Q: Have a F150 High Trail with Yeah Racing front and rear Alloy, Stainless Steel axle with under drive gears, front axle has FI spool, lowered battery mount. Will the steel portal package be to heavy? Do you have steel portals for the rear?

Asked by: Francis Garwacki - 3/5/2026

A: We find the steel portal package is a nice medium weight. Not as heavy as brass but certainly more than the stock plastic or aluminum.

We only make the full setup for the front as we prefer a front weight bias for climbing. If you want an increase in strength for the rear, we suggest looking at the aluminum parts we sell from Devil RC.

Q: Installed the kit when I tighten the upper and lower C hub screws steering gets tight.

Asked by: Francis - 4/23/2026

A: These are intended to remove slop compared to stock.

It may be very tight at first, but should break in allowing for a tight, but workable fit.
Some grease could be applied if you feel it is overly tight.
Some gentle polishing could speed up that break in period as well.
