Question Slash 2wd parts problems

I would like to know of any problems with stock Slash parts. All parts.

Caster blocks are a known weak point on all 2wd Traxxas vehicles that use that style of front end (i assume you mean the 2wd just by your other thread). Shock caps are a problem spot as well. Aluminum replacements are the answer to both problems.

shock shafts tend to bend fairly easily too, no known fix for this fundamental design flaw with the HCG chassis, the LCG chassis is far less prone to bending shock shafts

TiNi shafts all but eliminate this issue. We don't bash, but my HCG Sleeper Slash has a lot of successful races under its belt with no bent shafts

Many folks still report bending and/or snapping their TiNi shafts too:

The stock shafts must be made out of the same coat hangers they make hinge pins and king pins out of. When steel is hardened, it becomes less pliable, so it is easier to break. Nothing is totally bulletproof, but 3 trucks with a few years of racing on them with no bending or breakage.

That's odd, I used to bend stock Ultra shocks on my Emaxxes quite often but those were 12 lb. trucks and used 100wt. shock oil so it was no wonder why they would bend. I have never had an issue with the shocks on lighter vehicles bending like that. I always thought that the lighter oil used in the Slash was one of the factors that helped keep the Ultra's together, coupled with their considerably lighter weight. How hard of a crash did it take to bend them like that?

That's not my photo. I've bent one shock in an HPI rock crawler.

Yeah, I was actually asking N4S what caused the damage.

Ken, have you actually broken any parts on your slash yet? Is there a particular part that you are worried about breaking? This might help us understand what you are looking for.

I haven't broken anything yet to my surprise. Actually I'm upgrading a new 2wd Slash. I have installed lcg chassis and Traxxas brushless motor w/esc. Now I want to start upgrading to alum parts. This isn't for racing, just something I want to do. I would like to start with the weakest parts first and go from there. Hope you understand.

I gotcha. Upgrading to aluminum in some key areas can help, but be cautious of using it everywhere. It will add weight and once bent it stays bent and can break other parts in the process. In a wreck the aluminum parts will transfer the force into other areas of the chassis whereas plastic will give and return to its prior shape. Aluminum arms are a great example here. A crash that would cause a stock plastic arm to bend and flex will cause an aluminum arm to send that force into the bulkhead and incur damage there. The caster blocks and steering knuckles are a great upgrade to a stock slash as well as rear hubs. On my trucks I use a lot of RPM plastics and the aluminum casters and knuckles and have had no issues with durability.

Agreed. But I've actually had good luck with the RPM bearing carriers. Aluminum c-blocks are a must though. The Proline Protrac kit is a good package for the money also. Stronger shock towers, arms and rear bearing carriers, plus turnbuckles and a set of Losi offset wheels to mount race tires on. Only breakage in 3 years was one turnbuckle, and a rear tower after being run over by a truggy in open practice

I really like the RPM carriers that I have on a few of my trucks and have yet to have any problems with them. I use alloy knuckles on my 4x4's (I got a good deal on a combo kit with caster blocks, steering knuckles and rear hubs) and have had problems with those either, so I can say that they are both viable options.

I would love to try the ProTrac kit on my LCG 2wd chassis someday. I used their Performance Suspension Kit on my T-Maxx back in the early 2000's when Maxx racing was still popular and it was a night and day difference in both performance and durability. I have seen other trucks running the ProTrac kit and it is impressive how much better they handle.
