Tips on building our Aluminum threaded shocks for the HPI Blitz.

Note: We recommend new ball links from Traxxas when installing these push-rods (Traxxas Part Number: 7028 or 7208X (Steel))
Note: Take extra care when snapping the ball links into the delrin turnbuckle ends.

Note: Wider hex and the stub axles are for the front, the narrower hex are for the rear
note: to install the front, replace the stock axle with the included stub axles and install the hex adapter on it. Remove the set screw and put in the original kit drive pin, and then follow with set screw to secure it in place. A bit of blue lock-tite will help secure the set screw in place. Install drive pins and set screw the same for the rear.
note: Those running ST3652 series aluminum rear hub carriers will have to do the following: Do not use any axle washers. Use Associated drive pins (smaller diameter) especially when using the ST1953 MIP CVD driveshaft kit.
Note: The skid plate mounting blocks are not the same. There are two fronts and two rears
Note: you must use blue lock-tite on the screws that hold the mounting blocks in place to prevent it from vibrating loose during running

Note: The front 17mm hex adapters are the narrower ones. You will need the original bearings and install them into the 17mm hex adapters. You will then use the original front wheel nut to hold the adapter in place on the front axle. A thin walled wrench might be necessary to lock down the front wheel nut
Note: The rear 17mm hex adapters are wider than the front by 2mm for more wider stance in the rear of your SC10 to provide more stability. To install, remove the set-screw, slide the 17mm hex adapter over the rear axle (removing the kit spacers and drive pin) and then install the included drive pin. Once the drive pin is in, re-install the set screw. A bit of blue lock-tite will help keep the set screw in place
Note: You have to readjust your slipper clutch once you install the higher traction 1/8th scale buggy tire to prevent snapping the new drive pins
if you want stronger drive pins, MIP/AE C-CVD rebuild kit’s pin are of the right diameter and stronger in material as well.

Note: The advantage of 1 deg. rear toe-in hub carriers is the added toe-in angle providing more traction in the rear and straight line stability
Note: the set screw is to hold the hinge-pin and the hub carriers in place together and the hinge-pins rotate in the arms only (and not the hub)
Note: The included spacers goes underneath the inner camber link mount ball stud to maintain proper roll center


Note: Use the plastic bushing from the plastic rocker arms to install the aluminum rock arms
Note: Use the original screws to tighten the push-rod, but do not over tighten. Once you feel some resistance, you should stop tightening. Blue lock-tite will help the screws stay secured. Overtightening the screws will strip the rocker arm threads and damage the part
Note: The design of this battery strap is to allow for better lipo battery plug access over the stock plastic battery strap

Note: The advantage of 1 deg. rear toe-in hub carriers is the added toe-in angle providing more traction in the rear and straight line stability
Note: the set screw is to hold the hinge-pin and the hub carriers in place together and the hinge-pins rotate in the arms only (and not the hub) this is to be used with E-clip type hinge-pins that comes with the aluminum a-arms (ST2555 or ST3655, ST3631) or lock-nut type hinge-pin kit (ST3640BK and ST3640S). DO NOT use the setscrew when using the stock hinge-pin (screw into the A-arm type)
