Benzyl halides react via SN1 and SN2 with equal probability..unless the reaction conditions are altered..

SN1: the benzyl carbocation formed in the rate determing step of the reaction is stable as the positive charge generated is spread over the ring.

SN2: recall the intermediate of the mechanism. The transition state involves a trigonal planar state where the leaving group and the nucleophile occupy the opposite lobe of the unhybridised p orbital lobe of the central C atom. In case of benzyl halides the ring es being planar to this p orbital can conjugate easily by delocalising the pi es..stabilising the transition state..and hence reaction occuring with equal probability via this pathway..

SN1 reaction depends on carbocation stability. And benzylic and allylic carbocations are very stable carbocations due to resonance.
Beacause their carbocations are stabilised by resonance . It’s easy for the nuclwophile to attack the carbocation and form products.
Benzyl and allyl carbonations are stable due to resonance hence benzylic and allylic halides undergo SN1 reaction.
