Reply to "Heim joint"

The use of heims in suspensions is usually limited to racecars-only, for two reasons
1)- the constant pounding of street driving with zero maintenance distorts & wears loaded bearing surfaces if the heims you choose has them. Two-piece all-metal ones might have longer lives than those with teflon or bronze liners. Pay close attention to the way your car feels each time you drive and be prepared to change the heims regularly when an inspection shows looseness. Heims are NOT repairarable.

2)- dirt, water, road-swarf etc gets inside and causes binding & more wear. There are heim-seals specific to each size that can help this. Speedway racing in NE or Pegasus Auto Racing in WI both sell these seals very cheaply.

The main Pantera vendors sell these a-arms and use very heavy-wall tubing in their builds- often of 4130 steel. Tricky to weld & hard to bend. Don't be surprised if your fabrication weighs more than the entirely adequate stock a-arms. A journeyman welder should be doing this work- your life depends on the integrity of the welds (and threads). Good luck.
