hot racing shock bore size

[yellowufo]

Anyone ever measure the bore size? It would answer alot off questions as to why the shocks r softer after switching
bodies.......

Sounded like 7.62 my red piston are a little bit bigger

Your caliper talks????

Stock red two hole (.500) piston is 7.6mm wide stock bore is 7.80mm = .2mm differance, perfect.

On my hot racing shock the bore size is 7.95mm that = a .15mm differance when using the stk piston
Not perfect or even close
That lets lots of blow by and a piston rod that will wobble back and forth.

Lesson to learn if all the hot racing shock bodies r 7.95mm your shocks will be way softer then your stock
Shocks i have read many a story of this happining with confusion being the end result.

Measure your hot racing and all shock bodies to know what you have. Before you waste your time.

I just got another set of HR Bodies in the mail, and I have a set of new red pistons. I got pretty much the same numbers, 7.5mm pistons, 7.9mm dia on the HR Bodies. I used a 50/50 mix of 70WT oil & 10K Diff oil to stiffen them WAAAY up for my boy's Grave Digger. I also used this setup on my Mini Slash 4X4, & Boss Mustang with stiffer springs.

thanks as you said you can overcome the oversize bore by mixing up some thicker mixture just wish
The cut them better the shaft wobble will cause leaks overtime and may cause binding

I haven't had any shaft wobble, although at first I had oil leaking down the shafts. Instead of using the new o-rings from the HR Bodies, I used the original stockers with the HR spacer. No leaks. No wobbles.

I use the stock blue seal -stock spacer -blue seal then a hr seal and that works pretty good no leaks
