This is a COMPLETE rebuild kit for GARRETT T3/T4 Hybrid turbos. This kit comes complete with all of the correct bolts and clamps for a T3/T4 Hybrid, not just the bolts for one or the other. This is for a T3/T4 turbo with a dynamic seal on the compressor end as most hybrids are. We have the carbon seal kit available if that is needed for your application. We also have T3/T4 high performance kits available.
