Based on the World Championship design of the 1/8 Buggy red inserts; the EVO Truggy closed-cell red insert has been track-tested and designed for the EVO Truggy tyres. We beefed up the design of the EVO Truggy insert to offer unmatched tyre support while improving handling through the bumps. The EVO closed-cell insert foam is the same quality foam that our customers have come to rely on from AKA. The inserts are water resistant and can handle the abuse that these large truggy tyres dish out.
