Piston Liner Set Twinspark 85.0mm 10.5:1 DISH DOME ASYMMETRIC SKIRT
$1,147.00 $995.00

NEW SQUISH DISH DESIGN DOME dramatically increases combustion efficiency and power.

NEW ASYMMETRIC FORGING dramatically decreased friction and power loss.  See ad in piston section for details.

CUSTOMER COMMENT:  I am working on my rebuild and admiring the quality of your overhaul kit.  The JE pistons are absolutely beautiful and I'd like to share the specs were spot on.  I couldn't measure any variation between them and they fit the liners perfectly to spec.   The liners were very true with .0003 being the largest variation I could find.  So happy for this.  EE in USA

Valve reliefs are cut with reliefs for large valves and 3mm deeper for most performance cams.


Liners are rebored to 85mm from good core 84mm liners.  They are true to .001" for taper and out of round.  They are fitted to our 85mm pistons at .003" to .0035."

  • Our rebored liners are sold on an EXCHANGE basis.  However, you must send your core liners in advance of shipment.  Sorry, but we have to do this because 90% of customers never return cores.
  • NEW LINERS are available.  Add $320.  No exchange necessary. SPECIFY THIS UPGRADE IN "CUSTOMER COMMENT" BOX WHEN ORDERING ONLINE.  


  • JE forged piston set
  • Standard wrist pins (106 grams, see upgrades)
  • Conventional ring set (see upgrades) 


You should consider the following upgrades:  (Specify upgrades in "Customer Comments" box, when ordering online.)

  • Upgrade to light weight pins (80 grams) for an additional $80.00.
  • Upgrade to Total Seal gapless second ring set for more HP.  $133.50 extra.
  • Upgrade to Total Seal gapless top ring set for even more HP.  $169.75 extra
    (check out HP gains at Total Seal HP Gains).
