These locking shock spring perches follow design queues of TKR6140 with one change, the shock perch has been lengthened. The tall spring perch helps prevent the shock spring from unseating and also prolongs the shock boot lifespan. The shock boot is now protected inside the spring perch and prevented from touching the moving spring.

TKR6140B includes 4 shock rod ends, 4 tall spring perches, 4 10mm set screws and is compatible with all generations of the SCT410, EN48, ET48, NB48, NT48 and EB48SL vehicles.

Never lose a shock spring again with these locking shock spring perches and rod ends. This design mates up perfectly with the Tekno captured shock boots (TKR6143, TKR6144, TKR6145) to ensure your suspension stays consistent throughout any race or run. The spring perches rest on a shelf around the rod end instead of directly on top of the rod end. The result is less interference from the shock boot and absolutely no sacrifice in up travel. Each spring perch / rod end is secured by an M3x10mm set screw (TKR1605).

NOTE: Requires the use of captured shock boots (TKR6143, TKR6144, TKR6145). Shock boots should be installed before the rod ends are attached to the shock shaft.


  • Locking design ensures you never pop or lose a spring.
  • No sacrifice in suspension up travel.
  • More consistent suspension action.
  • Durable composite construction.
  • Extended length shock spring perch.
  • Compatible with EB/NB/ET/NT/SCT Tekno RC vehicles.

Tekno RC Locking Shock Rod End & Spring Perch Set (Revised, 16mm Shocks)
Strongly recommended upgrades for all TEKNO vehicles.
I use them on SCT410.3 EB48.3 and ET48.3

The revised tall design helps the spring to stay in the right place from huge jumps and crashes.
It is a great investment .)
