B6.1 67mm Light Bone Set for Pin Drive made by MOD Speedshop.   

This product is for B6.1D racers wanting to shed some weight for 17.5 racing on dirt.   Offered pre-assembled in cooperations with modspeedshop.com, these are direct compatible with B6.1 series kits.   67mm bones also work for B6 racers that have converted their B6 series to use 67mm axles/inserts.  2mm longer than the kit 65mm bones, the long 67mm bones can move through the range of suspension travel with less angle mis-alignment.  This translates to less bind on power and more rear grip as the suspension works under load instead of locking out due to the drivetrain.

The 2 piece bones utilize a lightweight aluminum pin drive shaft mated to proven MIP steel CVA yokes.   The bones can handle the power of both Modified and 17.5 racers.  Pin drive bones work with the kit B6.1 steel outdrives, or B6.1 pin drive Bi-Metal MIP differentials (see SCH1259 pin drive B6.1 Bi-Metal diff) and have a positive driving feel, locking the rear end in on-power.    Many racers like the feel of pin drive shafts because they enable the buggy to set into the corners and carve without getting upset by small steering inputs or bumps.  With the MOD Light Bones, racers get the best of both worlds, light weight and stable handling.

Features:

  1. Rotating weight savings. 7.5 grams vs 11 grams for steel kit units.
  2. Rebuildable 2 piece design, change either the aluminum bones* or steel MIP yokes.
  3. Pre-assembled in cooperation with MOD and MIP.
  4. 67mm length mates with option Schelle long bone axles or using the "hub mod" to shift the axle outward using aluminum hubs.
  5. Works for 17.5 or 13.5 motors on dirt with slipper clutch.   Don't use in Mod on slicks/clay but on lower grip they have been OK with a slipper.
  6. Carpet:  17.5 slipper is OK.  17.5 Lockout will work, but the part life is reduced so they may only last 1-2 weekends.  Not recommended for Mod on turf/carpet, they will break on the 1st run.
  7. For added security, run an o-ring up-travel limiter on your rear shocks.
  8. Fits B6.1D direct fit.   Fits B6 series with Schelle or Associated aluminum option rear hubs, 67mm axle modification req'd.
