It depends on your motor and the track. In the 1/10 4WD buggy class, racers gear by final drive ratio: 6T and below near 10.66, 7.5–8.5T near 10.00, 13.5T near 7.95. On the 22X-4's stock 81T spur that is about 19T for 6T and below, 20T for 7.5–8.5T, 25T for 13.5T. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the 22X-4 selected.
What is the internal ratio (transmission ratio) of the TLR 22X-4?
The 22X-4 has an internal ratio of 2.5:1. Final drive ratio = spur ÷ pinion × 2.5. With the stock 81T spur, a 16T pinion gives an FDR of 12.66 and a 28T gives 7.23.
How many teeth is the stock spur gear on the TLR 22X-4?
81 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.

What shock oil does the TLR 22X-4 come with?
Out of the box the 22X-4 runs 42.5 wt front, 40 wt rear (Team Losi oil), on Thin 2 x 1.6mm (#333014) front, Thin 2 x 1.7mm (#333016) rear pistons. That is the kit setup; you will need to adjust it for your track conditions. The RC Setup App can help dial it in.
What springs does the TLR 22X-4 come with?
The kit springs are LF Yellow (#233053) front, LF Pink (#233058) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
What diff fluid does the TLR 22X-4 come with?
The kit diff fluid is 7,000 cst front, 5,000 cst rear. Thicker front adds steering on power; thicker center sends more drive rearward; thicker rear stabilizes the car under throttle.
