Mack camelback spring end cap rebuild question

[Lmackattack]

This truck did not have the black t.Blocks in the end caps. We bought an atro kit that came with them. Is it safe to install the t blocks To help prevent side to side movement?

 

Some of the mechanics said they've never seen them.However I have. This is on a roll off truck.

Can't think of a reason why you could't, you got a torque multiplier for the u bolts? I think there around 1200 foot pounds.     terry

put the twinkies in the boxes.  all the heavy spec trucks I've worked on and roll offs had them.

Thanks Guys

 

the mechanic put them in. and the bottom caps seam to tighten down fine on the spring.

 

I have seen most of the 38k and higher camelback have these installed but the younger mechanics said they never saw them on the Macks they worked on.. This truck is kinda odd as mack doesent show them on the build sheet and the rears look like 38K or heavier but I honestly dont know what rating they are. It doesent have the transverse rod which I thought all 38k and above had at least one rod on the rear rear axle?

I do know the aluminum caps dont use them but I think they were only used on 34K camelback like my 77' western has
