FAQ
Does this kit fix grooves on the balancer hub?
Yes. The wear sleeve renews the sealing surface so the new seal can seat properly and stop leaks.
Do I need a special tool?
An installer/driver is strongly recommended to avoid cocking or damaging the seal and sleeve.
Is this for the rear main seal?
No—this kit is for the front crank seal. Rear main seal kits are sold separately.
