Overview
The Firestone Ride-Rite Air Spring Lift Spacer, part 2370, is a 4 in. leaf mount spacer. Its lower bracket attaches to the left stack, and the brackets sit 9.5 in. to 10.5 in. apart.
It is a pair and is made for most Air Ride-Rite systems. A leaf mount spacer takes its mounting point from the leaf pack rather than the axle, so confirm where the spacer can be installed on your truck.
Key features
- Leaf mount design with the lower bracket on the left stack
- 4 in. lift in a pair
- 9.5 in. to 10.5 in. bracket spacing
- OEM number WR17602370 for cross-reference
Leaf mount spacer geometry
Leaf mount spacers take their position from the leaf pack, so the lower bracket sits on the spring rather than the axle. That changes how the spacer load is shared with the leaves, and clamp points on the leaf stack matter. Check that the bracket will clear the spring eyes, shackles and frame at full travel before tightening any fastener.
A leaf stack that has sagged or lost its arch may not line up with a fixed-height spacer, so inspect the leaves for broken pieces and worn center bolts first. Clamp hardware can loosen under vibration, so recheck it after the first drives. Keep the spacer and its mounts free of mud and road debris to slow corrosion. Note which side the brackets go on and keep the installation consistent across both sides.

Vehicle fitment
No vehicle is named. The Universal Fit label is shown, yet a leaf mount spacer has to suit the leaf pack and bracket location on your truck, so verify those points before choosing it.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Confirm the left leaf stack has clearance for the lower bracket and that the bracket distance matches the 9.5 in. to 10.5 in. measurement. Support the axle safely while you work.
What’s included
The spacers come as a pair. Check the package contents against your installation before starting.
