These Altmount Kits by Balmar offer the opportunity to install a larger alternator than would otherwise be possible. This kit 48-NSP-100 is for the Nanni N4.6, N4.85 and N100. There are kits designed to fit many engine models, the list expands every day so if you don't see your engine listed do give us a call.
Alternator upgrades using a single drive belt are limited by the amount of power that can be transferred by the belt but using a serpentine belt considerably increases the possibilities. The kits include a set of serpentine pulleys to go over the crankshaft and water pump pulley and replace the alternator pulleys and come with a matching serpentine belt. They are sold for specific engine models only. The alternators need to be purchased separately. If you order an alternator with a kit it will come with the appropriate pulley pre-installed. Installation is relatively easy. The kit comes with two 44.5" K6 belts but purchasing an additional spare belt is recommended. This kit requires an alternator with a K6 pulley
