Overview
Transform your Axial SCX24 into a genuine high-performance rock crawler with the Pro-Line 1/24 Big Bore Scaler Shocks (4) — the ultimate suspension upgrade for UK RC enthusiasts. Whether you're running stock or heavily modified builds, these premium shocks deliver the performance and aesthetics that serious SCX24 owners demand. Just like Pro-Line's legendary 1/10 scale Big Bore Shocks that have won countless races and bashers' hearts across the UK, these miniature versions bring professional-grade engineering to the small-scale crawling scene. If you're looking to elevate your RC car experience and want suspension that performs as good as it looks, this is the upgrade you've been waiting for.
These are not basic stock shocks — they are precision-engineered suspension components designed from the ground up for the SCX24 platform. Pro-Line has miniaturised all the critical features that make their full-size shocks legendary: CNC-machined aluminium bodies, true big bore construction, and polished steel shafts that catch the eye and deliver reliability. The shocks come completely pre-assembled with all mounting hardware included, so you can install them in minutes and start enjoying the performance gains immediately. All you need to add is silicone shock oil, making these one of the simplest yet most impactful upgrades available for your SCX24 crawler.
Ready to run RC cars need ready to run upgrades, and the Pro-Line Big Bore Scaler Shocks are designed for users who want to get straight to the crawling without weeks of tuning and adjustment. These shocks represent genuine value and genuine performance — a rare combination in the 1/24 scale market where many aftermarket parts offer style without substance, or complexity without ease of installation.
Key Features
- CNC Machined Aluminium Shock Caps, Bodies, and Bottom Caps — Every component is precision-engineered from aluminium, not cast plastic or stamped steel, which means superior durability, better heat dissipation, and a professional aesthetic that rivals full-size trophy trucks. The CNC machining process ensures perfect tolerances and perfect fitment, eliminating the play and flex common in cheaper alternatives.
- True Big Bore 5mm Bore Shock Bodies — The large 5mm bore allows significantly more oil volume inside the shock, which is the defining characteristic of big bore technology. More oil means better damping control, smoother compression and rebound, and superior performance across varied terrain. This larger bore is what separates genuine performance shocks from basic replacements, and Pro-Line has engineered it to work perfectly at 1/24 scale without oversizing or compromising the design.
- Leak-Free Double O-Ring Seal — Two precision O-rings on the main shaft create an effective seal that eliminates the oil weeping and leaking that plagued earlier designs. This double seal design provides smooth, low-friction shock action because the seals maintain consistent pressure while allowing the shaft to move freely. This means you'll enjoy consistent performance throughout the life of the shocks, not degrading performance as seals wear.
- Polished Steel Shock Shafts — The visible shafts are polished stainless steel, which adds visual impact and durability. Polished steel resists corrosion better than painted alternatives and maintains its appearance through mud, water, and intensive off-road use. This is a detail that separates premium shocks from budget options, and it's one of the reasons Pro-Line products are instantly recognisable on any RC car UK enthusiast's rig.
- Pre-Assembled and Ready to Use — All four shocks arrive completely assembled with springs installed and all mounting hardware included (M1.4 x 14mm upper screws and M1.4 x 10mm lower screws). You don't need to understand shock building, spring rates, or internal configurations. Simply unscrew the top cap, add 5-6 drops of 20wt silicone shock oil, replace the cap, and compress the shock 3-4 times to distribute the oil. Installation takes minutes, not hours.
- Two Spring Rates Included — The shocks arrive pre-assembled with a standard spring rate that works perfectly for stock and near-stock SCX24 builds. However, Pro-Line has also included a second set of stiffer springs marked with red paint, ideal for heavier vehicles like the Axial SCX24 Bronco with plastic ABS hard bodies. This means you can tailor the suspension to your specific build weight without buying additional parts, and you have the flexibility to experiment and find your perfect setup.
- Universal SCX24 Compatibility — These shocks fit the entire Axial SCX24 range, from the Jeep Wrangler JLU and Chevrolet C10 trucks to the Lexus GX 470, Base Camp crawler, Ford Bronco, Toyota 4Runner, Dodge Power Wagon, and Jeep Gladiator variants. Whether you're running grey, green, orange, white, black, or pink — the compatibility list is extensive and covers virtually every SCX24 model available in the UK market.
