Rival MT8/SR7 Hoonigan shock shaft dimensions?
Hi there,
Would anyone who owns an AE Rival MT8 1/8 or SR7 Hoonigan 1/7 able to measure the diameter of the shock shaft for me please?
I'm midway through restoring my old SC8e, which uses 4mm shock shafts and I'm seeking to find shock shaft seals and o rings that may fit. Nowadays it seems basically every current 1/8 buggy/truggy uses 3.5mm shafts, and I'd rather keep the 4mm for durability reasons, especially as I have the TN coated Factory Team shafts!
The SR7 (which I found out shares the same shock rebuild kit part number as the MT8, 25920) shock shafts look beefy just from online images, I suspect they may be 4mm.
I know the HPI Vorza uses 4mm shock shafts, but it would just be nice to keep everything AE parts if possible.
Thanks in advance!
