VS4-10 vs 他Vanquishプラットフォーム：最適なビルドの選び方

クイックアンサー

まずは VS4-10 ビルダーズキット - ストレートアクスル VFDトランスミッションとF10ストレートアクスルを1つのボックスで手に入れたいなら、これを選びましょう。Currie F10 ポータルアクスルプラットフォームを求めるなら、VS4-10 Ultra または Phoenix を選びましょう。 Currie ポータルオーバードライブギアセット (20/28) は実験ではなく純正交換部品です。VRD1 ケージプラットフォームは、Phoenix ボディとバンパーエコシステムを中心に組み立てる場合にのみ選んでください。決定要因はボディではなく、アクスルタイプとトランスミッションファミリーです。

Vanquish は、ブランドは同じでも部品を共有しない複数のクローラープラットフォームを販売しています。VS4-10 ファミリーはストレートアクスルとポータルアクスルのビルドに分かれ、VRD1 ケージは独自のボディマウントとバンパーハードウェアを採用しています。つまり、正しい質問は「どのキットが最善か」ではなく、「自分の走行地形と手元のパーツがどれをサポートしているか」です。

この比較は、カタログに実際に記載されている内容（ドライブトレイン構成、アクスル設計、どの交換部品がどのキットに適合するか）に限定しています。仕様が公開されていない場合は、互換性を勝手に想定せず、注文前に確認すべき判断事項として扱ってください。

ドライブトレインとアクスル構成：本当の分岐点

VS4-10 Builders Kit - Straight Axle は、Vanquish Products VFD トランスミッションと F10 ストレートアクスルを組み合わせ、ISD10 ドライブシャフト（機械加工された CV スタイルのジョイント）で接続します。成形された F10 ストレートアクスルは、ハイクリアランス設計でディファレンシャルハウジング（パンプキン）を小さくし、Cハブとナックル周りの強度を高めています。この組み合わせは、アクスルハウジングを岩の角に引っ掛けずに滑らせたいビルドに向いています。

Portal builds take the opposite approach. The Currie F9 and F10 portal axles carry a 1.67:1 gear ratio as delivered, with the Currie Portal Overdrive Gear Set (20/28) dropping that to 1.4:1. Portal boxes add ground clearance at the wheel, but they also add parts and adjustment points. Neither layout is universally better; they simply fail in different places on the trail.

• Straight axles: fewer moving parts, simpler to service, less clearance under the diff.
• Portal axles: more clearance at the wheel, more gear interfaces to maintain.

Where each platform's parts actually fit

Fit is where platform comparisons get practical. The VFD Light Weight Aluminum Motorplate fits VPS09003 and VPS09004 Pro Kits and the VPS10152 VFD Transmission Kit, so it crosses between straight-axle and portal VS4-10 builds that use that transmission. The VFD Sintered Gear Set is narrower: it is a replacement set for the VPS10152 VFD Transmission Kit only.

On the portal side, the Currie Portal Overdrive Gear Set (20/28) is listed for Vanquish Products SCX10-II Portal, VS4-10 Ultra, and VS4-10 Phoenix F10 portal axles, and it is the stock replacement for the VS4-10 Ultra and VS4-10 Phoenix (VPS09007) kits. The VRD1 Rear Cage Parts are a separate ecosystem entirely, built for VPS10184 body mounts, the Phoenix body, and VPS10181 bumpers and sliders.

• Check the kit number, not just the model name, before ordering a drivetrain part.
• Cage, body, and bumper hardware rarely crosses between VS4-10 and VRD1 builds.

How the VS4-10 buying decision changes with terrain

If your local trails are loose, steep, and full of ledge steps, the overdrive option on portal axles is the meaningful lever. Vanquish lists the 20/28 gear set as helping with steep climbs and turning radius, and it can be run in the front axle only or in both axles. Front-only keeps the rear wheels driven at the stock ratio, which changes how the truck pulls under throttle.

If your terrain is technical, low-speed rock with tight lines, a straight-axle VS4-10 keeps the driveline simple and the parts count low. You give up wheel-level clearance and the overdrive tuning option, and you gain a shorter list of things to check when the truck starts making noise.

• Run overdrive front-only for a noticeable steering and climbing change without altering rear axle behavior.
• Confirm whether your kit already ships with the overdrive set before buying it twice.

Electronics and body choices are not the deciding factor

Lighting and body hardware are easy to swap later, so do not let them drive the platform choice. The Incision Series 3 Light Kit is designed for the VS4-10 Phoenix, the VS4-10 Origin Classic, and its included molded front inner fenders, with molded front light buckets, a heatsink LED, red tail lights, and white front and rear inner fender rock lights. It fits those bodies specifically, not every Vanquish rig.

The same logic applies to the VRD1 Rear Cage Parts, which exist to support the VRD1 body mount and Phoenix body combination. If your build plan starts with a body you already own, work backward to the platform that supports it rather than forward from a kit sale.

• Buy lighting and cage parts after the platform is settled, not before.
• A light kit that fits one Vanquish body may not fit another without modification.

Trade-offs to weigh before you order

• Straight axle vs portal axle: The VS4-10 Builders Kit - Straight Axle uses F10 straight axles with a high-clearance molded housing; portal builds use Currie F9 and F10 axles with a 1.67:1 ratio and an available 1.4:1 overdrive set. Choose straight axles for simplicity and portal axles for wheel-level clearance and overdrive tuning.
• Overdrive as a stock part vs an upgrade: The Currie Portal Overdrive Gear Set (20/28) is the stock replacement for the VS4-10 Ultra and VS4-10 Phoenix (VPS09007) kits, but on other portal axles it is a change you make yourself. Verify what your kit ships with before buying a gear set you may already have.
• Shared drivetrain parts vs platform-specific body parts: The VFD Light Weight Aluminum Motorplate fits VPS09003, VPS09004, and the VPS10152 VFD Transmission Kit, while the Incision Series 3 Light Kit is designed for the VS4-10 Phoenix and Origin Classic bodies. Drivetrain parts travel between builds; body and lighting parts usually do not.

Catalog facts that affect your choice

• VS4-10 Builders Kit - Straight Axle: Features the Vanquish Products VFD transmission and F10 straight axles, connected by ISD10 driveshafts with machined CV-style joints; the molded F10 straight axles use a high-clearance design that minimizes the pumpkin and maximizes strength around the C-hub and knuckle. This is the simplest VS4-10 entry point and the one to pick if you want a single-box drivetrain without portal gear maintenance.
• Currie Portal Overdrive Gear Set (20/28): A 1.4:1 gear ratio versus the 1.67:1 ratio included in the portal axles; suggested for the front axle only, or front and rear; stock replacement for the VS4-10 Ultra and VS4-10 Phoenix (VPS09007) kits. If you run a portal VS4-10, this is the tuning part that changes climbing and turning behavior, and it is a direct replacement rather than a custom fit.
• VFD Light Weight Aluminum Motorplate: ポータルビルドは逆のアプローチです。Currie F9 および F10 ポータルアクスルは、納品時点で 1.67:1 のギア比を備え、Currie Portal Overdrive Gear Set (20/28) を使用すると 1.4:1 に下がります。ポータルボックスはホイール位置での地上高を増やしますが、部品と調整ポイントも増えます。どちらのレイアウトも普遍的に優れているわけではなく、トレイル上で異なる場所で問題が発生するだけです。
• Straight axles: fewer moving parts, simpler to service, less clearance under the diff. Portal axles: more clearance at the wheel, more gear interfaces to maintain.
