TRD Springs need short stroke shocks?

[jondee86]

If the TRD springs are too short to remain captive when
the suspension is at full droop, you should investigate the
use of "keeper" springs. These are short, closely wound
auxilliary springs that sit on top/under the main spring.

Their only purpose is to keep the spring captive, and under
normal driving they are fully compressed, and act as a
spacer. If the wheels leave the ground and the suspension
goes to full droop, the keeper spring expands to maintain
seating pressure on the main spring.

You will see the keeper coils included as an integral part
and wound on the end of "progressive" springs such as
Jamex and similar. With separate keeper springs you will
need an alignment collar to hold the ends of the two springs
in line. This meens the keeper will butt against whichever
end of the main spring is closed and ground.

Hope this helps
