4PCS RC Shock 1:10 Aluminum Front & Rear Shocks Set - Durable Big Bore

In this review of the 4PCS RC Shock 1:10 Aluminum Front & Rear Shocks Set, the bottom line is simple: this kit is for hobbyists who need a heavy-duty, direct replacement for worn AR330550/AR330551 shocks and want a noticeable improvement in damping for off-road driving. The set stands out because it delivers pre-oiled, CNC-machined metal bodies and a big bore design that soaks up rough terrain better than many stock plastic shocks. For anyone running Arrma 1/10 Granite, Bigrock, Senton or Typhon variants, these shocks are a practical upgrade to restore smooth handling.

Key Features

• Direct Replacement: Fits as a drop-in replacement for AR330550 and AR330551 on compatible Arrma 1/10 models, simplifying repairs and maintenance.
• Pre-oiled Design: Shocks arrive pre-filled with oil and use a sealing design that reduces leaks and keeps damping consistent from the first run.
• Aluminum Construction: Metal shock bodies improve durability over stock plastic parts and help the car track more predictably through rough sections.
• Big Bore Performance: Larger shock bore volume provides stronger damping control for heavy-duty off-road use and big jumps.
• Adjustable Ride Height: Threaded bodies allow quick spring preload adjustment so drivers can tune spring force to weight and terrain.
• Complete Kit: Includes two front and two rear alloy shocks with mounts, balls and screws for immediate installation.

Who It's For

This shock set is aimed at Arrma 1/10 owners who want a robust, metal upgrade to restore or improve suspension performance on Granite 4x4, Bigrock, Senton and Typhon variants. It suits drivers who encounter rough tracks, jumps and uneven surfaces and want stronger damping and easier tuning without extensive modification.

Less suitable are casual users who rarely run off-road or those who prefer OEM plastic parts for cost reasons; also competitive racers seeking highly tuned, rebuildable shocks with aftermarket pistons and specific oil choices may prefer a different, fully serviceable shock option.

Pros & Cons

Pros

• Pre-oiled, sealed aluminum bodies reduce initial maintenance and help prevent fluid leaks.
• Big bore design and CNC-machined metal parts provide better impact resistance on rough terrain.
• Threaded body lets you fine-tune spring preload and ride height for different track conditions.
• Direct compatibility with common Arrma 1/10 models makes installation straightforward.

Cons

• Some users report mixed long-term durability around stems, so heavy users should inspect regularly for wear.
• Not advertised as user-serviceable to the level of high-end competition shocks, limiting rebuild options.
