Durable aluminum knuckle arms for HPI E Firestorm

Will these knuckles fit the stock HPI suspension without modification?

Yes. GPM EF021 knuckle arms are made to match the HPI E Firestorm mounting points so they install using the factory suspension hardware.

Do I need a stronger servo when I fit aluminum knuckles?

A mid-torque digital servo is a good match for aluminum knuckles to preserve steering precision, though stock servos often work fine for casual running.

How should I maintain these knuckles?

Check mounting bolts for tightness after the first runs and inspect for wear periodically. A light lubricant on pivot points prevents squeak and corrosion.
