Review: The Best RC Vehicle Shock Kits

Choosing the right shock kit transforms an RC vehicle’s handling, traction, and durability. Whether you run a 1/24 scaler, 1/10 crawler, or a 1/16 monster truck, shocks determine ride quality and tunability. These recommendations come from a mix of hands-on testing on varied terrain, analysis of technical specs, and synthesis of expert and user feedback.

How we tested and picked

What we prioritized: durability, damping consistency, adjustability, compatibility, and value. We tested candidates across rock, trail, and mixed-speed runs to evaluate small-bump compliance, rebound control, and impact recovery.

Sources: hands-on runs on real trails and pavement, teardown inspection, manufacturer specs, community feedback from forums and reviews, and cross-checks of materials and measurements.

How criteria affected rankings:

  • Real-world performance weighed most heavily — shocks that kept tires planted and recovered predictably ranked higher.
  • Build quality & materials (CNC bodies, steel shafts, brass/nylon rod ends) determined longevity scores.
  • Tuneability (threaded bodies, spring options, bladder seals) pushed adaptable kits above fixed, pre-oiled units.
  • Value balanced price against included features (springs, assembly, reservoirs).

This produced a diverse set of recommendations for different budgets and platforms.

Best Budget Pick
80mm Metal Dampers

80mm Metal Dampers

Affordable 80mm metal dampers for 1/10 crawlers. CNC-machined metal bodies with a copper sleeve reduce play and improve longevity. Smooth damping and reliable performance make these a solid budget upgrade for Axial, TRX-4 and similar platforms.

RZXYLRC 80mm Metal Dampers — Best Budget Pick

These 80mm metal dampers deliver excellent bang-for-buck for entry-level to mid-grade 1/10 crawlers. Constructed from metal with CNC touches and a copper sleeve to reduce installation gap, they provide consistent, predictable damping without a premium price. Expect solid compression control and improved durability over plastic stock units. They don’t include advanced features like bladder seals or progressive springs, but for drivers wanting a reliable, low-cost upgrade on Axial SCX10/90046, TRX-4, or similar rigs, these are hard to beat.

Pros:

  • Very affordable
  • Metal construction and CNC finish
  • Good basic damping for crawling

Cons:

  • Lacks big-bore design and oil bladder refinements
  • Limited tuning compared to higher-end kits
Premium Choice
88mm Progressive Shocks

88mm Progressive Shocks

Premium 88mm oil shocks with progressive-rate springs and CNC aluminum bodies. Threaded damping bodies, nylon rod ends, and screw-fixed spring retainers give durability and tuneability for aggressive 1/16 monster truck use and high-impact terrain.

$29 from Amazon

INJORA 88mm Oil Shocks — Premium Choice

These 88mm oil-filled shocks are designed for 1/16 monster trucks seeking sophisticated damping behavior. The progressive springs smooth small bumps while maintaining authority on big hits, and CNC-machined aluminum bodies offer precise fit and longevity. Threaded shock bodies allow preload changes, and screw-fixed spring retainers reduce part loss during hard-driving. They're sold without shock oil, so you can tailor viscosity to driving style. If you run a Mini Maxx or similar and want plush small-bump compliance plus robust impact control, these feel premium on the trail and in the air.

Pros:

  • Progressive springs for a wide operating range
  • CNC aluminum construction and reliable retainers
  • Excellent for aggressive driving and jumps

Cons:

  • Higher price point; shock oil not included
  • Slightly heavier than bare-minimum lightweight kits
Best Value for Money
52mm Big Bore Shocks

52mm Big Bore Shocks

Compact 52mm big-bore oil shocks with CNC aluminum bodies and threaded preload adjustment. Big-bore design and bladder seals provide smoother, more consistent rebound—an excellent scaler upgrade offering performance close to premium units at a mid-range price.

$19 from Amazon

INJORA 52mm Big Bore Shocks — Best Value for Money

These 52mm big-bore oil shocks strike an effective balance of performance and price.
