Rotating mass is lap time. This genuine TLR outdrive set is the lightened specification — steel outdrives machined to shed grams exactly where they cost the most, in the driveline's spinning mass — so the diff spools up quicker and the car responds harder out of corners. The set contains two outdrives, serving the front and rear diff positions, in TLR's HT specification.

Fitment

Per Horizon's own compatibility listing, this set fits three 1/8 platforms: the TLR 8IGHT-X/E 2.0 Combo race kit (TLR04012), the Losi 8IGHT-XE 4S RTR buggy (LOS04018), and the Losi 8IGHT-XTE 4S RTR truggy (LOS04020) — the race kit and its ready-to-run derivatives share their driveline. As TLR's own support pages advise, confirm TLR242051 against your model's exploded-view diagram (free at tlracing.com) before ordering — the wider 8IGHT family spans generations with differing outdrive specs, and the centre diff uses its own part.

Race-Spares Thinking

Outdrives are wear-and-inspection items on a 1/8 car — dogbone pins gradually notch the cup faces, and worn outdrives cost drivetrain precision. Replace on wear, or fit the lightened spec as an upgrade during a diff rebuild; either way, the diff-service session is the natural moment, fresh diff fluid and all. For the 4S RTR owners: this is also the factory-fit part your car wore from new — a straight genuine replacement after hard bashing miles.
