Marlin Crawler R-series Transmission Billet Shift Fork, 1st/2nd GearOld vs New Shift Fork Design

We are proud to release v2.0 of our high strength 7075-T6 billet aluminum R-series transmission 1st-2nd shift fork!

Our new updated version features Marlin Crawler red anodizing and a new full contact wrap-around design. We are now utilizing a 100% full face fork-to-shift-hub contact for improved wear now vastly superior to the stock Toyota part!

For R-series 5-speed transmissions, this high strength shift fork is much stronger than the stock cast aluminum fork that wears out and fails.

We looked at a huge bucket of broken and worn out stock forks and designed our 7075-T6 fork to combat all of the weak spots. The result is the strongest 1st-2nd shift fork in the world for your 2WD or 4WD Toyota R150F R151F, R154, and Jeep AX15 5-speed transmission.

Sold individually, one fork is required per transmission.

R-Series Shift Fork Comparison: Marlin Crawler vs Stock

Here we are comparing our 7075-T6 fork on the left with the stock fork on the right. Our high quality billet material is more durable and will greatly reduce this common wear-out problem.

This is the fate of many stock forks. We use stronger material and more of it for durability and performance that lasts! Feel free to slam those gears!
