Sparko is dropping the grub screw from shock mounting on its F8 buggy. The company has introduced 7075 hard-anodized threaded shock pins that mount directly into the shock, a setup it calls simpler and more secure than the previous hardware.
According to Sparko’s product announcement, the pins are machined from lightweight 7075 aluminum and get a hard-anodized finish for wear resistance. Because they thread straight in, there is no grub screw to fuss with. Sparko says that means a cleaner install and more consistent handling, run after run.
Sparko also engineered the pins with vibration in mind. The left-side pins are reverse-threaded, which the company says keeps them from loosening from vibration. The hard-anodized coating is described as wear-resistant, while the 7075 material is called strong, light, and race-ready.
The pins carry part number #F840910P. Powerhobby handles US distribution for Sparko products.
Built for the F8 platform
The pins are designed for the Sparko F8, a 1/8 nitro pro buggy that Sparko says was engineered with professional-level racers in mind. The company says corner speed drove every design decision, while build quality and durability stayed uncompromising. Sparko calls the F8 a future-focused platform, with optional upgrades and performance parts developed through testing by its factory drivers and engineers.
The F8 name, according to Sparko, references one of the most sophisticated fighter jets ever built, reflecting the precision and advanced engineering inside the buggy.
The F8’s standard suspension already includes 16mm bladder-type big-bore shocks with gold titanium nitride-coated shafts and 7075 hard-anodized aluminum shock bodies, so the new pins match the material and finish used elsewhere in the suspension. The shock hardware also includes pre-marked spring collars for height adjustment and a lower spring retainer screw that keeps the spring and retainer locked to the lower ball cup. Stainless steel front and rear quick-release lower pins make getting the shocks off the car quick work.
Sparko’s F8 spec sheet continues beyond the shocks. Up front there is a 16° aluminum C-hub for sharp steering response, a rigid front upper arm, and an aluminum steering bellcrank for a slop-free feel. The drivetrain is a three-differential design with 43/13 ring-and-pinion gears front and rear, a 46T spur gear and 13T pinion at the center, a dogbone center driveline, and universal driveshafts at the outdrives. A molded electronics tray can be fitted with optional grommets to help keep dust and moisture away from the receiver, battery, servo, and AMB transponder.
The F8 also comes with two sets of front and rear anti-roll bars: 2.3mm and 2.5mm front bars plus 2.6mm and 2.8mm rear bars, with other rates offered as optional parts. The suspension arms use carbon inserts for extra rigidity, and the rear arms can be run in long or short configurations with adjustable offset inserts. Sparko also gives the F8 body and its 3-in-1 rear wing system a role in the tuning package; the wickerbill can run with holes, without holes, or removed.
The F8 line isn’t just nitro anymore. Powerhobby lists the F8E Electric Pro Buggy Kit as the electric version of the F8 Nitro Buggy. That kit is described as a 1/8 brushless buggy with a multi-configuration battery mount, accepting 2x 2S stick or shorty packs or brick 4S or shorty packs. Its feature list includes alloy caster blocks, steering knuckles, a carbon fiber top plate, and center diff plates.
The new threaded shock pins are one more option for a platform Sparko says is built to evolve. Sparko points to SparkoRacing.com for more information on the F8 and its parts.
