Fit perfect in my summit

These are well-made drive shafts and the metal seems to be of good quality.
They have the Traxxas style telescoping shaft now not the pined end in a slot.
Make sure you lube the them well and then wipe off the excess after installing them.

Very strong and easy to install. However i did not receive the ones pictured, i got the star spline style which work exactly like the stock ones except made completely from steel instead of plastic. Also the metal tends to corrode if the joints and slider areas are not treated with grease or oil. I use marine grease before installation to lube the joins and slider area and they work perfect.

These are great I have had no problem with them.

Love mine a pain to put in but I have ran with 3s and did back flips jumps went through water mud and works just fine
