Default TC3 FT aluminum shock tops w/Lunsford "quick tune" shock mounts?

My understanding of the point of bushings is that the goal is to avoid metal-to-metal contact of same-kind metals. (e.g. in 1/1 scale car engines, brass bushings between steel moving parts is typical.)

So if I use

Lunsford 7311 "quick tune" Titanium Shock Mounts:



Associated 1598 blue aluminum shock tops:


then is it a bad idea to use the

Associated 1780 blue aluminum bushings?:


I could stick with the standard

Associated 6473 plastic bushings:


but I was hoping to use delrin rather than plastic bushings.

The solution I'm thinking of is:

RPM 70181 Delrin Pivot Balls


which have the right I.D. for the Lunsford 7311 but the O.D. of the balls is too large to fit in the shock tops. My plan is to ream out the I.D. on the shock top to fit the O.D. of the RPM balls, allowing just enough slop for free movement.

Bill....For this low movement area of the car, you can get away with almost anything for a while...... but like you already knew,the aluminum cap against the aluminum bushing will slowly fight each other and wear, in time causing slop that you can't tighten away.........IMO the longest lasting and most frictionless combo is the aluminum cap and the stock black bushings.......all of the delrin bushings iv'e used in this area gave some unwanted slop after a couple runs........ Don't make too much work for yourself on shock caps

the delrin pivots are for the bottom rod ends of the shocks, not sure if they would work as a shock bushing
