About this part

RPM Caster Blocks for the Traxxas Slash, e-Rustler & e-Stampede are the final link for a complete, bulletproof front suspension from RPM for these trucks. RPM Caster Blocks are redesigned to slim down unnecessary bulk while improving strength and durability in this heavily impacted area. These are stock replacement items. No additional parts or modifications are necessary to mount a set to a vehicle.

RPM Caster Blocks are molded in RPM's trademark blend of ultra durable and super strong nylons and backed by the best breakage warranty in the R/C industry. Each package contains one left side and one right side caster block.

NOTE: RPM Caster Blocks are a direct replacement for the stock Traxxas TRA3632 Caster Blocks. RPM Caster Blocks retain stock Rustler & Stampede 30 degree caster settings. These Caster Blocks will not work on nitro versions of the Rustler & Stampede nor 4wd versions of the Stampede or Slash.

Horible, the part does not even fit, claim's to fit on the car but, when trying it on, doesn't fit, also the part is a different size.

Fit perfectly and word on the street is they are mare durable than the OG traxxas ones. Plus a little flex is a good thing and will prevent other parts further in from damage unlike the aluminum replacements available.

They are not worth triple the cost of Traxxas OEM parts. Please refer to RPM Front Bearing Carrier Set [RPM80372] review. I had interference fit problems with the RPM Products. Other than RPM's Body Savers, I will probably never buy another RPM part.

Ok here is the truth: RPM Caster Blocks are the perfect combination of strength and durability, with just a touch of flexibility to save you when all other parts would have exploded like a parked smart car vs. a speeding 80,000lbs. semi truck. Yes they can break, but in a hammer like way: well used or a completely random fluke. I've never had any issues and they fit better then Mechanics Gloves. Take it from someone who bashes his over-weight, over-powered slash almost daily. R. Rugged P. Performance M. Masterpiece

What reviewers say

Reviewers are divided on this caster block set for Traxxas Rustler, Stampede and Slash. Two reviewers report it fits well and is durable, with some flex that protects other drivetrain parts; one notes it can break but usually only from heavy use or an unusual impact. Two low-rated reviews report fit problems, with one saying the part did not fit the car and was a different size, and the other reporting interference fit issues. One of these also says the part costs roughly triple the Traxxas OEM equivalent. The sample is small and fit experiences conflict.

  • + Fits well on the car (per some owners)
  • + Durable with a useful amount of flex
  • + Fewer breakages than expected, per one heavy basher
  • − Fit problems reported by some owners
  • − Part size differs from expected
  • − Price about triple Traxxas OEM parts
  • − Can break under heavy use or impact
