The front Struts from the 1994-96 Vmax 5-600cc sleds will give you 2" more travel ! You need the longer shock covers, springs and aluminum knuckles along with the struts. You can find them fairly reasonable on E-bay, any parts forum or salvage yards ! I bought a set of brand new(rare) Genuine Yamaha GYT Kit struts off of E-bay that were an upgrade for the Vmax 5-600 sleds with adjustable dampening, rebound and slightly longer travel for $75.00 !

The 94-96 Vmax 5-600cc sleds had 7.2” of travel although a inch or so was used up in set in or suspension sag (Bender made a kit to get back and use this lost? Travel. The struts would work for the Exciter, Phazer II’s or any Yamaha that had enough clearance for the longer Strut covers. I’m not sure on the Vmax4 how much travel they had ?
Yamaha had a T.S.S. GYT Kit that had adjustable damping along with adjustable preload. Yamaha part # SMA-8CA91-10-00
