefits when you mold A-arms, including how they're better able to take the abuse that is caused by the hydraulic pressure. Another benefit is that the A-arms looks like show-winning pieces with a cool custom look. Let us show you how the pros at Homies Hydraulics customize A-arms using pieces from the Original Parts Group. You may want to do the same to your A-arms.
