# All seal heads are made from 6061-T6 Aluminum to save weight.
# All Rear Shock Seal Kits have an air bleed hole. This helps remove air from the oil reservoir during seal head installation.
# Oil seal utilizes a double lip design and a low friction elastomer. This gives the seal head additional dirt exclusion and yet maintains a low drag (low friction) seal.
# The dust seal utilizes a spring type exclusion seal to maintain constant pressure and assure good dirt and contaminant exclusion over the life of the seal head.
# On early Yamaha seal heads/Yamaha Blaster seal heads we have done away with the multi piece design. This makes installation quicker and easier