Technical Performance
The engineering behind these shocks demonstrates Pro-Line's commitment to genuine performance. The 5mm bore diameter is substantially larger than stock SCX24 shocks, which typically use much smaller bores, and this increase in bore size translates directly into increased oil volume and improved damping characteristics. The double O-ring seal system uses precision engineering to eliminate leaks whilst maintaining smooth operation — a critical balance because a leaking shock loses damping immediately, whilst a seal that's too tight creates friction that prevents proper shock function. The polished steel shock shafts are not a cosmetic detail; steel resists the micro-scratching and corrosion that degrades rubber seals and creates friction over time. The CNC-machined aluminium bodies ensure perfect parallel walls, perfect bore straightness, and perfect bottom cap alignment — tolerances that plastic-bodied shocks simply cannot achieve. The 34mm extended length (eye-to-eye) and 26mm collapsed length (eye-to-eye) with 8mm stroke are optimised for the SCX24's compact chassis while providing genuine suspension travel. Spring length is 20mm, and the inclusive spring rate options mean you can tune for stock weight builds or heavy modified builds without purchasing additional parts. The specification to add only 5-6 drops of 20wt silicone shock oil indicates these are properly engineered for small-scale use — the fill volume is precisely calculated, not guessed. This level of attention to detail is why Pro-Line remains the recognised leader in RC suspension upgrades across the UK and worldwide.

Frequently Asked Questions
- Do I need to be an experienced RC builder to install these shocks? — No. These shocks are designed for users of all skill levels. The hardest part of the installation is simply screwing them onto your SCX24 mounting points using the included hardware. The only additional task is removing the top cap and adding 5-6 drops of shock oil, which takes less than five minutes and requires no special tools or knowledge. If you can change your RC car's battery, you can install these shocks.
- What is the difference between the standard springs and the red-marked stiff springs? — The standard springs (pre-installed) have a softer spring rate and are ideal for stock or near-stock SCX24 builds, providing smooth compliance over technical terrain. The optional stiff springs (marked with red paint) have a stiffer rate and are designed for heavier vehicles, particularly the Axial SCX24 Bronco and other models with substantial ABS hard plastic bodies. Stiffer springs prevent excessive suspension sag under weight and maintain better ride height during aggressive crawling. You can experiment with both spring sets to find which suits your specific build and driving style.
- Will these shocks improve my SCX24's performance noticeably? — Yes, substantially. The jump from stock shocks to big bore shocks is one of the most noticeable performance upgrades available for 1/24 scale crawlers. You'll immediately notice smoother suspension action, better bump compliance, more consistent damping, and improved traction because the shocks aren't bottoming out or bouncing excessively. The larger oil volume means the shocks can absorb impacts and vibration more effectively. If you spend significant time crawling with your SCX24, this upgrade is worth every penny.
- How much silicone shock oil do I need? — You need 5-6 drops of 20wt silicone shock oil per shock, so approximately 20-24 drops total for the complete set of four shocks. A single bottle of silicone shock oil contains far more than this amount, so one bottle will service these shocks many times over.
- Are these shocks compatible with all SCX24 models? — Yes. Pro-Line has designed these shocks to fit all variants of the Axial SCX24 platform, including the Jeep Wrangler JLU, Chevrolet C10 1967 and 1971, Lexus GX 470, Base Camp, Ford Bronco, Toyota 4Runner, Dodge Power Wagon, Jeep Gladiator, and Deadbolt models. Regardless of which SCX24 variant you own, these shocks will fit and function properly.
- Do I need any special tools to install these? — No. A basic screwdriver to tighten the mounting screws is all you need. The shocks arrive pre-assembled and pre-sprung, so there's no disassembly, no spring installation, and no shock building required.
- How do I choose between the standard and stiff springs? — Start with the standard springs that come pre-installed, as these suit the majority of stock and near-stock SCX24 builds. If you've added heavy modifications (armour, lights, additional body panels) or you're using the heavier Bronco or similar ABS hard bodies, try the stiff springs. You can swap between them easily to experiment and find the perfect tune for your specific build and terrain.
