Upgrade Sets for Serpent Cobra Buggy
Serpent have introduced a number of upgrade sets for their Cobra buggy. The use of larger, stronger bearings on all four corners of the car makes the Cobra even more reliable. The new diff-coupler and pinion system with two larger bearings also improves reliability. This feature has already been integrated into the Cobra Be, which has these features from the outset.
The four main upgrade sets are:
#600502 Upright set with larger bearings referred to as v2
#600503 Steering blocks set with larger bearings referred to as v2
#600524/600505 New diff pinion system with larger bearings. Front and rear referred to as v3 with v2 central shaft
