This is a set of Lunsford "Quick Tune" Titanium Shock Mounts, and are intended for use with Durango DEX210 and 410 buggies, as well as the DESC410 short course truck. Lunsford Quick Tune titanium shock mounts were invented by racers for racers, and are geared towards the hardcore 'tuning' enthusiast. By removing just one nylock nut, the shock can be quickly moved to any shock tower position. The quality is the same as for all Lunsford parts. Precision CNC machined from domestic 6AL/4V titanium to exact tolerance. These shock mounts have been around since the mid '90s and if you're a diehard tuner, these are highly recommended.
Note: For use on the DEX210 buggy, the Durango "D-Type" Pivot Balls (TDR330036) are required.
