Harley Rocker Boxes, Rocker Arms and Covers

The rocker box is where the top end gets noisy and where it likes to leak. We carry complete rocker box sets from V-Twin and Drag Specialties, Rocker Locker noise reduction kits, Feuling breathers and Gorilla rocker shafts, S&S rocker shafts for M8, and dress-up covers from Performance Machine and EMD.

What You'll Find Here

  • Rocker boxes: complete sets for '99-'17 Twin Cam and '86-'03 Sportster
  • Noise kits: Rocker Lockers for Evo, Twin Cam and '07-'22 Sportster
  • Shafts and bushings: Feuling Gorilla shafts, S&S M8 shafts and OE-style bushings
  • Covers and hardware: M8 rocker covers, breather kits and 12-point dress-up bolts

A top end job is the time to sort everything up there: adjustable pushrods, cams, cylinder heads and a fresh gasket kit. See all engine parts.

Not Sure It Fits?

Evo, Twin Cam, Sportster and M8 rocker parts don't cross over. If you can't tell whether something fits your bike, hit us up with your year and model and we'll check it before you order.
