Pioneer Tarp Arm Assembly Parts
Replacement arm assembly parts for Pioneer Tarp systems — arm springs, hinges, mounting hardware, and complete arm assemblies. The spring-loaded arms that pull the tarp across the load.
What this page covers
The arm assembly is the heart of a Pioneer mesh-arm tarp system. Spring-loaded arms tension the tarp as it deploys, hold it taut during transport, and retract it for loading. Arm springs lose tension over time; hinges wear at pivot points; mounting hardware fatigues from cycling.
PRT stocks the arm assembly wear parts plus complete arm assemblies for major replacement.
How to choose
Match by Pioneer Tarp model, arm length, spring rate, and mounting style.
Replace arm springs in matching pairs — uneven spring tension causes tarp misalignment and accelerated wear.
Arm assembly options
- Arm springsReplacement coil and extension springs.
- Arm hingesPivot hinges at the arm attachment point.
- Arm mounting hardwareBrackets, bolts, and pins.
- Complete arm assembliesFull arm with spring, hinge, and mounting.
- Custom-length armsFor non-standard truck bed dimensions.
- Arm end capsTarp attachment hardware at arm ends.
Frequently asked questions
How long do Pioneer Tarp arm springs last?
3-7 years depending on cycle frequency. Weakened springs cause tarp sag and incomplete coverage — replace at the first sign of reduced tension.
Should I replace both arm springs at the same time?
Yes. Mismatched spring tension between left and right arms causes tarp misalignment and accelerated wear on the new spring.
Are PRT arm assembly parts OEM-equivalent for Pioneer Tarp?
Yes. PRT parts match OEM Pioneer dimensions, spring rates, and mounting patterns.
Can I get custom-length arms for an unusual truck bed?
Yes. PRT can fabricate custom-length arms to spec — typical lead time 1-2 weeks.
