By Redcat Racing | Published: 2026-11-01
Category: Comparisons
RER19008 is a 12-pack of 10x22x1.5mm washers for the MACHETE; RER43510 is a shock piston and guide set for VERTEX 10 and VERTEX 10 WIDE. Compare fitment before you buy.
Quick answer
They fit different vehicles and solve different problems: choose RER19008 if you need 10x22x1.5mm washers for a MACHETE, and choose RER43510 if you are rebuilding the shock piston and guide on a VERTEX 10 or VERTEX 10 WIDE. Neither part is a universal upgrade for the other model.
Fitment decides this comparison, not price
These two parts do not overlap in vehicle coverage. RER19008 is listed for the MACHETE, while RER43510 is a direct fit for the VERTEX 10 and VERTEX 10 WIDE. That means the first question is not which part is better, but which vehicle you are working on.
Because the catalog does not list cross-fitment, do not assume either part will work on the other platform. If you are servicing a MACHETE, the washer pack is the relevant option; if you are servicing a VERTEX 10 or VERTEX 10 WIDE, the shock piston and guide set is the relevant option.
Hardware pack vs suspension rebuild part
RER19008 is a hardware item: a pack of 12 washers sized 10x22x1.5mm. It is the kind of part you keep on hand for maintenance or reassembly when a washer is lost, damaged, or needs replacing. The pack quantity matters because you get 12 pieces, which is useful if you are servicing more than one spot or want spares.
RER43510 is a complete shock piston and guide assembly for VERTEX 10 and VERTEX 10 WIDE. It is a focused suspension part rather than a general fastener. If your shock needs a piston and guide replacement, this set is the direct-fit option listed for those trucks.
What the catalog does not tell you
The supplied records do not include washer material, torque specs, or shock oil weight recommendations. They also do not state whether RER19008 fits any vehicle other than the MACHETE. Treat those as open questions and verify against your manual or parts diagram before ordering.
For RER43510, the listing confirms one complete shock piston and guide assembly, but it does not specify valving or piston hole configuration. If you are tuning suspension feel, check the part against your current setup rather than assuming it matches a modified shock.
Trade-offs to weigh before you order
- Vehicle coverage: RER19008 is listed for the MACHETE only; RER43510 is listed for VERTEX 10 and VERTEX 10 WIDE only. Match the part to your truck before comparing anything else. If you own neither vehicle, neither part is the right starting point.
- Scope of the part: RER19008 is a consumable hardware pack of 12 washers; RER43510 is a complete shock piston and guide assembly. One supports general reassembly, the other targets suspension repair. Buy the washer pack for maintenance stock; buy the piston set only when the shock needs that specific repair.
- Spare-parts strategy: The 12-piece washer pack gives you repeat coverage for a small hardware item, while the shock set is a single assembly. If you race or bash often, keeping washers on hand is cheap insurance; the shock set is a repair, not a stock item. Check your parts bin before ordering washers you may already have.
