SCX10 Rear upper link mount risers made for superstrong NYLON
These parts will allow you to raise up the chassis side rear upper link mounting points to give you better anti-squat characteristics (see below for a tech answer on why this is good...)
Weighs only 3 grams for the pair!
Improves performance on uphill climbs
Works with stock SCX10 Chassis and skid, no modifications at all necessary
Raises your mount up 15mm and back about 3mm, so it should be compatible with almost any existing setup. No need to change out your links!
The only modifications I recommend would be to drill the skid mounting hole where the upper link attaches to 1/8" or 3mm so that you can screw through that into the riser. This will require (2) 8mm M3 screws, not included.
Here's some more info on why this is a good thing for your rig:
With the raised COG and often vertical climbs these rigs encounter, the stock squat set-up actually makes it easier for the front suspension to unload and allow the vehicle to flip over backward. By simply changing the mounting point, this turns the geometry to an anti-squat set-up and when under power, the rotation of the axle actually raises the back end of the vehicle, providing a forward bias, helping you get up and over that steep climb.
