Info on spring spacers

[Ivan141]

Those spacers are made by TRD, so I guess they'll be safe enough. Polyurethane doesnt seem like a likely candidate though. There is just to much force and rubbing going on, it would tear apart in no time. I belive aluminium is the way to go. You could drill small holes through the spacer and attach it to the spring using tiewraps or something like that, or put some sort of rubber on the top that creates an interference fit with the spring.
