Hmmmmmm. Good question and needs some explanation. The ratios were perfect. 3b with 10:45 (4.5) diffs, 5 fwd gear. This set up definitely supporting the 32" tyres. The engine was sound and response on throttle was good. Did not actually measure the top speed as the veh still is without a speedometer. The digital speedometer is expected to arrive in a couple of weeks' time so will be further clear. The amazing part was that with the 14:45 diffs, even in pure sand of river suan, the veh was moving in 2H on idle rpm.
